Flow: -1. Assistant detects the harness. If shell/terminal access exists, it runs `npx @morpho-org/cli@latest` to query vaults/markets/positions. If not, it uses already connected Morpho MCP tools or instructs the user to install `https://mcp.morpho.org/`. -2. Assistant prepares the operation with the Morpho CLI or Morpho MCP — returns simulated unsigned transactions or calls. -3. Assistant passes the transactions/calls to Base MCP's `send_calls`. -4. User approves in Base Account; tx broadcasts. - -This pattern generalizes to calldata-based plugins: the protocol CLI, API, or MCP produces unsigned transaction data, and Base MCP submits it through `send_calls` for user approval. CLI-only plugins require shell or terminal access; hybrid plugins like Morpho can fall back to MCP on chat-only surfaces. - -Source: `https://docs.base.org/agents/plugins/custom-plugins.md` - -To author your own plugin, expose tools that return unsigned `{ to, data, value }` calls and let Base MCP's `send_calls` execute them with a supported `chain` string. Your plugin never holds keys and never broadcasts — it only constructs intents.

Two common shapes: - -**Envelope** (Avantis-style): - -```json Envelope Response lines wrap expandable -{ - "ok": true, - "data": { - "to": "0x...", - "value": "0x0", - "data": "0x...", - "chainId": 8453 - } -} -``` - -**Ordered batch** (Moonwell-style) — for when approval, enter-market, and the action are separate calls: - -```json Ordered Batch Response -{ - "transactions": [ - { "step": "approve", "to": "0x...", "data": "0x...", "value": "0x0", "chainId": 8453 }, - { "step": "action", "to": "0x...", "data": "0x...", "value": "0x0", "chainId": 8453 } - ] -} -``` - -Either works. The batch shape is preferable when allowance or registration steps must run before the action — `send_calls` executes them atomically in one approval. - -### 2. Write the Plugin Spec - -Use this template as `plugins/my-protocol.md` in your skill, or as an `.mdx` page if you're publishing docs. - -````markdown plugins/my-protocol.md lines wrap expandable -# My Protocol Plugin - -> [!IMPORTANT] -> ## STOP — COMPLETE ONBOARDING BEFORE USING THIS PLUGIN -> -> Before calling any My Protocol endpoint, you MUST complete the Base MCP onboarding flow: -> 1.

Wire It Into `send_calls` - -The contract between your prepare endpoint and Base MCP is exactly this object: - -```json send_calls Payload -{ - "chain": "base", - "calls": [ - { "to": "0x...", "value": "0x0", "data": "0x..." } - ] -} -``` - -Use Base MCP's chain names (`base`, `base-sepolia`, `ethereum`, `optimism`, `polygon`, `arbitrum`, `bsc`, or `avalanche`) when calling `send_calls`. If a prepare endpoint returns a numeric or hex `chainId`, map it to the corresponding chain name before calling Base MCP. `value` defaults to `0x0` if omitted. The assistant calls `send_calls` once with the full batch — the user approves once, and all calls execute atomically. - -## Patterns to Copy - -| Pattern | When to use | Example | -|---------|-------------|---------| -| Single-call envelope | One action, one tx | [Avantis](https://github.com/base/skills/blob/master/skills/base-mcp/plugins/avantis.md) | -| Ordered batch | Approval + action must be atomic | [Moonwell](https://github.com/base/skills/blob/master/skills/base-mcp/plugins/moonwell.md) | -| CLI-only prepared batch | Protocol CLI produces calldata; no MCP fallback needed | [Aerodrome](https://github.com/base/skills/blob/master/skills/base-mcp/plugins/aerodrome.md) | -| CLI or MCP prepared batch | Prefer a protocol CLI when shell access exists; fall back to an MCP server on chat-only surfaces | [Morpho](https://github.com/base/skills/blob/master/skills/base-mcp/plugins/morpho.md) | -| Multi-endpoint flow | Quote, approve, swap as separate calls | [Uniswap](https://github.com/base/skills/blob/master/skills/base-mcp/plugins/uniswap.md) | -| Discovery API + swap | Read-only feed selects the token; `swap` executes the purchase | [Bankr](https://github.com/base/skills/blob/master/skills/base-mcp/plugins/bankr.md) | -| MCP server + SIWE session auth | Protocol has its own MCP server; Base MCP wallet signs the login challenge | [Virtuals](https://github.com/base/skills/blob/master/skills/base-mcp/plugins/virtuals.md) | -## Related - - - - Full guide to `send_calls` and batching. - - - Reference implementations for ordered-batch, CLI/MCP-prepared, and multi-endpoint patterns. - - diff --git a/docs/agents/plugins/index.mdx b/docs/agents/plugins/index.mdx deleted file mode 100644 index f1a0bb2aa..000000000 --- a/docs/agents/plugins/index.mdx +++ /dev/null @@ -1,120 +0,0 @@ ---- -title: "Overview" -description: "How the Base MCP Skill works and how plugins extend it" -keywords: ["Base MCP skill", "Anthropic Skills", "SKILL.md", "Base MCP plugins", "send_calls plugin pattern"] ---- - - -This page describes how the Base MCP Skill and Plugins work under the hood.

