How do I connect the Langfuse MCP server to Claude?
A local package is listed as langfuse-mcp. Use the publisher's installation instructions for its complete command, arguments and authentication settings. A package name alone is not a complete Claude Desktop or Claude Code configuration.
The registry also lists these authentication or required environment fields: LANGFUSE_PUBLIC_KEY (secret), LANGFUSE_SECRET_KEY (secret). Follow the publisher's guidance on which ones your authentication method needs, and keep secrets out of shared files.
Does the Langfuse MCP server work with ChatGPT?
This listing includes a local package but no hosted endpoint. ChatGPT needs a compatible remote server; check the publisher's current instructions for a hosted option. The registry entry alone does not establish whether the vendor offers one.
How do I add it to Cursor?
Use the publisher's Cursor or local MCP instructions to fill in .cursor/mcp.json. Include its complete arguments and required environment fields; the package listing above is not a ready-to-run configuration.
