Integrations

  • Provides read-only access to PostgreSQL databases, allowing LLMs to inspect database schemas and execute read-only queries against connected PostgreSQL databases

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

Configuration

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
{ "mcpServers": { "postgres": { "command": "docker", "args": [ "run", "-i", "--rm", "mcp/postgres", "postgresql://host.docker.internal:5432/mydb"] } } }

NPX

{ "mcpServers": { "postgres": { "command": "npx", "args": [ "-y", "@modelcontextprotocol/server-postgres", "postgresql://localhost/mydb" ] } } }

Replace /mydb with your database name.

Usage with VS Code

For quick installation, use one of the one-click install buttons below...

For manual installation, add the following JSON block to your User Settings (JSON) file in VS Code. You can do this by pressing Ctrl + Shift + P and typing Preferences: Open User Settings (JSON).

Optionally, you can add it to a file called .vscode/mcp.json in your workspace. This will allow you to share the configuration with others.

Note that the mcp key is not needed in the .vscode/mcp.json file.

Docker

Note: When using Docker and connecting to a PostgreSQL server on your host machine, use host.docker.internal instead of localhost in the connection URL.

{ "mcp": { "inputs": [ { "type": "promptString", "id": "pg_url", "description": "PostgreSQL URL (e.g. postgresql://user:pass@host.docker.internal:5432/mydb)" } ], "servers": { "postgres": { "command": "docker", "args": [ "run", "-i", "--rm", "mcp/postgres", "${input:pg_url}" ] } } } }

NPX

{ "mcp": { "inputs": [ { "type": "promptString", "id": "pg_url", "description": "PostgreSQL URL (e.g. postgresql://user:pass@localhost:5432/mydb)" } ], "servers": { "postgres": { "command": "npx", "args": [ "-y", "@modelcontextprotocol/server-postgres", "${input:pg_url}" ] } } } }

Building

Docker:

docker build -t mcp/postgres -f src/postgres/Dockerfile .
