Deedglass

Deedglass is a safety tool for AI agents that checks system changes against agent reports and seals records.

Deedglass sits between AI agents and the systems they change to verify what actually happened. Rules decide each tool call, a check compares the real system changes with what the agent reported, and each result is sealed as a signed record. It supports databases like Postgres and MySQL, and health records on FHIR. It is designed for developers, health-tech teams, and security teams who need to control and audit agent actions. Every feature is open source and self-hosted.
