An authority operating system that governs what autonomous agents can do, on whose behalf, and under what conditions with enforceable boundaries and verifiable
About Guardian
Guardian is an authority operating system that keeps control with humans while autonomous AI systems perform actions. It establishes who has authority over agents, governs how authority is delegated, defines what autonomous systems may do, enforces boundaries at protected execution points, and produces cryptographically verifiable evidence.
Guardian works across the authority lifecycle: establishing authority, defining intentions and constraints, delegating responsibilities, governing execution, verifying effects, preserving evidence, and revoking authority when necessary. It supports individuals, families, businesses, organizations, developers, and regulated systems like banks and healthcare providers.
The platform operates as an open-source SDK, an MCP server, and framework adapters that put each consequential action behind a deterministic decision and a signed receipt. Guardian prevents unauthorized consequences by maintaining human authority between the agent and the consequence.

FAQ
- What happens when an agent tries to perform an action beyond its authority?
- Guardian enforces boundaries at the moment of execution. Actions beyond established limits are either denied or escalated to ask for human approval depending on the authority configuration.
- Can Guardian prevent all unauthorized agent actions?
- Guardian protects actions only when they execute through a Guardian-protected path. An agent that retains credentials, direct tokens, unrestricted shell access, or a logged-in browser session can bypass Guardian's protection.
- Does Guardian detect all prompt injections?
- Guardian does not detect every prompt injection, but it ensures that injected instructions cannot create authority that was not explicitly granted.
- What compliance certifications does Guardian hold?
- Guardian holds no SOC 2, FedRAMP or other third-party certification.
- How do I verify the evidence Guardian produces?
- Every answer from Guardian has a receipt ID. You can check it from the verify link in the answer, or offline with the open-source @odingard/bifrost-verify package.
