Tool changes

No tool definition changes recorded. A server's first observation is its baseline; later probes record what changes.

Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed. How it is computed.

Tools (2)

`helixar_hdp_validate`	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_mcp`	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.

Schemas: list_tools.
