@hooksense/mcp

The webhook & callback layer,
as an MCP server.

Your agent kicks off an async job, hands it a HookSense callback URL, and calls wait_for_callback — blocking until the webhook lands, signature-verified and decrypted. No polling loops, no burned context, no missed events.

Await the result — never poll for it.

The whole point. One call blocks until the callback arrives, then resumes with the payload.
