MCP Server for Langfuse Prompts
The Langfuse Model Context Protocol (MCP) Server enables AI assistants and agents to interact with your Prompt Management system. The server is built directly into Langfuse at /api/public/mcp (streamableHttp), no external setup or build steps required.
The MCP Reference is the canonical source for current Langfuse MCP servers, setup snippets, tools, input schemas, and generated request examples.
Setup
See the MCP Server setup guide for complete instructions on authentication and client configuration.
Example Workflows
Create a New Prompt
Ask your AI agent:
"Create a new text prompt called 'customer-email' with a friendly greeting template that includes name and product variables. Tag it as 'draft' and add a production label."
The agent will use createTextPrompt to create the prompt version.
Promote a Prompt to Production
"Move the production label from version 2 to version 3 of the customer-email prompt"
The agent will use updatePromptLabels to update the label assignment.
Iterate on a Chat Prompt
"Create a new version of the code-review prompt with improved system instructions and add an example assistant message showing the review format"
The agent will use createChatPrompt to create a new version with enhanced content after having fetched the prompt with getPrompt.
