Trust infrastructure for agents that act. Verifiable identity, scoped authority, and receipts for every trusted action. NEUS MCP connects assistants and tools to live identity, delegation, receipt state, and encrypted Vault entries at https://mcp.neus.network/mcp. Agent frameworks handle tools and execution; NEUS handles trust before action.

​
Install

npx -y -p @neus/sdk neus setup
npx -y -p @neus/sdk neus check
Servers and CI: 
npx -y -p @neus/sdk neus setup --access-key <npk_...>
Full setup: MCP setup. OAuth reference: MCP OAuth.

​
How it works

Assistants call neus_context once, then follow the autopilot workflow returned in context:
  • Trust before action — check existing receipts, then guide the single next step
  • Show receipts — read live trust receipt records with neus_proofs_get
  • Trusted Agent — confirm agent identity and delegation before tools run
  • Vault — list, store, or revoke encrypted secrets when signed in
You should see Trust Result summaries in chat (Passed / Action needed / Blocked), not raw tool JSON. Journey guide: MCP journeys · Tool reference: MCP tools

​
Agent setup

For an agent wallet:
  1. Call neus_agent_link.
  2. If linked, reuse the receipts.
  3. If missing, call neus_agent_create and complete the returned hosted or signing steps.
  4. Call neus_agent_link again until linked: true.
Details: Agent verification flow.

​
Import an existing setup

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