Note

Medium Risk
Adds proxy routing and executable custom WebMCP tooling plus a breaking reshaping of WebMCP Tool response types; pool acquire/release behavior changes when profiles are used.

Overview
Release 0.112.0 bumps the package and adds several API surface updates from the OpenAPI sync (172 configured endpoints).

WebMCP custom tools are the largest client change: client.browsers.webmcp.custom_tools supports listing, registering (namespaced JS batches), and removing custom tools. list_tools accepts exclude_custom, and tool snapshots use a nested tool (ToolMetadata) with MCP/WebMCP-aligned annotations instead of flat name/description/schema fields on Tool.

Browser pools can pass an optional profile on acquire; release docs note that browsers acquired with a profile are always torn down on release, even when reuse is true.

Network config gains proxy_routes (hostname patterns → proxy) on browser session network types. Telemetry archived event reads accept a type filter (with category), and event models add iframe/worker target types, updated monitor_disconnected semantics, and destination_route_unavailable on proxy errors. Org entitlements expose a search feature flag.
