DataMCP — Secure MCP Gateway for PostgreSQL

Gives AI tools like Cursor and Claude direct access to your PostgreSQL database through MCP with a permission layer in between. You get schema introspection and SQL query execution with configurable read-only, read-write, or per-table access controls. Connection strings are encrypted at rest with AES-256-GCM, queries are validated before execution, and everything hits an audit log. Useful when you want AI to read your schema and run queries during development without granting full database access. Works over streamable HTTP, so it plugs into any MCP client without local setup. Free tier includes one connection and one MCP link.
