Reviewer Notes

Multifactor has an OpenAPI spec and API-key authentication, which supports basic agent integration, but lacks MCP server support and llms.txt discovery. Account creation appears to require human verification (email confirmation and manual dashboard setup), limiting autonomous agent onboarding. The API tooling is functional but documentation could be more comprehensive for agent integration. Main strength: sandbox environment available for testing. Main weakness: no MCP server and challenging programmatic account creation make it harder for agents to self-service.
