Langfuse Prompt Management MCP Server

Features# MCP Prompt

This server implements the MCP Prompts specification for prompt discovery and retrieval.

• prompts/list: List all available prompts
• Optional cursor-based pagination
• Returns prompt names and their required arguments
• prompts/get: Get a specific prompt

Tools

To increase compatibility with other MCP clients, the server exports tools that replicate the functionality of the MCP Prompts.
