Prowler Mcp

Models

• ALWAYS: Use MinimalSerializerMixin for responses
• ALWAYS: Implement from_api_response() factory method
• ALWAYS: Use two-tier models (Simplified for lists, Detailed for single items)
• NEVER: Return raw API responses

API Client

• ALWAYS: Use self.api_client singleton
• ALWAYS: Use build_filter_params() for query parameters
• NEVER: Create new httpx clients

Hub/Docs Tools

Use @mcp.tool() decorator directly—no BaseTool or models required.

Quick Reference: New Prowler App Tool

1. Create tool class in prowler_app/tools/ extending BaseTool
2. Create models in prowler_app/models/ using MinimalSerializerMixin
3. Tools auto-register via tool_loader.py

QA Checklist (Prowler App)

• Tool docstrings describe LLM-relevant behavior
• Models use MinimalSerializerMixin
• API responses transformed to simplified models
• Error handling returns {"error": str, "status": "failed"}
• Parameters use Field() with descriptions
• No hardcoded secrets
