Overview

The Model Context Protocol (MCP) Server for Langfuse Prompt Management allows users to access and manage Langfuse prompts through the Model Context Protocol. It enables prompt discovery and retrieval, implementing the MCP Prompts specification. The server provides features such as listing available prompts with optional cursor-based pagination, and getting specific prompts by transforming Langfuse prompts into MCP prompt objects. It also offers tools to increase compatibility with other MCP clients. The server is a work in progress with some limitations, including only returning prompts with a production label in Langfuse and assuming all arguments are optional without descriptions.

Q&A

What are the main limitations of this MCP server?

Arguments for prompts are assumed optional and lack descriptions, the list operation requires fetching each prompt individually which can be inefficient, and it only returns prompts marked as production, excluding others in Langfuse.

Asked by Gunnar Eriksson · May 20, 2026

What prompts can the server list and retrieve?

The server only returns prompts that have a "production" label in Langfuse. It lists them via /prompts/list with optional cursor pagination, and retrieves a specific prompt via /prompts/get, transforming it into an MCP prompt object.

How do I add mcp-server-langfuse to an MCP client like Claude Desktop?

Build the server with "npm install" and "npm run build", then add it to Claude’s config: set mcpServers.langfuse.command to "node <path>/build/index.js" and provide LANGFUSE_PUBLIC_KEY, LANGFUSE_SECRET_KEY, and LANGFUSE_BASEURL in the env section.
