Claude Code, in conjunction with MCP, can now propose PostgreSQL migrations by inspecting application code and identifying failing queries. However, it is crucial to separate the investigation and proposal capabilities from the execution of these migrations. A recommended approach involves using read-only identities for investigation, exposing specific tools for schema inspection and migration planning, and ensuring that mutation tools remain separate. The migration plan should be validated against the current schema and runtime state before being approved and executed by a controlled runner with a short-lived identity, with revalidation and durable receipts ensuring safety and accountability.