Without context, models might get confused, calling write tools without warning the user, skipping approval, inventing parameters, or failing to detect that the server isn't connected at all. The skill closes that gap. Specifically, `SKILL.md` adds: - -- **Detection and onboarding** — the assistant can call `get_wallets` when it needs wallet context, supported chains, or an address for a write flow. -- **Approval mode** — write tools (`send`, `swap`, `sign`, `send_calls`) return `{ approvalUrl, requestId }`. The skill tells the model to present the link, wait, then poll `get_request_status` — never to claim success before confirmation. -- **Tone rules** — load-bearing language conventions (e.g. "onchain", never "web3") and a beginner/sophisticated detection heuristic so responses match the user. -- **Plugin patterns** — documented prepare → `send_calls`, `swap`, and `sign` patterns that let external protocols extend the skill without modifying the MCP server. - -## How SKILL.md Is Loaded - -Skills use progressive disclosure.

Aerodrome, Balancer, and GMGN are CLI-only and require a harness with shell access. Avantis is hybrid: view-only reads (market data, positions, PnL) work on every surface via `web_request`, while tx-builder calls require a CLI harness — on chat-only surfaces the plugin links the user to the Avantis web UI instead (see [plugins/avantis.md](./plugins/avantis.md)). Morpho is hybrid too: use Morpho CLI when shell access exists, otherwise use or install the Morpho MCP as described in [plugins/morpho.md](./plugins/morpho.md). Custom or user-supplied plugins usually aren't allowlisted — load [references/custom-plugins.md](./references/custom-plugins.md) for the decision tree on which HTTP path to use (harness HTTP tool vs. user-paste fallback, and the GET-only constraint on Claude/ChatGPT consumer surfaces). - -## Installation - -```bash -npx skills add base/skills --skill base-mcp -``` diff --git a/docs/agents/skills/plugins/aerodrome.md b/docs/agents/skills/plugins/aerodrome.md deleted file mode 100644 index 1f30390d6..000000000 --- a/docs/agents/skills/plugins/aerodrome.md +++ /dev/null @@ -1,366 +0,0 @@ ---- -title: "Aerodrome Plugin" -description: "Swap, provide liquidity, stake, and claim rewards on Aerodrome." -tags: [dex, swap, liquidity, staking] -name: aerodrome -version: 0.2.0 -integration: cli-only -chains: [base] -requires: - shell: required - allowlist: [] - externalMcp: null - cliPackage: "uvx --from git+https://github.com/velodrome-finance/sugar-sdk.git@v0.4.0 sugar" -auth: none -risk: [slippage] ---- - -# Aerodrome Plugin - -> [!IMPORTANT] -> Complete the short Base MCP onboarding flow defined in `SKILL.md` before calling any Aerodrome flow. - -## Overview - -Aerodrome is the main Velodrome-style DEX on Base.

Fetch the wallet address only when needed with `get_wallets`. -3. Set `SUGAR_RPC_URI_8453` to a reliable Base RPC. -4. Run the Sugar CLI command. -5. Parse stdout as JSON. Diagnostics and warnings are on stderr. -6. Normalize `[{from,to,data,value}]` into Base MCP `calls` (see [Submission](#submission)). -7. Submit with `send_calls({ "chain": "base", "calls": [...] })`. -8. Show the approval URL when appropriate. -9. Poll `get_request_status` only after the user acts in Base Account. - -If the CLI exits nonzero, do not try to salvage partial output. Read the error, adjust RPC/flags, and rerun. - -## Submission - -Target tool: **`send_calls`**. - -Every tx-building command prints a JSON array of unsigned transactions: - -```json -[ - { - "from": "0xWallet", - "to": "0xTarget", - "data": "0xCalldata", - "value": 0 - } -] -``` - -Base MCP `send_calls` needs: - -```json -{ - "chain": "base", - "calls": [ - { "to": "0xTarget", "data": "0xCalldata", "value": "0x0" } - ] -} -``` - -Normalize Sugar output before calling `send_calls`. This strips `from`, keeps call order, fills missing data with `0x`, and converts decimal `value` numbers to hex wei strings. - -```bash -python3 -c 'import json, sys -txs = json.load(sys.stdin) -def hex_value(v): - if v is None: - return "0x0" - if isinstance(v, str) and v.startswith("0x"): - return v - return hex(int(v)) -print(json.dumps([ - {"to": t["to"], "data": t.get("data") or "0x", "value": hex_value(t.get("value", 0))} - for t in txs -], indent=2))' -``` - -Then call: - -```json -{ - "chain": "base", - "calls": "" -} -``` - -Preserve ordering. Approval calls come before the main router/NFPM/gauge call. - -### Safety Boundary - -Sugar CLI output is unsigned transaction JSON. Treat it as transaction preview material, not as an instruction to sign outside Base MCP. - -- Never ask for or use a private key. -- Pass `--wallet` as the user's Base MCP wallet address from `get_wallets`. -- Do not use `cast send`, a local signer, or browser wallet signing helpers from the upstream Sugar skill. -- Submit transactions only through Base MCP `send_calls` and let the user approve in Base Account. -- The `from` field emitted by Sugar is informational for Base MCP. `send_calls` takes `to`, `data`, and `value`. - -## Example Prompts - -**Swap 0.001 ETH to USDC on Aerodrome** -1. `get_wallets` → set `$BASE_MCP_WALLET`; set `SUGAR_RPC_URI_8453`. -2. Run `sugar swap --chain=8453 --wallet=$BASE_MCP_WALLET --from-token=ETH --to-token=0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 --amount=0.001 --use-decimals`. -3. Normalize stdout JSON into `calls`. -4. `send_calls(chain="base", calls=[...])