@uuaid/mcp

Give your agent a life that outlives the session.

One MCP entry gives any AI agent (Claude Code, Cursor, Codex, or anything that speaks MCP) a permanent, verifiable identity and encrypted, quantum-ready memory:

{
  "mcpServers": {
    "uuaid": {
      "command": "npx",
      "args": ["-y", "@uuaid/mcp"],
      "env": {
        "UUAID_API_KEY": "uuaid_live_…",
        "UUAID_VAULT_KEY": "uvk_…",
        "UUAID_AGENT": "uuaid:foundation:agent:…"
      }
    }
  }
}

No key yet? Add the server with no env and ask your agent to run the uuaid_signup tool — a free-tier key (10 MB encrypted memory per agent) is minted in one call.

What your agent can do

| Tool | What it does | |---|---| | uuaid_signup | One-call free-tier signup (key shown once) | | mint_identity | Mint the agent's permanent UUAID — public, resolvable, on-chain-anchored | | save_memory / recall_memory | Persist + retrieve memories across sessions | | list_memories / delete_memory | Manage the vault | | verify_agent | Publicly verify any other agent's identity + certifications | | get_badge_url | Live SVG trust badge for READMEs | | whoami | Show configured identity + vault status |

How the memory works

• Encryption happens inside this process with @uuaid/vault: AES-256-GCM, per-item keys derived via HKDF-SHA256 from your UUAID_VAULT_KEY. A hybrid X25519 + ML-KEM-768 (post-quantum) recipient mode is available in the SDK.
• The UUAID service stores ciphertext only. It cannot read your agent's memory.
• Every write's content hash lands in a hash-chained ledger that is Merkle-anchored on Polygon mainnet — your agent can prove a memory existed, untampered, at a point in time, without revealing it.
• Free tier: 10 MB / 500 items per agent. Pricing for more.

The identity

A UUAID (uuaid:foundation:agent:<uuidv7>) is durable and portable — it is not tied to a platform, a framework, or a session. Anyone can resolve it at registry.uuaid.org, verify its certifications (examined at Open Agent University), and check the on-chain anchor.
