Source of truth

The file reference/endpoints.json is the canonical catalog of endpoints — generated by crawling the official documentation at developers.facebook.com/documentation/business-messaging/... and developers.facebook.com/docs/messenger-platform/....

Each tool wraps an endpoint from that catalog. To add support for a new endpoint:

1. Add an entry to reference/endpoints.json

2. Create the tool in src/tools/<product>.ts using graphRequest() from src/client.ts

3. Register in src/index.ts (already automatic via registerXxxTools)
