Trust infrastructure for apps, agents, and ecosystems.
Trust that travels. Verify trust before access, payment, or action.
Why NEUS | Start building | Live surfaces
What NEUS is
NEUS makes trust portable across the internet so people, apps, and AI agents can prove what is real before access, payout, or execution.
neus.network is where you manage your profile, trust receipts, agents, and Vault. NEUS Verify is the trust-check result assistants summarize before sensitive actions. NEUS MCP connects assistants. NEUS CLI / SDK installs and embeds trust in your product.
Use Hosted Verify when NEUS should own the browser step. Use the SDK, widgets, API, or MCP when trust should live inside your app, backend, or agent workflow.
Why NEUS
Trust keeps getting rebuilt inside each app, marketplace, workflow, and agent stack. NEUS is trust infrastructure for apps, agents, and ecosystems: reusable receipts instead of starting from zero.
| Need | NEUS gives you |
|---|---|
| Stop rebuilding trust | A receipt your product can save, check, and reuse |
| Assistant setup | One CLI setup for Claude Code, Codex, Cursor, and VS Code |
| Gate access or rewards | Hosted flows, widgets, and server checks for trusted access |
| Trust agents before they act | Agent identity, scoped delegation, and receipts for trusted actions |
| Audit what happened | Receipt pages, receipt reads, tags, and durable references |
| Ship without owning ceremony | Hosted Verify, SDK helpers, API checks, and MCP on the same trust model |
Start building
One command
Detects where you are working and wires hosted NEUS MCP for Claude Code, Codex, Cursor, or VS Code. OAuth sign-in runs automatically when no access key is set.
npx -y -p @neus/sdk neus setup
npx -y -p @neus/sdk neus check
Ask your assistant: "Use NEUS Verify before taking sensitive actions."

Add trust to an app
Use Hosted Verify, VerifyGate, or the SDK when your app needs a reusable trust receipt.
- Quickstart - register your app and run the workflow.
- Follow the workflow: check -> verify -> save -> reuse.
- Use Hosted Verify when you want NEUS to own the browser step.
Add trust to an agent
- Agents - identity, scoped authority, and receipts for agents that act.
- Register identity with
agent-identity. - Add scoped authority with
agent-delegation.
