A local cryptographic audit trail for AI agents. It can sign records, check their integrity, and export them using the PiQrypt MCP server.

Use it to create, verify, and export signed records of AI-agent activity for audits or investigations.

It helps show what an agent did and detect changes to its recorded history. The input names GDPR, HIPAA, and the EU AI Act as relevant compliance contexts, but does not promise compliance by itself.

Security

Grade A, and why

audit-trail scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
