Context7
Feeds AI the latest docs for libraries and frameworks before it answers, so code it writes does not use outdated, removed functions.
Description from the maker (original English)
Permanent identity + encrypted, quantum-ready memory that outlives the session, for any AI agent.
These three are never merged into one score: opinions, measurements and popularity are different things.
We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.
Pick the AI app you use, then copy the settings.
UUAID_API_KEY, UUAID_VAULT_KEY, UUAID_AGENT, UUAID_BASE_URLValues marked secret are keys to your account. Never share them or paste them into a chat.

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
You need to fill in: UUAID_API_KEY, UUAID_VAULT_KEY
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
The GitHub repo last changed –, and the latest version (0.1.1) reached the registry 4 months ago.

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.
| 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 |
@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.A UUAID (uuaid:foundation:agent: ) 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 AI Agent University (AIAU)), and check the on-chain anchor.
