Hosted MCP Server for Langfuse Prompt Management

Langfuse now includes a native Model Context Protocol (MCP) server with write capabilities, enabling AI agents to fetch and update prompts directly.

The native MCP server is available at /api/public/mcp and provides five tools for comprehensive prompt management:

Read Operations:

• getPrompt – Fetch specific prompts by name, label, or version
• listPrompts – Browse all prompts with filtering and pagination

Write Operations:

• createTextPrompt – Create new text prompt versions
• createChatPrompt – Create new chat prompt versions (OpenAI-style messages)
• updatePromptLabels – Manage labels across prompt versions

The native server uses a stateless architecture built directly into the platform with BasicAuth credentials, replacing the previous node package version. Includes complete setup guide and prompt-specific workflows documentation.
