原始README
PostgreSQL
A Model Context Protocol server that provides read-only access to PostgreSQL databases. This server enables LLMs to inspect database schemas and execute read-only queries.
Components
Tools
- query
- Execute read-only SQL queries against the connected database
- Input:
sql(string): The SQL query to execute - All queries are executed within a READ ONLY transaction
Resources
The server provides schema information for each table in the database:
- Table Schemas (
postgres://<host>/<table>/schema)- JSON schema information for each table
- Includes column names and data types
- Automatically discovered from database metadata
Usage with Claude Desktop
To use this server with the Claude Desktop app, add the following configuration to the "mcpServers" section of your claude_desktop_config.json:
Docker
- when running docker on macos, use host.docker.internal if the server is running on the host network (eg localhost)
- username/password can be added to the postgresql url with
postgresql://user:password@host:port/db-name
