Tool Registration

Registers a website's functions as typed, callable tools via registerTool so browser AI agents can invoke them directly.

Browser MCP Transport

Bridges in-page tools to MCP clients over an in-browser transport, with no backend MCP server to rebuild.

Framework Hooks

Provides React hooks and a TypeScript SDK to expose app functionality as WebMCP tools, SSR- and Strict-Mode-safe.
