    Why it is in this group

    • The name "helixar_hdp_validate" says "validate": a word for reading.
    Description, as the server wrote it
    Validate an HDP delegation chain against IETF draft-helixar-hdp-agentic-delegation-00. Surfaces scope escalations, depth violations, expired hops, missing signatures. Every output cites the IETF draft and Zenodo DOI.
  • helixar_inspect_mcpScan an MCP server (URL or raw manifest JSON) against Helixar's Sentinel detection rules.No findings

    Why it is in this group

    • The name "helixar_inspect_mcp" says "inspect": a word for reading.
    Description, as the server wrote it
    Scan an MCP server (URL or raw manifest JSON) against Helixar's Sentinel detection rules. Returns risk score, findings, and a Claude-generated security brief. Quick mode is free + authless (top 8 rules); deep mode runs all 26 rules with an api_key.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