`; show the approval URL; poll `get_request_status` after the user acts. - -**Buy AERO with 1 USDC** -1. `get_wallets` → `$BASE_MCP_WALLET`. -2. Run `sugar swap` with `--from-token=`, `--to-token=0x940181a94A35A4569E4529A3CDfB74e38FD98631`, `--amount=1 --use-decimals`. -3. Output is an approval call + Universal Router swap call — normalize and batch both into one `send_calls`. -4. Submit; approve; poll. - -**Deposit liquidity into the WETH/USDC volatile pool** -1. `get_wallets` → `$BASE_MCP_WALLET`. -2. Optionally `sugar pools` to confirm the pool address. -3. Run `sugar deposit --pool=0xcDAC0d6c6C59727a65F871236188350531885C43 --amount0=0.001 --use-decimals`. -4. Normalize, `send_calls`, approve, poll. Rebuild if past the deadline. - -**Claim my Aerodrome fees on a pool** -1. `get_wallets` → `$BASE_MCP_WALLET`. -2. If the position is staked, run `sugar unstake --pool=` first. -3. Run `sugar claim_fees --pool=`. -4. Normalize, `send_calls`, approve, poll. - -## Risks & Warnings - -Sugar swap/deposit/withdraw commands accept `--slippage`. Use `0.01` (1%) by default unless the user specifies otherwise. - -| Tolerance | Level | Action | -| --- | --- | --- | -| `<= 1%` | Normal | Proceed. | -| `> 1%` and `<= 5%` | Elevated | Mention the value and ask the user to confirm. | -| `> 5%` and `<= 20%` | High | Warn that execution can be materially worse than quote. Require explicit confirmation. | -| `> 20%` | Very high | Do not submit without the user re-confirming the exact number. | - -## Notes - -### Tested CLI Behavior and Gotchas - -Tested on 2026-05-25 from the `worktree-sugar-cli-skill` branch of `velodrome-finance/sugar-sdk`. The runner installed Sugar SDK `v0.4.0`. - -What worked: - -- `scripts/sugar-doctor.sh` detected `uvx` and reported Base RPC configuration. -- `scripts/sugar-run.sh --help` installed and ran the CLI. -- `pools --chain=8453 --limit=3` returned JSON pool data. -- `pools` with WETH/USDC address filters returned the volatile and stable basic pools listed above. -- Native ETH to USDC swap built a Universal Router call. -- USDC to AERO swap built an approval call plus a Universal Router call. - -Observed gotchas: - -- In a sandbox, the first `uvx` run failed with `failed to create directory ~/.local/share/uv/tools`. Setting `UV_TOOL_DIR` and `UV_CACHE_DIR` to writable directories fixed it. -- The built-in Base public RPC produced `Web3RPCError` path chunk warnings, `token not found: USDC`, and a routing failure (`source node ... WETH not in graph`) during swap testing. Set `SUGAR_RPC_URI_8453` before tx-building. -- `https://base-rpc.publicnode.com` worked for simple pools and swaps in testing, but still emitted `429 Too Many Requests` warnings and timed out on read-heavy `positions` and `deposit` paths. Prefer a paid or otherwise reliable RPC for production usage. -- CLI diagnostics go to stderr and JSON goes to stdout. Capture stdout only when passing output into the normalizer. -- `--help` may display Python-style underscore flags such as `--from_token`; Fire accepted hyphenated flags such as `--from-token` in testing. -- Symbols can be ambiguous. Use token addresses for production flows, especially for USDC and AERO. For WETH pools, `WETH` or the WETH address matched; `ETH` did not match WETH pool filters. -- Sugar emits `value` as a JSON number in tested swap output. Base MCP `send_calls` expects hex strings such as `"0x0"` or `"0xe8d4a51000"`. - -### Base Token Addresses - -| Token | Address | -| --- | --- | -| Native ETH pseudo-token | `ETH` | -| WETH | `0x4200000000000000000000000000000000000006` | -| USDC | `0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913` | -| AERO | `0x940181a94A35A4569E4529A3CDfB74e38FD98631` | - -### Key Aerodrome Contracts - -| Contract | Address | -| --- | --- | -| Sugar | `0x69dD9db6d8f8E7d83887A704f447b1a584b599A1` | -| Router | `0xcF77a3Ba9A5CA399B7c97c74d54e5b1Beb874E43` | -| Universal Router | `0x01D40099fCD87C018969B0e8D4aB1633Fb34763C` | -| Slipstream | `0x0AD09A66af0154a84e86F761313d02d0abB6edd5` | -| Nonfungible Position Manager | `0x827922686190790b37229fd06084350E74485b72` | diff --git a/docs/agents/skills/plugins/avantis.md b/docs/agents/skills/plugins/avantis.md deleted file mode 100644 index b213a0607..000000000 --- a/docs/agents/skills/plugins/avantis.md +++ /dev/null @@ -1,978 +0,0 @@ ---- -title: "Avantis