Reviewer Notes

Eppo has a documented REST API with API key authentication, making basic agent integration possible, and a free tier for experimentation. However, discovery is hindered by lack of MCP server and llms.txt file; agents would need manual documentation lookup. Account creation requires web UI interaction (no programmatic signup), limiting autonomous agent onboarding. The API is functional for querying experiments and feature flags but lacks comprehensive error handling documentation and structured response schemas that would make it truly agent-native. Reliability appears solid given its enterprise positioning, but rate limits and SLA details are not publicly transparent.
