What is sanctuary-framework?

A security wrapper for MCP-compatible AI agents. It adds encrypted state, approval checks, a portable identity and reputation, and an audit of security and privacy gaps.

Protecting agent data, reviewing its security posture, requiring approvals, managing identity and reputation, and controlling information leaving the system.

It helps control what an agent can do and keeps sensitive data under the owner’s keys. Operating-system enforcement is currently live on macOS, but not on Linux or Windows.

Security

Grade A, and why

sanctuary-framework 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 yesterday.

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.
