Hi @Rablady! I'm so sorry for the extremely late reply — I just noticed this discussion now. I hope you've already figured it out, but just in case it's still helpful, here's a quick guide:

---

If you're using OpenWebUI (Docker Quickstart)

Step 1 — Make sure all containers are fully started (wait ~2-3 min after docker-compose up -d):

docker-compose ps

All services should show Up.

Step 2 — Register the MCP tool in OpenWebUI:

1. Log in as admin → go to Settings → Tools (top menu)
2. Add this URL:

   http://localhost:8003/postgresql-ops
   

   ⚠️ Use port 8003 (MCPO Proxy), not 18003 (MCP Server direct port).

3. Save and enable the tool in your chat.

You can verify the tool is reachable by visiting http://localhost:8003/docs in your browser — it should show a Swagger API page.

If you're using Claude Desktop

Add this to your Claude Desktop config file (claude_desktop_config.json):

{
  "mcpServers": {
    "mcp-postgresql-ops": {
      "command": "uvx",
      "args": ["--python", "3.12", "mcp-postgresql-ops"],
      "env": {
        "POSTGRES_HOST": "127.0.0.1",
        "POSTGRES_PORT": "5432",
        "POSTGRES_USER": "postgres",
        "POSTGRES_PASSWORD": "your_password",
        "POSTGRES_DB": "your_database"
      }
    }
  }
}

Then restart Claude Desktop.
