The Open Source Drop Lens

Postgres MCP connects your AI assistant to Aurora PostgreSQL databases. Run queries, inspect schemas, list tables. Setup is a connection string in your MCP config.
Aurora Postgres pricing is usage-based. The MCP is free. AWS Labs maintains it with read-only query defaults.
Essential if you are doing any development against Aurora Postgres. Having your AI understand your schema changes the conversation entirely. The catch: optimized for Aurora Postgres, not vanilla PostgreSQL. It works with standard Postgres, but Aurora-specific tooling is the focus.
