Can AI agents use TheoID for on-chain identity?

Agent identity delegation is one of the primary differentiators between TheoID and legacy DID frameworks. No existing SSI protocol was designed with autonomous AI agents in mind. Autheo's native OS-layer identity makes TheoID the first production-ready DID system built for the agentic web.

Direct Answer

Yes. TheoID is designed to support AI agent identity as a first-class use case. An AI agent can hold its own DID with scoped credentials delegated from a human DID holder, without receiving full identity authority. This enables agents to take on-chain actions, sign transactions, access services, and prove authorization, all within a verifiable, revocable permission boundary defined by the human principal.

Why AI agents need native identity

As AI agents take on autonomous tasks (purchasing, executing contracts, accessing APIs), they need to prove who authorized them and what they are permitted to do. Without a native identity layer, agents either impersonate the user (creating security and accountability risks) or operate without verifiable identity (preventing trust). TheoID's delegation model solves both problems.

How agent delegation works in TheoID

A human DID holder creates a scoped verifiable credential granting specific permissions to an agent DID. The agent presents this credential when taking actions within those bounds. The credential can be time-limited, action-limited, or revoked at any time by the issuing human DID. The agent's DID key material is post-quantum secure (Kyber/Dilithium/Falcon), protecting agent identity for the full credential lifespan.

MCP and multi-agent workflows

Autheo's MCP server (accessible at /mcp on autheo.com) allows AI agents to interact with Autheo's API surface using standardized JSON-RPC 2.0 calls. When combined with TheoID delegation, an agent can authenticate to the MCP server using its verifiable credential, execute permitted actions, and have those actions attributed to both the agent DID and the authorizing human DID. This is the foundation for verifiable agentic commerce on Autheo.
