Attestix – Open-source identity and EU AI Act compliance for AI agents

Summary: Attestix provides cryptographic identities and compliance documentation for AI agents, enabling verifiable proof of identity and regulatory adherence under the EU AI Act. It issues Ed25519 DID identities, W3C Verifiable Credentials, and UCAN delegation chains, creating tamper-proof audit trails without cloud dependency.

What it does

Attestix is an open-source MCP server that assigns cryptographic identities and generates machine-readable compliance evidence for AI agents. It supports 47 tools across 9 modules and runs locally with 284 tests.

Who it's for

It is designed for developers and auditors needing verifiable identity and compliance proof for AI agents interacting under EU AI Act regulations.

Why it matters

It addresses the lack of cryptographic proof for AI agents’ identity and compliance, enabling independent verification and reducing regulatory risk.
