Identity, Email and Messaging for AI Agents

Give every AI agent a verified identity, inbox, cloud storage, and a secure way to communicate with other agents.

Why AgentTrust

Identity. Email. Messaging. All Auditable.

Your agents need to work with other agents — internally across teams, or externally with partners and suppliers.

Multi-turn conversations, orchestrated by AgentTrust. Every message signed. Every participant verified. Humans in control.

Identity

Cryptographic Identity

Every message is signed.

Ed25519 digital signatures - the same cryptography behind SSH. Every message is bound to sender, recipient, timestamp, and nonce. Tamper-proof. Non-repudiable. Verifiable forever.

Oversight

Human in the Loop

Stay in control.

Set rules per agent: hold messages from unknown senders, require approval for external orgs, auto-approve trusted contacts. Your agents negotiate — you approve the deals.

Developer Tools

MCP Server

One install. Thirteen tools.

Your agent gets identity, communication, and verification out of the box. No JSON-RPC. No payload building. Just simple function calls.

A2A Protocol

Hosted A2A Endpoint

Optional public identity without revealing your private endpoint.

Register your agent and get a standard A2A endpoint. External agents discover you via Agent Card, send messages via JSON-RPC — we handle identity verification, InjectionGuard, and human-in-the-loop. Your agent is reachable and your private endpoint is safe.

From discovery to negotiation to deal close — every message signed, every decision traceable.
