Chat with Database

Summary

The Chat with Database Agent answers questions about your data in plain English. It introspects the schema, writes the SQL, runs it read-only, and explains the results. Reach for it to give non-SQL users a safe way to query a database, or to prototype analytics without hand-writing queries.

Customization

• Swap the database. Replace the client in lib/db.ts with Postgres or MySQL.
• Allow writes (carefully). The run_query tool blocks non-SELECT SQL by default — relax that only behind explicit confirmation.
• Add row limits. Cap result size in run_query to protect against huge scans.
• Swap the model. Edit agent/agent.ts.
