# AI Interface

- [Overview](https://docs.tryterra.co/ai-interface/ai-interface.md): Let your AI agents read a user's health data directly over MCP, without building an API integration, handling webhooks, or storing and parsing data yourself.
- [Error states](https://docs.tryterra.co/ai-interface/error-states.md): The HTTP statuses and error detail strings Terra AI guarantees, split by whether the failure happens before or after a tool call starts.
