This pull request enhances the
AgentMCPServerby addressing issues with SSE (Server-Sent Events) transport and improving authentication handling. The most significant changes include patching theFastMCP.sse_appmethod to resolve ASGI errors, introducing middleware for authentication, and updating the routing logic for SSE and messaging endpoints.Improvements to SSE Handling:
FastMCP.sse_appmethod to prevent returning a secondResponseafter the SSE connection completes. This resolves the"Unexpected ASGI message 'http.response.start'"errors and prevents timeouts when chaining agents in server mode. (src/mcp_agent/mcp_server/agent_server.py, src/mcp_agent/mcp_server/agent_server.pyR55-R147)Authentication Enhancements:
AuthenticationMiddleware,AuthContextMiddleware, andRequireAuthMiddlewarewithBearerAuthBackend. This ensures secure handling of SSE and messaging endpoints.

FastMCP.sse_appmethod. (src/mcp_agent/mcp_server/agent_server.py, src/mcp_agent/mcp_server/agent_server.pyL1-R6)
