Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "postgres": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-pg-server"
      ]
    }
  }
}

Run this in your terminal

claude mcp add postgres -- npx -y mcp-pg-server

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "postgres": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-pg-server"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Common questions

Is Postgres safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 3 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

mcp-server-postgres

Query PostgreSQL, inspect schemas, and explain queries from your AI assistant. A daily-driver MCP for local and dev Postgres — same belt as docker and sqlite servers, not an enterprise DBA suite.

DATABASE_URL=postgres://user:pass@localhost:5432/mydb npx mcp-pg-server

Works with Claude Desktop, Cursor, VS Code Copilot, and any MCP client. Connects via DATABASE_URL or per-call connectionString.

Why

Postgres is the default for most new backends, local dev stacks, and agent workflows that need a real SQL database. You already run it in Docker or on localhost — this server lets your assistant query it, read schemas, and explain plans without leaving the IDE. Read-only by default so exploration stays safe; opt into writes when you need them.

Tools

Tool	What it does
`query`	Execute SQL (SELECT, WITH, EXPLAIN, SHOW, ANALYZE). Returns a text table.
`schema`	Tables in a schema (default `public`) with columns and approximate row counts
`table_info`	One table: columns, types, null/default, PK, exact row count
`explain`	EXPLAIN (FORMAT TEXT), optional ANALYZE
`list_schemas`	List non-system schemas

Quick Start

Cursor

Add to .cursor/mcp.json:

"mcpServers": { "postgres": { "command": "npx", "args": ["mcp-pg-server"], "env": { "DATABASE_URL": "postgres://user:pass@localhost:5432/mydb" } } } }

Claude Desktop

Add to claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/claude_desktop_config.json):

"mcpServers": { "postgres": { "command": "npx", "args": ["mcp-pg-server"], "env": { "DATABASE_URL": "postgres://user:pass@localhost:5432/mydb" } } } }

VS Code

Configure the MCP server in your VS Code settings to run npx mcp-pg-server with DATABASE_URL set.

Example prompts

"Show me the schema of the public tables"
"Query users: SELECT * FROM users LIMIT 10"
"Explain this join query"
"What schemas exist in this database?"
"How many rows are in the orders table?"

Safety

Read-only by default. The query tool accepts only SELECT, WITH, EXPLAIN, SHOW, and ANALYZE in readonly mode. Set readonly=false to enable INSERT, UPDATE, DELETE, and DDL.

Pass connectionString on any tool to override DATABASE_URL for a single call.

Development

npm install
