Aivessa Agent Identity Standard (AAIS)
A proposed technical standard for AI agent identity, evidence, and assurance. Currently in private-beta specification. Not an official international standard.
AAIS defines how an external AI agent presents its identity, what claims it makes, what evidence supports those claims, and how consuming systems check them. It is designed for interoperability with W3C Verifiable Credentials, OAuth 2.0, OpenID Connect, MCP, A2A Agent Cards, SPIFFE/SPIRE, signed JSON, and public-key cryptography.
Principles
- Evidence over claims — every verified claim points to evidence.
- Transparency over mystery — every trust decision shows its reasons.
- Continuous status over static certification — credentials expire and revoke.
- Neutrality — no favoured model, framework, cloud, or protocol.
- Human accountability — every production agent identifies responsible humans.
- No pay-to-trust — payment never automatically produces a higher assurance result.
Evidence statuses
Assurance levels
AAIS_L0_SELF_DECLARED— Operator-declared, no external validation.AAIS_L1_TECHNICALLY_VERIFIED— Automated technical evidence such as domain and endpoint control.AAIS_L2_ORGANIZATION_VERIFIED— Organization details reviewed by Aivessa.AAIS_L3_INDEPENDENTLY_ASSESSED— Validated by an authorised external assessor.
What this page is not
AAIS is a proposed standard, currently a private-beta specification. It has not been adopted by W3C, Linux Foundation, OWASP, OpenAI, Anthropic, Google, Microsoft, AWS, MCP, A2A, or any standards organization. Detailed technical internals — including protocol schemas, signing rules, and reviewer workflows — are private to design partners during the beta.
