- Teams giving AI agents access to third-party APIs
- Worth noticing
- DELETE requests can only be approved one at a time; other writes can use narrow, expiring grants.
Field notes
The request flow supports A2A or MCP and can sit behind a gateway such as LiteLLM. When librarian encounters an unfamiliar API, it says it can inspect an OpenAPI spec or documentation and open a registry pull request for review. Credentials are added through a one-time approval page and stored in a secret store; the homepage says agents and models see only a reference to shared keys.
