A zero-config dev panel for WebMCP: lists the tools a page registers, auto-builds a form from each inputSchema, invokes them, and shows the result — pairs with @mcptrail/webmcp-highlight to see what changed.

React hooks that register/unregister WebMCP tools with component lifecycle — the agent only sees tools for what's currently on screen.

Client-side drift detection for a WebMCP toolset: hash the tools a page exposes to agents, freeze a baseline, and fire onDrift when they change.

Expose a page's WebMCP tools as a real MCP server: an in-page JSON-RPC handler (initialize/tools/list/tools/call/ping) over a pluggable transport.

Client-side human-in-the-loop for WebMCP: gate agent tool calls behind an approval policy (auto/confirm/deny), with a built-in modal or your own approver.

Zero-config highlighting of the DOM changes an agent's WebMCP tool calls make — overlay rings, a change timeline, and off-screen reveal. Framework-agnostic core + React binding.

Type-safe defineTool for WebMCP: infer execute() arg types from a JSON Schema, with optional runtime validation. Zero deps.

A navigator.modelContext polyfill for WebMCP: installs a spec-faithful shim only when the browser lacks it, so tools register on any browser.

Test WebMCP tools without a flagged Chrome or a live model: a mock navigator.modelContext plus a driver to list, validate-args, invoke, and snapshot the toolset.
