Reviewer Notes

Greenhouse has a documented REST API and OAuth2 support, which aids discoverability, but lacks an MCP server and llms.txt file that would make it more agent-native. Account creation requires manual enterprise sales process with no programmatic signup capability, presenting a significant barrier for agent autonomous operation. The API is reasonably well-structured for recruiting data (candidates, jobs, stages), but pricing is enterprise-focused with no free tier, making experimentation difficult for agents without pre-existing credentials. The sandbox environment helps, but overall agent adoption is limited by the need for human contract negotiation and account setup.
