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.

{
  "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",
        "--allow-write"
      ]
    }
  }
