CopilotKit added per-tool WebMCP support so browser agents can discover existing frontend actions.

Why it matters

Embedded assistants and browser agents can reuse application operations.

A closer look

Tools register with component lifecycle and carry annotations. Unsupported and server-rendered environments fall back gracefully.

Who this is for

Frontend and browser-agent developers
