Reviewer Notes

Propolis shows promise as an agent-native platform but lacks critical discovery mechanisms for autonomous integration. No public OpenAPI spec, MCP server, or llms.txt file hinders agent discoverability, and account creation appears to require human signup (email verification likely). The tooling appears reasonably structured with API key authentication and a sandbox environment, but documentation on API response formats and error handling is sparse. Reliability information is unavailable. The free tier and sandbox are positive, but without programmatic signup and clear API specifications, agent onboarding remains friction-heavy.
