OAuth once. Your assistant loads your profile and what it may do in Cursor, Claude Code, Codex, and VS Code. Your backend can read the same saved results through the API. First run: Install NEUS. Access keys: MCP setup. OAuth details: MCP OAuth.

​
How it works

Assistants load your signed-in profile once, then reuse saved results when they can.
  • Look up a saved result before a sensitive action
  • Guide any missing step
  • Confirm agent identity and authority before tools run
  • Store or revoke secrets when signed in
You see Passed, Action needed, or Blocked in chat. Not raw tool output. Journeys: MCP journeys · Tools: MCP tools

​
Agent setup

  1. Call neus_agent_link.
  2. If linked, reuse the results.
  3. If missing, call neus_agent_create and finish the hosted steps.
  4. Call neus_agent_link again until linked: true.
