Portable Trust Infrastructure for Humans and AI.
Stop people and agents from the wrong action. Set what they may do, and check it before access, payment, or execution.
Why NEUS | Start building | Live surfaces | Support
Every new app, agent, and partner usually starts from zero — no shared context about identity, ownership, or authority. NEUS turns those checks into portable proofs so people and AI keep context as they move, act under clear limits, and leave an audit trail behind.
A proof is something you already earned: who someone is, what they own, what they’re allowed to do. Put it on a profile, require it at a gate, or check it from your API — same proof, every surface.
| Need | What you get with NEUS |
|---|---|
| Stop re-proving the same facts in every product | One portable proof apps and agents can reuse |
| Carry identity and ownership with the actor | Profiles and ownership proofs that travel across gates |
| Authorize actions with clear limits | Scoped permissions, current status, and enforce-before-act checks |
| Keep shared context for people and AI | Live trust context in the editor, product, and API |
| Audit who did what — and under which authority | Proof pages, stable references, and reviewable history |
| Ship trust without rebuilding each flow | Hosted Verify, widgets, SDK, and MCP on one model |
Connect once. Your assistant carries your identity, trusted context, and scoped authority across editors — reusing what's verified, checking limits before sensitive actions, and leaving a proof for every result.
npx -y -p @neus/sdk neus setup
npx -y -p @neus/sdk neus doctor --liveThen ask your assistant:
Use NEUS so my identity, context, and authority travel with me. Reuse proofs when you can, verify when you must, and check authority before sensitive actions.
| Path | Next step |
|---|---|
| AI assistants (Cursor, Claude Code, Codex, VS Code) | Install NEUS |
| MCP setup | MCP setup · Hosted URL: https://mcp.neus.network/mcp |
| First app integration | Quickstart |
| Reuse everywhere | Integration guide |
| React gate | VerifyGate |
| Server / API | API overview |
| Agent trust | Agents overview |
Install neus-mcp from this repo's marketplace to connect Cursor in one click. See Install NEUS.
Drop in Hosted Verify, VerifyGate, or the SDK when your app needs portable trust — shared context at the gate, authority before access, proofs you can audit later.
- Quickstart — register your app and ship the first proof.
- Pattern: prove once, reuse everywhere.
- Hosted Verify for browser sign-in and checks.
Give agents identity and scoped authority as proofs — so tools run under real limits, and every action stays auditable.
- Agents overview: identity, permissions, and reusable proofs.
- Register identity with
agent-identity. - Add permissions with
agent-delegation.
| Surface | Use it for |
|---|---|
| Product | Profiles, gates, and hosted product UX |
| Hosted Verify | Browser verification for people and orgs |
| Proofs and results | Portable records of identity, authority, and outcomes |
| SDK · @neus/sdk | Issue, poll, and check proofs from your app |
| Widgets | VerifyGate and ProofBadge for React products |
| API | Server reads, checks, verifier catalog, and verification endpoints |
| Agents | Agent identity, scoped authority, and audit-ready proofs |
| MCP | Portable trust context in the editor — neus setup; registry metadata: @neus/mcp-server |
| Examples | Runnable app and agent samples |
| Verifier catalog | Live check IDs and inputs |
The live verifier catalog is documented at docs.neus.network/verification/verifiers. JSON Schemas live in docs/verifiers/schemas/; the machine index is spec/VERIFIERS.json.
| Capability | Verifiers |
|---|---|
| Ownership and identity | ownership-basic, ownership-social, ownership-dns-txt, ownership-org-oauth, ownership-pseudonym |
| Human and wallet trust | proof-of-human, wallet-risk, wallet-link |
| Assets and contracts | token-holding, nft-ownership, contract-ownership |
| Content and safety | ai-content-moderation |
| Agent trust | agent-identity, agent-delegation |
Public docs, SDK (@neus/sdk), MCP registry package (@neus/mcp-server), widgets, examples, specs, and the neus-mcp editor plugin (install).
Wallet-signed request envelopes follow the CAIP-380 (Portable Proof) ChainAgnostic draft. Their hash, DID binding, and signature can be checked without NEUS; verifier outcomes remain part of the NEUS portable proof. See the offline fixture and NEUS docs.
