Session-scoped: start once, run your automation, then stop. Requires a paid Kernel plan. +- `manage_search` - Create web searches, retrieve retained searches, and discover provider capabilities and native option schemas. The `search` toolset is exposed only after the current credential successfully reads a valid `GET /search/providers` response; the API gates that endpoint with the same organization flag as search execution. Access is rechecked on every MCP request, including tool calls, and errors or malformed responses hide the tool. Toolset configuration cannot bypass this check. Search creation is billable and is not automatically retried. Deferred content retrieval is not exposed. - `manage_extensions` - List and delete uploaded browser extensions. - `manage_apps` - List/search apps, invoke actions, get/list/delete deployments, and get invocation results. - `manage_auth_connections` - Create, list, get, update, delete, login, submit, inspect timelines, and wait for managed-auth connections in every client. Supports health-check and automatic re-auth settings, managed-auth browser configuration, and canonical interaction-bound field/choice submissions. Use domain-filtered `list` for discovery. App-capable clients additionally receive `open_auth_login`; the programmatic actions remain available there too. diff --git a/src/app/[transport]/route.test.ts b/src/app/[transport]/route.test.ts index 5026b8a..f53dd83 100644 --- a/src/app/[transport]/route.test.ts +++ b/src/app/[transport]/route.test.ts @@ -179,8 +179,12 @@ describe("connection scope failures through the handler", () => { }); }); -describe("vault entitlement routing", () => { - function installKernelResponses(entitlements: (token: string) => Response) { +describe("capability routing", () => { + function installKernelResponses( + entitlements: (token: string) => Response, + search: (token: string) => Response = () => + Response.json({}, { status: 404 }), + ) { const paths: string[] = []; defaultMcpDependencies.createKernelClient = (token) => new Kernel({ @@ -205,6 +209,7 @@ describe("vault entitlement routing", () => { }, }); if (path === "/org/entitlements") return entitlements(token); + if (path === "/search/providers") return search(token); throw new Error(`Unexpected API request: ${path}`); }, }); @@ -258,13 +263,75 @@ describe("vault entitlement routing", () => { expect(paths).toEqual([ "/auth/context", "/org/entitlements", + "/search/providers", "/auth/context", "/org/entitlements", + "/search/providers", "/auth/context", "/org/entitlements", + "/search/providers", ]); }); + test("gates search discovery and direct calls per caller, including revocation", async () => { + let enabled = true; + const paths = installKernelResponses( + () => Response.json({ features: { vaults: { enabled: true } } }), + (token) => + token === "sk_allowed" && enabled + ?