Plugin" -description: "Open and manage leveraged perpetual-futures positions on Avantis." -tags: [perps, leverage, trading, derivatives] -name: avantis -version: 0.2.0 -integration: hybrid -chains: [base] -requires: - shell: optional - allowlist: [data.avantisfi.com, core.avantisfi.com, api.avantisfi.com] - externalMcp: null - cliPackage: null -auth: none -risk: [liquidation, slippage, irreversible] ---- - -# Avantis Plugin - -> [!IMPORTANT] -> Complete the short Base MCP onboarding flow defined in `SKILL.md` before calling any Avantis endpoint. The user's wallet address — used as `trader` in every tx-builder call — is fetched lazily when needed. - -## Overview - -Avantis is a perpetual futures DEX on Base mainnet (`chainId` 8453). The plugin returns **unsigned** call data; signing and broadcasting are the wallet's job (Base MCP `send_calls`). Collateral is USDC only; ETH is used only for gas and the Avantis execution-fee `value`. View-only reads work on every surface; transaction-building needs a CLI/HTTP harness, with an Avantis web UI fallback on chat-only surfaces. Aligned with the canonical `Avantis-Labs/avantis-trading-skill` spec. - -## Surface Routing - -| Capability | Hosts | Where it runs | -| --- | --- | --- | -| **View-only reads** — pair config, leverage envelopes, fees, open positions, limit orders, trade history, PnL, market-order settlement | `data.avantisfi.com`, `core.avantisfi.com`, `api.avantisfi.com` | Every surface. Use the harness HTTP tool when available; otherwise Base MCP `web_request` — these hosts are on the allowlist. | -| **Transaction-builder** — open/close trades, cancel orders, deposit/withdraw margin, set TP/SL, approve USDC, set/remove delegate | `tx-builder.avantisfi.com` | CLI harnesses (Claude Code, Codex, Cursor terminal). On chat-only surfaces (ChatGPT, Claude.ai), do not retry through `web_request`; link the user to the Avantis web UI — see [Chat-only fallback](#chat-only-fallback-avantis-ui). | - -Routing order for any Avantis HTTP call: - -1. **Harness HTTP tool** (`curl`, `fetch`, shell) — works for every host, any method, no allowlist. -2. **Base MCP `web_request`** — chat-only surfaces, view-only hosts only. -3. **Avantis web UI** — chat-only surfaces, tx-builder operations. See [Chat-only fallback](#chat-only-fallback-avantis-ui). - -Do not sign, approve, or submit transactions unless the user explicitly asks. Generating call data and `send_calls` approval links is safe; the user approves any real transaction. - -No API key or Authorization header is required for the documented public endpoints. The general HTTP routing rules also live in [../references/custom-plugins.md](../references/custom-plugins.md). - -> [!IMPORTANT] -> **CORS caveat for `web_request`.** Most Avantis hosts return `Access-Control-Allow-Origin: *`, but two paths are **not** in the open-CORS prefix list: -> - `https://api.avantisfi.com/v2/history/referral/*` -> - `https://api.avantisfi.com/v2/market-order-initiated/*` -> -> Base MCP `web_request` is a server-side fetch and is not affected by browser CORS, so these still work from `web_request`. Only flag this if you ever proxy these requests from a browser context. - -### Chat-Only Fallback: Avantis UI - -When the user wants a tx-builder action (open, close, cancel, margin update, TP/SL change, USDC approval, delegate set/remove) and there is no shell, terminal, or direct HTTP tool in the current surface (typical for ChatGPT, Claude.ai): - -1. Use `web_request` against `data.avantisfi.com`, `core.avantisfi.com`, or `api.avantisfi.com` to answer the read side of the question (pair info, the user's open positions, recent PnL). -2. Tell the user plainly that signing and submitting Avantis trades from this surface requires the Avantis web UI (or a CLI harness like Claude Code, Codex, or Cursor terminal). -3. Build a deep link to the relevant market and surface it as a clickable link. URL pattern: - - ``` - https://www.avantisfi.com/trade?asset=-USD - ``` - - `` is the pair's `from` from `pairInfos[""]` (e.g. `BTC`, `ETH`, `SNDK`). Examples: - - - `https://www.avantisfi.com/trade?asset=ETH-USD` - - `https://www.avantisfi.com/trade?asset=BTC-USD` - - `https://www.avantisfi.com/trade?asset=SNDK-USD` - -4. If the user already supplied concrete trade parameters (side, leverage, collateral, TP, SL), summarize them in your message so they can reproduce the intent inside the UI. Do not claim the position was opened or modified — the UI flow is user-driven. - -Only use this fallback for tx-builder operations.

Warn the user before submitting elevated values; the protocol max slippage is 80% (`_MAX_SLIPPAGE`). Don't silently raise it. -- **Leverage.** Respect the per-pair envelope (`leverages.*`); the server sanity cap (`<= 1000`) is far looser than the per-pair max in `meta.validation.maxLeverage`. -- **Irreversible.** Market opens/closes settle onchain and cannot be undone.

