Which app do you use?

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": {
    "database-postgres": {
      "command": "npx",
      "args": [
        "-y",
        "@database-mcp/postgres"
      ],
      "env": {
        "POSTGRES_HOST": "your-value",
        "POSTGRES_USER": "your-value",
        "POSTGRES_PASSWORD": "your-value",
        "POSTGRES_DATABASE": "your-value"
      }
    }
  }
}

Run this in your terminal

claude mcp add database-postgres --env POSTGRES_HOST=your-value --env POSTGRES_USER=your-value --env POSTGRES_PASSWORD=your-value --env POSTGRES_DATABASE=your-value -- npx -y @database-mcp/postgres

Fill in the empty values before running it.

Open in Cursor

Or copy the settings yourself

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

{
  "mcpServers": {
    "database-postgres": {
      "command": "npx",
      "args": [
        "-y",
        "@database-mcp/postgres"
      ],
      "env": {
        "POSTGRES_HOST": "your-value",
        "POSTGRES_USER": "your-value",
        "POSTGRES_PASSWORD": "your-value",
        "POSTGRES_DATABASE": "your-value"
      }
    }
  }
}

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

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "database-postgres": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@database-mcp/postgres"
      ],
      "env": {
        "POSTGRES_HOST": "your-value",
        "POSTGRES_USER": "your-value",
        "POSTGRES_PASSWORD": "your-value",
        "POSTGRES_DATABASE": "your-value"
      }
    }
  }
}

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.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

Values you fill in

POSTGRES_HOST required env
Database host
POSTGRES_USER required env
Database user (a read-only user is recommended)
POSTGRES_PASSWORD secret env
Database password (or use POSTGRES_PASSWORD_FILE)
POSTGRES_DATABASE required env
Database name

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Common questions

Is Database MCP 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?

You need to fill in: POSTGRES_HOST, POSTGRES_USER, POSTGRES_PASSWORD, POSTGRES_DATABASE

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 (0.5.0) reached the registry 20 days 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, Python (uv), Rust on your computer.

What can I use instead?

README from the maker

Copied from the maker’s repo as written. PopNx MCP has not reviewed or endorsed it. HTML, images and scripts are removed. Links lead off this site.

database-mcp

MCP servers that give AI clients safe, structured access to SQL databases.

One installable package per database engine, in TypeScript (npm), Python (PyPI), and Rust (crates.io). Every package exposes the same minimal two-tool surface, execute_sql and search_objects, with guardrails on by default: read-only mode, row caps, and statement timeouts.

Packages

Engine	TypeScript (npm)	Python (PyPI)	Rust (crates.io)
SQLite	`@database-mcp/sqlite`	`database-mcp-sqlite`	`database-mcp-rs-sqlite`
libSQL	`@database-mcp/libsql`	`database-mcp-libsql`	`database-mcp-rs-libsql`
MySQL	`@database-mcp/mysql`	`database-mcp-mysql`	`database-mcp-rs-mysql`
MariaDB	`@database-mcp/mariadb`	`database-mcp-mariadb`	`database-mcp-rs-mariadb`
Postgres	`@database-mcp/postgres`	`database-mcp-postgres`	`database-mcp-rs-postgres`

All three lines are published and pass the same language-agnostic conformance suite against real databases in CI, so behavior is identical regardless of language. Every engine is also listed on the MCP Registry with all three install options: npm, PyPI, and cargo.

Rust crates are named database-mcp-rs- because the plain names are taken on crates.io; the command each one installs is still database-mcp- . Go is planned.

Design principles

Two tools, no more. A tiny tool surface keeps the model's context window clean. search_objects progressively discloses schema: call it with no arguments to list tables, with a table name to get columns, indexes, and foreign keys.
Safe by default. Read-only mode is enforced in two layers: a conservative SQL guard, plus a session-level read-only setting in the database itself. Rows are capped (default 1000) and statements time out (default 30s).
Configured at launch, never via chat. Connection details come from flags, a YAML config file, or environment variables. Credentials are never accepted through a tool call.
Secrets never appear in logs. Passwords live in non-printable secret types, DSNs are sanitized before logging, and a redaction filter guards the log boundary.

Quick start

Pick your engine's package; each README has the full config surface. SQLite via npm:

"mcpServers": { "sqlite": { "command": "npx", "args": ["-y", "@database-mcp/sqlite", "--dsn", "/absolute/path/to/database.db"] } } }

Or via PyPI: use "command": "uvx" and "args": ["database-mcp-sqlite", "--dsn", "/absolute/path/to/database.db"].

Or as a native binary, with no Node or Python runtime: run cargo install database-mcp-rs-sqlite, then use "command": "database-mcp-sqlite" with the same args minus the package name.

Flags, environment variables, and YAML config are identical across all three lines.

Networked engines take credentials from the environment (MYSQL_*, MARIADB_*, POSTGRES_*/DATABASE_URL, LIBSQL_URL/LIBSQL_AUTH_TOKEN), *_FILE mounted secrets, or a YAML file via --config. Never from a chat prompt.
