Requests go through mcptry because browsers can't call most MCP servers directly. Header values are sent to the server for that request only and are never stored or logged.

audit_agent_surface Read-only

Checks nine named ChatGPT, Claude, Perplexity and Google crawler controls by search, user-retrieval and training purpose, then maps observed evidence into discover, understand, trust, act and pay stages. Returns structured evidence, the first evidence gap and an unsigned checksum share receipt. Free, no authentication. It does not observe a real buyer session or test checkout; the target and response bodies are not stored.

compare_mcp_registry_releases

Zero-input Release Signal for H/M Agent Surface, or an official MCP Registry preview comparison for a supplied server name. Compares explicit versions or the latest two, returns structured drift evidence and an unsigned SHA-256 receipt. Free, read-only and no authentication. It never fetches or executes packages, never returns secret values and is not a security or compatibility verdict.

preview_agent_surface_evidence_pack
