Error message

Remote MCP server returned an HTTP error

What it means

Remote MCP forwarding: the upstream server answered tools/call with a non-2xx HTTP status. The connection health is marked error and a 502 mcp_remote_status wraps the upstream status, request id, and execution details — the failure originates in the remote server, not the gateway or the agent's request shape.
