Reviewer Notes

Comena lacks critical agent-discovery infrastructure—no MCP server, OpenAPI spec, or llms.txt file are publicly documented, making it difficult for agents to discover and integrate autonomously. Documentation appears limited with no clear API reference or SDK guidance visible from the public site. Account creation requires manual signup without apparent programmatic options. The platform does offer an API with key-based auth and provides a sandbox environment, which helps with testing, but the absence of structured tooling specs significantly hampers agent native integration. A free tier helps with pricing accessibility, but the overall agent-native experience is below average.
