Pinot MCP Server is a Python-based MCP server designed to interact with Apache Pinot. Built on the FastMCP framework, it exposes capabilities to retrieve Pinot metadata (tables, segments, and schemas), execute read-only SQL queries, and view index or column-level metadata from a Pinot cluster. The server is intended to support real-time analytics workflows and is designed to work with Claude Desktop, enabling business users to explore data, craft prompts, and perform metadata-driven analyses directly against Pinot. Configuration is done via a uvicorn-style .env file in the repository root (with an example file) and supports optional OAuth authentication for secure access. It can be run locally with uv --directory . run mcp_pinot/server.py and can be built and deployed as a Docker image. The project also supports DXT desktop extensions packaging to deliver tools to Claude Desktop. All MCP tooling is implemented in the Pinot class (utils/pinot_client.py), and the repository provides quick-start prompts to exercise the MCP server.
