Getting started

Setup

Create .env file with your postgres db vars

"DB_HOST": "localhost",
"DB_PORT": "5432",
"DB_NAME": "<table>",
"DB_USER": "<user>",
"DB_PASSWORD": "<password>"

1. `` npm i ``

1. `` npm run build ``

1. Ensure your server script is executable:

4. Ensure the shebang line at the top of your compiled server.js:

Setup cursor mcp server:

In cursor go to: Settings > MCP Servers

{
  "mcpServers": {
    "postgres": {
      "command": "node",
      "args": ["./dist/server.js"],
      "env": {
        "DB_HOST": "localhost",
        "DB_PORT": "5432",
        "DB_NAME": "<db_name>",
        "DB_USER": "<db_user>",
        "DB_PASSWORD": "<password>"
      }
    }
  }
}

To test run in terminal:

echo '{"jsonrpc": "2.0", "id": 1, "method": "tools/list", "params": {}}' | node dist/server.js

Once you add it in cursor settings, restart cursor and then reopen and make sure it loads
