newswhip-developer-hub

NewsWhip serves a live, reachable MCP endpoint from its own developer host at https://developer.newswhip.com/mcp. A GET returns "This URL can only be accessed with a MCP client" (HTTP 200) and a JSON-RPC POST returns a well-formed JSON-RPC error envelope — both `initialize` and `tools/list` answer {"jsonrpc":"2.0","error":{"code":-32001,"message":"Authorization required"},"id":null} with HTTP 401. The endpoint is therefore real and provider-hosted, but its tool list is auth-gated and could not be enumerated anonymously. No WWW-Authenticate header is returned and no /.well-known/oauth-protected-resource or /.well-known/oauth-authorization-server is served (all 404), so the authorization flow is not discoverable either — a client cannot bootstrap auth from the endpoint alone.
