Overview

Langfuse Prompt Management MCP Server is a server that allows users to access and manage Langfuse prompts through the Model Context Protocol (MCP).

To use the server, you need to build it using npm, configure it with your Langfuse API keys, and add it to your MCP clients like Claude Desktop or Cursor.

  • Implements MCP Prompts specification for prompt discovery and retrieval. - Provides endpoints to list and get specific prompts. - Exports tools for compatibility with other MCP clients.
  1. Managing and retrieving prompts for AI applications.
  2. Integrating prompt management into various MCP clients.
  3. Facilitating prompt discovery for developers.

Add to your AI client

Use these steps to connect Langfuse Prompt Management MCP Server in Cursor, Claude, VS Code, and other MCP-compatible apps. The same JSON appears in the Use with menu above for one-click copy.

Cursor

Add this to your .cursor/mcp.json file in your project root, then restart Cursor.

.cursor/mcp.json

{
  "mcpServers": {

      ]
    }
  }
}

Claude Desktop

Add this server entry to the mcpServers object in your Claude Desktop config, then restart the app.

~/Library/Application Support/Claude/claude_desktop_config.json (macOS) or %APPDATA%\Claude\claude_desktop_config.json (Windows)

{
  "mcpServers": {
