This is an MCP endpoint, not a website

There is nothing to browse here. The address belongs in the connector settings of an MCP client, which talks to it over JSON-RPC.

Endpoint URL

https://demo.toolmesh.io/mcp

Authentication

Required. The client is sent through OAuth on first connect; an API key in the Authorization header works too.

Where to paste it

Seeing Method not allowed instead of this page? That is the endpoint working: it answers POST with JSON-RPC, not GET with HTML.
