Write Operations

AGE-MCP-Server prohibits write operations by default for safety. If you want to enable write operations, you can use the --allow-write flag.

python -m pip install age_mcp_server

Usage with Claude

on macOS claude_desktop_config.json is located in ~/Library/Application Support/Claude/.
on Windows You need to create a new claude_desktop_config.json under %APPDATA%\Claude.
Homebrew on macOS

Homebrew installs age_mcp_server into $PATH.

{
  "mcpServers": {
    "age_manager": {
      "command": "age_mcp_server",
      "args": [
        "--pg-con-str",
        "host=your_server.postgres.database.azure.com port=5432 dbname=postgres user=your_username password=your_password",
      ]
    }
  }
}

uv / Pyhon venv

On macOS:

{
  "mcpServers": {
    "age_manager": {
      "command": "/Users/your_username/.local/bin/uv",
      "args": [
        "--directory",
        "/path/to/your_project",
        "run",
        "age_mcp_server",
        "--pg-con-str",
        "host=your_server.postgres.database.azure.com port=5432 dbname=postgres user=your_username password=your_password",
      ]
    }
  }
}

On Windows:

{
  "mcpServers": {
    "age_manager": {
      "command": "C:\\Users\\USER\\.local\\bin\\uv.exe",
      "args": [
        "--directory",
        "C:\\path\\to\\your_project",
        "run",
        "age_mcp_server",
        "--pg-con-str",
        "host=your_server.postgres.database.azure.com port=5432 dbname=postgres user=your_username password=your_password",
      ]
    }
  }
}

If you need to hide the password or to use Entra ID, you can set --pg-con-str as follows.

{
  "mcpServers": {
    "age_manager": {
        ...
        "--pg-con-str",
        "host=your_server.postgres.database.azure.com port=5432 dbname=postgres user=your_username",
        ...
      ]
    }
  }
}

And, you need to set PGPASSWORD env variable, or to install Azure CLI and sign into Azure with your Azure account.

After saving claude_desktop_config.json, start Claude Desktop Client.

            "args": [
                "--directory",
                "/path/to/your_project",
                "run",

                "--debug"
            ]
            }
        }
    }
