xint-sse-transport-incompatible-with-claude-code-mcp-client

claude-code’s MCP client fails the SSE handshake for the xint server when registered as type: sse at /sse endpoint, even though the server supports both transports. Re-registering as type: http at /mcp resolves the issue immediately. Both /home/claude/.claude.json and /root/.claude.json must be updated simultaneously to maintain dual-config parity.
