Insurance MCP server scaffold (FastMCP 3.2 + Prefab-style UI payloads)

This scaffold implements an AI-agent backend for insurance recommendation with:

• Contract recommendation tool
• Horizontal carousel UI payload for contract cards
• Structured contract draft generation
• Validation for missing or invalid user data
• Electronic signature workflow with human approval
• Persist signed JSON contract to database

Important assumption The request mentioned Prefab integration for beautiful UI. Because the exact Prefab SDK / component contract is not specified here, the scaffold uses a Prefab adapter interface + generic UI JSON schema that your frontend/agent host can map to Prefab components.

Tools included

1. recommend_contracts
2. validate_profile
3. generate_contract_draft
4. request_missing_fields
5. submit_signature_for_approval
6. approve_and_persist_contract

Notes about FastMCP 3.2

The exact import path / decorator names can differ slightly by installation packaging. If your environment exposes a different API surface, update the import in app/server.py and keep the tool function signatures + return shapes unchanged.