Quotes are not offered without the ability to execute them. - -## Overview - -Balancer is an automated market maker (AMM) for token swaps and liquidity provision on Base, Ethereum, Arbitrum, Optimism, and Avalanche (v2 and v3 pools, including yield-bearing "boosted" pools). This plugin runs entirely in a shell: it **reads** pool data and Smart Order Router (SOR) quotes from the Balancer API (`https://api-v3.balancer.fi`) with `curl`, **encodes unsigned calldata** for the chosen action with the Balancer SDK (`@balancer/sdk`), and submits it through Base MCP `send_calls`. The API returns swap *paths* and pool state, **not** calldata — the SDK's `buildCall()` turns a path/pool plus a slippage tolerance into the `{ to, callData, value }` a transaction needs, and its `query()` simulation needs a Base RPC. Because every step requires running code (`curl`, then Node), the plugin is **CLI-only**: on a surface without a shell it cannot run — see [`## Surface Routing`](#surface-routing). - -## Surface Routing - -| Capability | Surface with shell (Claude Code, Codex, Cursor) | Chat-only surface (Claude.ai, ChatGPT) | -|---|---|---| -| Read pools / quotes (`curl` the Balancer API) | ✅ harness HTTP tool / `curl` | ❌ unsupported | -| Build + submit a swap or LP change (Node SDK → `send_calls`) | ✅ run the SDK script, then `send_calls` | ❌ unsupported | - -This plugin is **CLI-only** — it needs shell/terminal access for every operation, including reads (calldata can only be built by running the SDK, and quotes alone aren't useful without it). On a chat-only surface, do not improvise: no user-paste URL, no substitute MCP. Tell the user the Balancer plugin requires a shell (e.g. Claude Code) and stop; if they only want to act manually, point them to `https://balancer.fi`. - -## Commands - -Everything runs in the agent's shell. Reads are HTTP POSTs to the Balancer API via `curl` (or the harness HTTP tool). Writes build calldata with a short Node script using `@balancer/sdk` (there is **no Balancer CLI** — the SDK is a library you import). One-time setup in a working dir: - -```bash -npm init -y >/dev/null 2>&1 -npm i @balancer/sdk viem -export RPC_URL="" # buildCall's query() simulation needs an RPC -``` - -`chain` arguments take the API's uppercase `GqlChain` enum (`BASE`, `MAINNET`, `ARBITRUM`, `OPTIMISM`, `AVALANCHE`), not the Base MCP chain string — see [`## Notes`](#notes). The API is keyless and self-documenting via GraphQL introspection; if a query errors on a field, confirm names against the live schema. - -### Read Pools & Quotes - -Single endpoint: `POST https://api-v3.balancer.fi/` with a JSON `{ "query", "variables" }` body, run with `curl`. - -**Quote / route a swap** — `sorGetSwapPaths` (returns paths + expected amounts + price impact; no calldata): - -```graphql -query SwapPaths($chain: GqlChain!, $tokenIn: String!, $tokenOut: String!, $swapType: GqlSorSwapType!, $swapAmount: AmountHumanReadable!) { - sorGetSwapPaths(chain: $chain, tokenIn: $tokenIn, tokenOut: $tokenOut, swapType: $swapType, swapAmount: $swapAmount) { - returnAmount - priceImpact { priceImpact error } - paths { protocolVersion pools isBuffer inputAmountRaw outputAmountRaw tokens { address decimals } } - } -} -``` - -`swapType`: `EXACT_IN` (amount is the input) or `EXACT_OUT` (amount is the desired output). `swapAmount` is human-readable (e.g. `"100"`). The returned `paths[].protocolVersion` drives the submission batch (see [`## Submission`](#submission)). - -`priceImpact.priceImpact` is **nullable**: for some valid multi-hop routes the API can't compute it and returns `{ priceImpact: null, error: "Price impact could not be calculated for this path. The swap path is still valid and can be executed." }` (USDC→WETH does this right now). Treat a null with that message as *unknown*, **not** as a failure or a high-impact warning — say "price impact unavailable", fall back to comparing the SOR `returnAmount` against the input (and the pool's TVL), and don't block the swap on it. Only a non-null, genuinely high `priceImpact` is a warning sign (see [`## Risks & Warnings`](#risks--warnings)). - -**Discover pools** — `poolGetPools` (filter, sort by TVL/APR): - -```graphql -query Pools($first: Int, $orderBy: GqlPoolOrderBy, $orderDirection: GqlPoolOrderDirection, $where: GqlPoolFilter) { - poolGetPools(first: $first, orderBy: $orderBy, orderDirection: $orderDirection, where: $where) { - id address chain type name symbol protocolVersion - dynamicData { totalLiquidity volume24h aprItems { apr type } } - poolTokens { address symbol weight } - } -} -``` - -Example variables: `{ "first": 10, "orderBy": "totalLiquidity", "orderDirection": "desc", "where": { "chainIn": ["BASE"], "minTvl": 100000 } }`. Single pool: `poolGetPool(id, chain)`. Tokens/prices: `tokenGetTokens(chains)`, `tokenGetCurrentPrices(chains)`. A pool's `id` is the argument to the SDK's `fetchPoolState`. - -### Build a Swap (`build-swap.mjs`) - -Fetch SOR paths, simulate, then encode the action call **together with its version-correct approval(s)** and emit a ready-to-submit payload — `{ chain, calls }` (plus `protocolVersion`/`minAmountOut` for display) that maps straight onto `send_calls`. Building the whole batch in the script (not just