Fixed

  • Microsoft Copilot Studio could not finalize an MCP connection or list tools. Verified against a Copilot-compatible reference server (Microsoft Learn Docs MCP): the streamable endpoint must return SSE-framed responses (Content-Type: text/event-stream) on POST and 405 on a bare GET. AnythingMCP returned application/json and 401 respectively. Now: responses are SSE-framed by default (set MCP_STREAMABLE_JSON_RESPONSE=true for the old behaviour) and a GET to the MCP endpoint returns the transport's 405 instead of an auth 401. Spec-compliant clients (e.g. Claude) are unaffected.
