FAQ from Maven Repository MCP Server
What transport protocols does the server support?
The server supports stdio (default) and SSE (Server-Sent Events) protocols. Use npm run start:stdio or npm run start:sse to select.
How can I change the SSE port?
When running in SSE mode, use the --port flag, for example node dist/index.js sse --port 8080.
What rate limiting is implemented?
The server enforces a minimum of 3 seconds between requests, adds a random 2-6 second delay, and automatically retries with exponential backoff when it receives 403 errors.
What are the timeout settings?
Default request timeout is 30 seconds, Maven Central POM requests timeout after 15 seconds, and a maximum of 3 retry attempts are made for failed requests.
How do I enable debug mode?
Set the environment variable DEBUG=mvn-repository-mcp-server before starting the server, for example DEBUG=mvn-repository-mcp-server npm start.
