Postgres MCP

🔌 Native MCP server for PostgreSQL - reads credentials from .env at runtime with flexible key mapping, configurable tool selection, and read-only mode by default . It runs locally over stdio via the published package.

People who work with postgres, security and sql and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in JavaScript.

Claude Code

claude mcp add edelciomolina-postgres-mcp -- npx -y @edelciomolina/postgres-mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "edelciomolina-postgres-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@edelciomolina/postgres-mcp"
      ]
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Using another client? Same JSON, different key
