Reviewer Notes
Keyhole lacks dedicated agent discovery infrastructure—no MCP server, OpenAPI spec, or llms.txt file. While it offers a free tier and REST API, account creation requires human verification steps and OAuth flows that are not agent-friendly. The API documentation exists but is not comprehensively structured for agent integration, and there's no programmatic account provisioning, making autonomous agent onboarding difficult. Reliability appears adequate for a SaaS platform, but the absence of clear rate-limit documentation and sandbox environment reduces confidence for production agent use.
