Follow each phase in order; later phases depend on artifacts (app_id, schema, RLS policies) produced by earlier ones. > **Convention:** every JSON body below is the argument object for the tool named in its **Tool:** header. When the header reads `manage_schema` with `action: "apply"`, include `"action": "apply"` alongside the other fields when you make the call. --- ## Phase 1: Create the App Use `init_app` to provision an isolated backend with its own database and auto-generated REST API. **Tool:** `init_app` ```json { "name": "my-blog" } ``` **Returns:** ```json { "app_id": "app_abc123", "api_base": "https://api.butterbase.ai/v1/app_abc123" } ``` **Important:** Save `app_id` and `api_base` — every subsequent tool call requires `app_id`. ### Optional: Generate a Service API Key If the user needs programmatic access (CI/CD pipelines, server-to-server calls, admin scripts), generate a service key now. **Tool:** `manage_auth_config` with `action: "generate_service_key"` ```json { "name": "Production Deploy Key" } ``` > ⚠️ The ful...
