NEUS MCP connects AI tools to identity, scoped authority, trust receipts, and Vault. Install once, then reuse receipts across sessions. Hosted endpoint: https://mcp.neus.network/mcp

​
One-command setup

Install everything detected on the machine in one step: 
npx -y -p @neus/sdk neus setup
npx -y -p @neus/sdk neus check
neus setup configures hosted MCP for detected editors and signs you in automatically. It uses NEUS_ACCESS_KEY from the environment when set; otherwise it starts OAuth for the selected host. Cursor, VS Code, and Claude Code use browser sign-in on neus.network. Codex uses codex mcp login neus. Pass --access-key <npk_...> to override. Use --json for scripts. 
npx -y -p @neus/sdk neus check
Create keys under Account → Access keys on neus.network for servers and CI. Treat access keys like passwords.

​
Disconnect

npx -y -p @neus/sdk neus disconnect --access-key <token>

​
Migrate your workspace

Import existing IDE configuration into a portable NEUS manifest, then export it for another workspace. 
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
--from auto detects Claude Code, Cursor, and Claude Desktop workspaces. Named sources: 
npx -y -p @neus/sdk neus import --from cursor
npx -y -p @neus/sdk neus import --from claude-code
npx -y -p @neus/sdk neus import --from claude-desktop

​
Client setup

Per-editor install paths (Cursor, VS Code, Claude Code, and more): Install NEUS. neus setup connects Cursor, Codex, VS Code, Claude Code, and Cline in one command.

First session
