Summary
Define OPE grant mechanisms for A2A (agent-to-agent) communication — where OPE grants serve as capability attestations between automated agents, not human users.
Context
Listed under Future Work Section 24. The current spec assumes human-in-the-loop authentication (OAuth consent screens, etc., see Section 7.5). Agentic clients don't have consent screens.
Responsibilities
- Define an alternative auth flow for API-to-API client authentication (e.g., client credentials, service accounts)
- Specify how OPE grants work as capability attestations in multi-agent workflows
- Address revocation and trust verification for non-human entities
- Define appropriate scope constraints for agentic access
