Reviewer Notes

Ergo lacks clear developer documentation, official MCP server, and OpenAPI specification—making discovery challenging for agents. Account creation requires wallet authentication, which is not practical for programmatic agent signup. While blockchain tools have testnet sandboxes available, the API tooling and error handling are not optimized for agent workflows. The platform's decentralized nature and blockchain focus limit traditional agent integration patterns.
