xint-sse-transport-handshake-fails-use-http-streamable

xint MCP server supports both SSE (/sse) and HTTP Streamable (/mcp) transports, but claude-code’s MCP client fails the SSE handshake for this specific server. Re-registering as type: http pointing to /mcp resolves connectivity immediately. This applies to both /home/claude/.claude.json and /root/.claude.json (dual-config rule). Symptom: server shows as failed in claude mcp list despite the process running and returning HTTP 200.
