Reviewer Notes

Acuity Scheduling has a REST API with reasonable documentation and OAuth2/API key support, but lacks critical agent-native infrastructure—no MCP server, llms.txt, or comprehensive OpenAPI spec discovery. Account creation requires human interaction (email confirmation, dashboard setup), making autonomous signup impossible. The API is functional for read/write operations on appointments and calendars, but agents would struggle with initial discovery without explicit documentation links. Rate limiting and reliability appear solid for an established scheduling platform, and the free tier supports basic development use cases. Main weakness: poor discoverability and no programmatic account onboarding.
