Langfuse MCP Overview

avivsinai/langfuse-mcp MCP server exposes Langfuse data and operations to local MCP clients through the Langfuse Python SDK. It supports trace, session, exception, observation, prompt, dataset, annotation queue, score, metrics, and schema workflows, including route-decision analysis. Run it locally with uvx and Langfuse API credentials, using stdio or HTTP deployment as supported by the project. Reach for it when an agent needs focused Langfuse debugging, controlled tool loading, or read-only access rather than the broader hosted native Langfuse MCP surface.
