PostgreSQLMCP Server
Summary
Read-only PostgreSQL access with automatic schema inspection — the reference MCP server for Postgres.
Features

- Automatic schema inspection for every table
- Single-argument setup with a connection string
Installation

Description
The reference PostgreSQL MCP server gives an assistant read-only access to a database, along with the schema information it needs to write correct queries.
What it does
- Read-only query execution. Every statement runs inside a read-only transaction, so an assistant cannot modify data even if it decides to try.
- Schema resources. Each table is exposed as a resource with its column names and types, so the model works from the actual schema rather than inferring one from table names.
Why the read-only constraint is the point
Giving a language model write access to a production database is a decision that deserves more thought than a config file entry. This server removes the question entirely, which makes it a sensible default for analysis, debugging, and answering questions about data.
Setup
One argument — the connection string — and you are running: npx -y @modelcontextprotocol/server-postgres postgresql://host/db. For write access or broader database support, DBHub and vendor-specific servers are better choices.
