What is the Attestix MCP server?

Most developer tooling work still happens through a UI a human drives. Attestix MCP server moves it into the conversation instead. AI agent identity, W3C credentials, EU AI Act compliance. 47 MCP tools.

The short version

Make your AI agents EU AI Act compliant with cryptographically verifiable proof.

Getting it running

Installation goes through your MCP client rather than a global install: point it at attestix on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

The tools it exposes

The server publishes 14 tools. What each one is for:

  • create_agent_identity — Create a UAIT from any identity source
  • resolve_identity — Auto-detect token type and register
  • verify_identity — Check existence, revocation, expiry, signature
  • translate_identity — Convert to A2A, DID Document, OAuth, or summary
  • list_identities — List UAITs with protocol/revocation filters
  • get_identity — Get full UAIT details
  • revoke_identity — Mark a UAIT as revoked
  • purge_agent_data — GDPR Article 17 right to erasure across all stores
  • parse_agent_card — Parse an A2A Agent Card JSON
  • generate_agent_card — Generate agent.json for hosting
  • discover_agent — Fetch /.well-known/agent.json from a URL
  • create_did_key — Generate ephemeral did:key with Ed25519 keypair

Things to watch

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • With 14 tools registered it takes up a noticeable share of the context window; turn it off in projects that never touch Attestix.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

How it compares

Among the developer tooling options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Attestix's toolset — create_agent_identity, resolve_identity, verify_identity and 11 more — is a fair guide to whether it matches your workflow. It is maintained by VibeTensor; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against Attestix's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Frequently asked questions

It connects Attestix to MCP-compatible AI assistants such as Claude and Cursor, exposing 14 tools (create_agent_identity, resolve_identity, verify_identity, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with Attestix directly.