the action call) is deliberate: each approval's target is derived from the **same `call.to` the SDK returns**, so a v3 Permit2 approval can never be hand-paired with a v2 Vault target. That mismatch passes per-call encoding (each approval is individually valid) and only reverts at the action call — usually as an uninformative `unable to estimate gas`. ERC20 input only; for native-ETH input set `wethIsEth: true` and drop the approval call(s) (see [`## Submission`](#submission)). - -```js -import { BalancerApi, Swap, SwapKind, Slippage, ChainId, Token, TokenAmount } from "@balancer/sdk"; -import { encodeFunctionData } from "viem"; - -const chainId = ChainId.BASE; -const RPC_URL = process.env.RPC_URL; -// args: sender (wallet from get_wallets), tokenIn, tokenInDecimals, tokenOut, humanAmount, slippagePct -const [sender, tokenIn, decIn, tokenOut, amount, slippagePct = "0.5"] = process.argv.slice(2); - -const PERMIT2 = "0x000000000022D473030F116dDEE9F6B43aC78BA3"; // canonical Permit2, same on every chain -const CHAIN_STRINGS = { 8453: "base", 1: "ethereum", 42161: "arbitrum", 10: "optimism", 43114: "avalanche" }; - -const api = new BalancerApi("https://api-v3.balancer.fi/", chainId); -const inAmount = TokenAmount.fromHumanAmount(new Token(chainId, tokenIn, Number(decIn)), amount); -const paths = await api.sorSwapPaths.fetchSorSwapPaths({ - chainId, tokenIn, tokenOut, swapKind: SwapKind.GivenIn, swapAmount: inAmount, -}); - -// The SOR routes per pair through Balancer v2 or v3. v3 makes msg.sender the sender/recipient; -// v2 settles through the V2 Vault and REQUIRES sender/recipient — without them buildCall throws -// "Input Validation: Swap input missing parameter sender/recipient for Balancer v2". -const usesV2 = paths.some((p) => p.protocolVersion === 2); - -const swap = new Swap({ chainId, paths, swapKind: SwapKind.GivenIn }); -const queryOutput = await swap.query(RPC_URL); // onchain simulation → expected out -const call = swap.buildCall({ - queryOutput, - slippage: Slippage.fromPercentage(slippagePct), // sets minAmountOut - deadline: 9999999999n, - ...(usesV2 ? { sender, recipient: sender } : {}), // v2 only; v3 rejects sender/recipient - wethIsEth: false, // true → use native ETH as tokenIn/out -}); - -// Assemble the FULL send_calls array here, deriving every approval target from the SAME call.to -// the SDK returned — so a v3 Permit2 approval can't be paired with a v2 Vault target. -const amountIn = inAmount.amount; // raw base units (bigint) -const ERC20_APPROVE = [{ name: "approve", type: "function", stateMutability: "nonpayable", - inputs: [{ name: "spender", type: "address" }, { name: "amount", type: "uint256" }], outputs: [{ type: "bool" }] }]; -const PERMIT2_APPROVE = [{ name: "approve", type: "function", stateMutability: "nonpayable", - inputs: [{ name: "token", type: "address" }, { name: "spender", type: "address" }, - { name: "amount", type: "uint160" }, { name: "expiration", type: "uint48" }], outputs: [] }]; -const approve = (spender) => encodeFunctionData({ abi: ERC20_APPROVE, functionName: "approve", args: [spender, amountIn] }); -const hex = (v) => "0x" + (v ?? 0n).toString(16); - -const calls = []; -if (usesV2) { - // v2: plain ERC20 allowance to the V2 Vault (call.to), then the Vault call.

Batch the version-correct approval for each ERC20 deposited (v3: Permit2; v2: Vault) then the action call → `send_calls` → approve → confirm. - -## Submission - -Target tool: **`send_calls`** (EIP-5792 batch — see [../references/batch-calls.md](../references/batch-calls.md)). For a swap, `build-swap.mjs` already emits the complete batch in its `calls` array — submit that directly; the breakdown below is what it contains (verify before approving) and the template the add/remove-liquidity scripts follow. The approval that must precede the action call **depends on the path's `protocolVersion`** (the value the script emits; the SOR chooses v2 or v3 per pair). `send_calls` submits *unsigned* calls, so grant any allowance onchain in the batch — never `buildCallWithPermit2` (it bakes in an EIP-712 signature). For an ERC20 input/deposit: - -**v3 (`protocolVersion: 3`)** — settles through a v3 Router (`call.to`) that pulls tokens via **Permit2**. Batch in order: - -1. `tokenIn.approve(PERMIT2, amountIn)` — ERC20 `approve(address,uint256)` to canonical Permit2 `0x000000000022D473030F116dDEE9F6B43aC78BA3`. Skip if allowance already covers `amountIn`. -2. `PERMIT2.approve(tokenIn, router, amountIn, expiration)` — Permit2 AllowanceTransfer `approve(address,address,uint160,uint48)`, `router` = `call.to`. -3. The Router call: `{ to: call.to, value: call.value, data: call.callData }`. - -**v2 (`protocolVersion: 2`)** — settles through the **Balancer V2 Vault** (`call.to` = `0xBA12222222228d8Ba445958a75a0704d566BF2C8`, same on every chain), which pulls tokens via a **plain ERC20 allowance to the Vault — no Permit2**. Batch in order: - -1. `tokenIn.approve(VAULT, amountIn)` — ERC20 `approve(address,uint256)` to the V2 Vault (`call.to`). Skip if already approved. -2. The Vault call: `{ to: call.to, value: call.value, data: call.callData }`. - -For a **native-ETH** input (`wethIsEth: true`), omit the approval call(s) and pass the ETH via `value` (both versions).

