DryRun — Offline PostgreSQL MCP (No DB Creds)

Main

• Adopt the “schema file” model: one person dumps/imports a snapshot, everyone else runs dryrun lint offline as shown in the README demo.

• Use the MCP server to give agents schema intelligence without credentials; README shows claude mcp add dryrun -- dryrun mcp-serve.

• Treat lint output as actionable checklists: README includes example warnings/errors and suggested fixes (PKs, timestamptz, FK indexes).

Source-backed notes

• README states dryrun is both a CLI tool and an MCP server, intentionally separated.
• README explains the MCP server reads snapshots and exposes tools over stdio or SSE without a live DB connection.
• README includes offline demo output with violations and fixes, and documents dryrun mcp-serve usage.

FAQ

• Does it need prod DB access for the MCP server?: No — README emphasizes snapshots so credentials stay with DBAs.
• How do I start the MCP server?: Use dryrun mcp-serve and add it via your client config (README shows Claude).
• Can it lint offline?: Yes — README demonstrates dryrun lint working entirely from a schema file.
