Trust infrastructure for apps, agents, and ecosystems.
Trust that travels. Add reusable trust receipts before access, payment, or agent action.

What NEUS is

NEUS turns identity, ownership, authority, risk, content, and actions into reusable trust receipts. Your app or agent can check a receipt before allowing access, payment, tool use, delegation, or audit-sensitive work.

Use the hosted url when you want NEUS to own the flow. Use the SDK, widgets, API, or MCP when you want the receipt inside your product, backend, or agent workflow.

Why NEUS

Trust keeps getting rebuilt inside each app, marketplace, workflow, and agent stack. NEUS gives teams one trust layer for the moments that matter:

Need	NEUS gives you
Stop re-building trust from zero	A receipt your product can save, check, and reuse
Bring Your Own Agent (BYOA)	CLI-assisted import for existing local agent setups
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	Proof 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

1. Bring Your Own Agent (BYOA)

If you already have an AI agent configured locally, the NEUS CLI can package supported local agent context from OpenClaw, Cursor, Claude Code, or Claude Desktop:

npx -y -p @neus/sdk neus import

This writes a local portable-agent manifest. Finish identity and delegation through NEUS MCP with neus_agent_create and neus_agent_link.

2. Add trust to an app

Use Hosted Verify, VerifyGate, or the SDK when your app needs a reusable trust receipt.

• Start with Quickstart.
• Follow the integration loop: check -> verify -> save -> reuse.
• Use Hosted Verify when you want NEUS to own the browser step.

2. Add trust to an agent

Use NEUS when an agent needs identity, scoped authority, and receipts for trusted actions.

• Start with Agents.
• Register identity with agent-identity.
• Add scoped authority with agent-delegation.

3. Connect assistants and tools

Wire Cursor, VS Code, Claude Code, and other MCP hosts to the same hosted NEUS endpoint.

npx -y -p @neus/sdk neus setup
npx -y -p @neus/sdk neus auth
npx -y -p @neus/sdk neus doctor --live

Sign in with neus auth (OAuth in your browser). For servers and CI only, use a Profile access key:

npx -y -p @neus/sdk neus setup --access-key <npk_...>

Start each session with tool neus_context.

Bring an existing agent setup:

npx -y -p @neus/sdk neus import --dry-run
npx -y -p @neus/sdk neus import --from openclaw
npx -y -p @neus/sdk neus export --to manifest
