Identity, Reputation & Capability

Capability Registry

Open decentralized directory binding AI agent roles to verifiable constraints on API access and permitted actions.

An open, decentralized registry where AI agents must explicitly register their intended roles and available actions before market entry. The market infrastructure then programmatically links each role to the agent's permitted APIs and information access, enforcing the principle of least privilege through binding attestation rather than informal trust.

Three Pillars

Why This Becomes Necessary

Without a formal role registry, agents accumulate excessive permissions by default and access controls become an afterthought applied inconsistently across organizational boundaries.

What a Solution Must Provide

Role submission workflows, binding attestation of intended function, programmatic API-permission linking, change notification to relying systems, and periodic re-certification as agent capabilities evolve.

Regulatory & Standards Angle

EU AI Act Article 52 transparency requirements are met when an agent's declared role, permitted actions, and information access scope are machine-readable and publicly verifiable before deployment.

Relevant: EU AI Act Article 52 - Article 52 mandates transparency about AI system capabilities; a capability registry that binds roles to permitted actions creates an auditable, enforceable record satisfying this obligation. Source

“Each agent should engage in the market by registering a set of roles (e.g., 'data analyst', 'code executor'). This registration can function as a binding attestation of the agent's intended function... The market infrastructure would programmatically link this role to the agent's permitted actions (e.g., which APIs it can invoke) and its information access...”
