 "summary": "Ask questions about a PostgreSQL, MySQL, SQL Server, Oracle, or Dameng database with privacy protection on.",
 "who": "A data analyst who needs answers from a company database that contains phone numbers, emails, or ID numbers.",
 "problem": "Sending raw database rows with personal data to a cloud LLM exposes that data.",
 "outcome": "Baize queries the database through the RDBMS MCP server, redacts personal fields before the LLM sees them, and restores the original text in its answers.",
 "steps": [
  "`pip install -r requirements-data.txt`",
  "For SQL Server only: install Microsoft ODBC Driver 18 for SQL Server at the system level, because `pyodbc` alone is not enough.",
  "Add your database connection to the MCP server settings; the README names the MCP protocol but does not show the exact config format, so check the project documentation. (inferred, check the README)",
  "`baize`",
  "At the `>>> Decree:` prompt, type `/privacy` to confirm privacy protection is on, then ask your question about the database."
 ],
 "agent_prompt": "Using the Baize CLI from the Xu123-Bob/Baize repo with privacy protection on, ask it to count rows in <table-name> of <database-name> and summarize the result. Expected output: a row count and a short summary with no raw personal values. Verify that no phone number or email appears in the LLM-facing prompt log.",
