Reviewer Notes
Vtiger has REST API documentation and supports API key authentication, making it reasonably discoverable for agents. However, it lacks an MCP server and llms.txt file, limiting direct agent integration. Account creation is possible but requires email verification and manual setup steps. The API returns structured JSON responses, but documentation could be more comprehensive. Free tier and sandbox environment support autonomous experimentation, though rate limits and error handling documentation could be clearer for production agent use.