If they only want to act manually, point them to `https://balancer.fi/swap`. - -## Risks & Warnings - -- **slippage** — swaps and liquidity changes can fill worse than quoted. The SDK derives `minAmountOut` / `minBptOut` (and `minAmountsOut` on removes) from the slippage you pass to `buildCall` (default 0.5%). Show the user the SOR `returnAmount` and `priceImpact` before submitting, and confirm the slippage. Never silently widen slippage to force a fill — re-quote and let the user decide. -- **low-liquidity** — thin or newly-created pools mean large price impact, failed fills, and impermanent-loss exposure on volatile pairs. Check the pool's `dynamicData.totalLiquidity` (TVL) and the SOR `priceImpact` before swapping or LPing; warn the user when `priceImpact` is high (e.g. > 1%). A **null** `priceImpact` carrying the API's "…still valid and can be executed" note is *unknown*, not high — don't treat it as an error or silently block on it; say it's unavailable and fall back to TVL and the `returnAmount`. Don't auto-route through, or LP into, a pool the user didn't intend, and don't add liquidity to a pool you couldn't read TVL for. - -## Notes - -- **No CLI / shell required** — there is no published Balancer CLI; the shell path is a short Node script using `@balancer/sdk` (hence `cliPackage: null`, `shell: required`). The SDK encodes calldata locally and its `query()` needs a Base RPC, so calldata cannot be produced without running code — there is no chat-only path. -- **API** — `https://api-v3.balancer.fi/` (test: `https://test-api-v3.balancer.fi/`); public GraphQL, keyless, rate-limited. Reached from the shell with `curl` / the harness HTTP tool, so the host needs no allowlisting (`allowlist: []`). Self-documenting via introspection. The schema defines a `GqlSorCallData` type but no query returns it — the API does not hand back calldata. -- **Chain mapping** — API `GqlChain` (uppercase) ↔ Base MCP chain string ↔ SDK `ChainId`: `BASE`/`base`/`8453`, `MAINNET`/`ethereum`/`1`, `ARBITRUM`/`arbitrum`/`42161`, `OPTIMISM`/`optimism`/`10`, `AVALANCHE`/`avalanche`/`43114`. `GqlChain` uses `MAINNET` for Ethereum, not `ethereum`. -- **SDK** — `@balancer/sdk` (the `b-sdk` repo). `Swap` / `AddLiquidity` / `RemoveLiquidity` each expose `.query(rpcUrl)` → `.buildCall(...)` → `{ to, callData, value, minAmountOut | minBptOut | minAmountsOut }`. `query()` needs a Base RPC HTTPS URL. In v3, `msg.sender` is sender and recipient (no `sender`/`recipient` params); **v2 `buildCall` requires `sender` and `recipient`** — pass the wallet for any pair the SOR routes through v2, or it throws `Input Validation: Swap input missing parameter sender/recipient for Balancer v2`. -- **Permit2 (v3 only)** — canonical address `0x000000000022D473030F116dDEE9F6B43aC78BA3` on every chain. v3 Routers pull funds via Permit2; with unsigned `send_calls` batches, grant the allowance onchain (the two approve calls in [`## Submission`](#submission)) instead of `buildCallWithPermit2`'s signature. v2 doesn't use Permit2 — it approves the V2 Vault directly (see below). -- **Router addresses** — always use the `to` the SDK returns; don't hardcode. The SDK picks the right Router per chain/version (e.g. boosted/ERC4626 "nested" pools on Base route through the Composite Liquidity Router `0xf23b4DB826DbA14c0e857029dfF076b1c0264843`). Canonical list: the [Base deployment-addresses page](https://docs.balancer.fi/developer-reference/contracts/deployment-addresses/base.html). -- **v2 vs v3 settlement** — the SOR routes each pair through v2 or v3 by liquidity (common Base pairs like USDC↔WETH, WETH↔cbETH, USDC↔DAI currently route **v2**), and `buildCall` returns the version-correct target: a **v3 Router**, or the **Balancer V2 Vault** `0xBA12222222228d8Ba445958a75a0704d566BF2C8` (same on every chain). Consequences: v2 needs `sender`/`recipient` on `buildCall` and a plain ERC20 approval to the Vault; v3 omits them and approves via Permit2. The script emits `protocolVersion` so the agent picks the right batch. `isBuffer: true` steps are ERC4626 wrap/unwrap hops through v3 boosted-pool buffers. -- **Decimals** — `swapAmount` and human amounts are not raw base units. Fetch token decimals from `tokenGetTokens` (or onchain) before building `TokenAmount`. -- **Chain scope** — `chains` is the full intersection of Balancer V3 deployments and Base MCP's `send_calls` support: base, ethereum, arbitrum, optimism, avalanche. The same read → SDK → `send_calls` flow applies to all five — change `chainId` / the `chain` string and let `buildCall` resolve that chain's Router. Balancer V3 also runs on Gnosis, Sonic, HyperEVM, Plasma, and Monad, but Base MCP can't route `send_calls` there, so they're out of scope; Polygon and BSC are the reverse (Base MCP supports