常见问题

What transport does PostgreSQL MCP Server use?

The server uses stdio transport (MCP protocol over standard input/output).

What are the runtime requirements?

Python 3.8+ and a PostgreSQL server (local or remote) with the `uv` package runner (recommended) or `pip`.

How are database credentials configured?

Via a `.env` file with `POSTGRES_HOST`, `POSTGRES_PORT`, `POSTGRES_DB`, `POSTGRES_USER`, and `POSTGRES_PASSWORD`, or directly in the client config's `env` block.
