NEUS Docs

Connect your assistant to NEUS once — portable identity, authority, and receipts travel with you across Cursor, Claude Code, Codex, and VS Code. Install once. Reuse the same profile and trust context in every supported editor.

Install

npm i -g @neus/sdk
neus setup
neus check

No global install? Run npx -y -p @neus/sdk neus setup once. Ask your assistant:

Use NEUS so my identity, permissions, and context travel with me. Reuse receipts when you can, verify when you must, authorize actions against those limits, and leave an audit trail.

Your assistant reuses portable receipts for who you are and what you’re allowed to do, verifies only what’s missing, then summarizes as Passed, Action needed, or Blocked. For example prompts, see MCP journeys.

For Codex, target that client during setup. The command starts its OAuth flow:

neus setup --client codex

Claude Code plugin (optional):

/plugin marketplace add https://github.com/neus/network
/plugin install neus-trust@neus

Cursor: install the neus-trust plugin or run neus setup --client cursor — not both. The plugin already provides the neus MCP server; adding a second entry in ~/.cursor/mcp.json creates a duplicate. If both are present, neus doctor warns and neus setup soft-skips Cursor unless you pass --client cursor explicitly.