them, V3 isn't deployed). diff --git a/docs/agents/skills/plugins/bankr.md b/docs/agents/skills/plugins/bankr.md deleted file mode 100644 index 267b291b5..000000000 --- a/docs/agents/skills/plugins/bankr.md +++ /dev/null @@ -1,247 +0,0 @@ ---- -title: "Bankr Plugin" -description: "Discover and buy newly launched tokens on Bankr." -tags: [token-launches, trading, memecoins, discovery] -name: bankr -version: 0.2.0 -integration: http-api -chains: [base] -requires: - shell: none - allowlist: [api.bankr.bot] - externalMcp: null - cliPackage: null -auth: none -risk: [low-liquidity, irreversible] ---- - -# Bankr Plugin - -> [!IMPORTANT] -> Complete the short Base MCP onboarding flow defined in `SKILL.md` before calling any Bankr flow.

Always disambiguate by `tokenAddress` and confirm with the user before swapping. -- **No endorsement.** The Bankr feed is unfiltered. The Base MCP and this plugin do not vet, endorse, or audit listed tokens — many are low-liquidity, short-lived, or meme tokens. Mention this once before the first buy of a session. -- **Adversarial metadata.** Token names, symbols, deployer handles, and website URLs are user-supplied and can be misleading or impersonate legitimate projects.

By collecting telemetry data, we can: - -- **Monitor Wallet Operation Success**: Track which wallet operations (signing, connecting, transactions) are most reliable and identify failure patterns -- **Data-Informed Improvements**: Help our engineering team generate insights that drive future wallet enhancements and reliability improvements -- **Proactive Issue Detection**: Quickly detect issues with new SDK releases or wallet operations through operational metrics and error monitoring - -## What Data Will Be Collected? - -Telemetry data is completely anonymous and focused on functional metrics.

- - -### Best Practices - -To provide the best possible user experience when integrating "Sign in With Base," consider the following guidelines: - -- **Offer Value for Sign-in**: Clearly communicate the benefits of signing in. Users should understand why they are being asked to sign in, such as to personalize their experience, access premium features, or synchronize data across devices. - -- **Prominently Display the Button**: Make the "Sign in With Base" button easily discoverable. It should be no smaller than other sign-in options and should not require users to scroll to find it. - -- **Consistent Placement**: Place the "Sign in With Base" button in a consistent and logical location on your sign-in and account creation screens. - -### Design & Brand Guidelines - -The "Sign in With Base" button should be easily recognizable and consistent across all platforms. Adhering to these design guidelines ensures a familiar and trusted experience for users. - -#### Button Appearance - -The "Sign in With Base" button has two key components: - -1. **The Base logo is a blue square** - - The square never changes shades of blue, it's always `#0000FF` - - In dark mode, the square changes color to pure white `#FFFFFF` - -2. **The "Sign in with Base" text** - - Always use "Sign in with Base" unless there's an explicit "Sign in" heading prior - - Use "Base Sans" where possible, otherwise [create a custom button](#creating-a-custom-button) - -Following are some DOs and DON'Ts for the Base branding: - -#### DO -- Leave at least 8pt of padding in-between the base square and "Sign in with Base", if creating a custom button -- Use base blue on a white/light background -- Use the all-white lockup if on a black/dark background -- Use "Sign in with Base" (including "Sign in") unless "Sign in" is present as a heading on the screen - -#### DON'T -- Use gradients for the logo -- Change the corner radius of the logo -- Change the color of the Base Square -- Use Base Blue on a dark background - -Base offers the following out of the box components: - -

- -### Design & Brand Guidelines - -The "Base Pay" button should be easily recognizable and consistent across all platforms. Adhering to these design guidelines ensures a familiar and trusted experience for users. - -#### Button Appearance - -The "Base Pay" button always uses a combination mark. It never uses typography or text to write "Base Pay" or "base pay". - -Following are some DOs and DON'Ts for the Base branding: - -#### DO -- Always use the "Base Pay" combination mark -- Use the all white version of the combination mark on dark backgrounds -- Use at least 1X the height of the button for padding. If the mark is 24px high, pad the button with at least 24px on all sides - -#### DON'T -- Write "Base Pay" or "base pay" using fonts or text -- Change the combination mark in any way -- Change the color of the Base Square -- Use Base Blue on a dark background - -### Examples - -
