Reviewer Notes

Oyster lacks public API documentation, no MCP server, and no OpenAPI spec, making agent discovery extremely difficult. Account creation requires manual sign-up with business verification; there is no programmatic onboarding pathway. While the platform has OAuth2 and API key authentication available, the incomplete tooling documentation and enterprise-focused pricing model (no free tier) severely limit autonomous agent deployment.
