 "page_title": "How to let Claude Code browse the catalog and run read-only SQL with Open Lakehouse Compute Fabric",
 "summary": "Connect Claude Code to the OLCF MCP endpoint to explore tables, follow lineage and query safely.",
 "who": "An analyst who wants an AI coding agent to answer questions about the lakehouse without giving it write access.",
 "problem": "Answering questions about tables and lineage means manual catalog browsing and hand-written queries.",
 "outcome": "Claude Code lists catalog assets, follows lineage and returns read-only SQL results, limited to the permissions of the token's creator.",
 "steps": [
  "Start the OLCF platform from the quickstart.",
  "Create an MCP token for your own user in the OLCF console.",
  "Add the OLCF MCP endpoint to Claude Code using that token.",
  "Ask Claude Code to list the sample tables and run a read-only SQL count on one of them."
 ],
 "agent_prompt": "Use the open-lakehouse-compute-fabric repo (jddevtime/open-lakehouse-compute-fabric) through its MCP endpoint. List the catalog assets in the sample Retail lakehouse, then run one read-only SQL count on <table name> and return the result. Verify that the query was rejected if you ask for any write statement.",

  "For the Fabric extension: a Fabric tenant you control, the olcf_fabric wheel in a Fabric Environment, and Entra and network setup"
