Quickstart — observe in about a minute.

Engineers shouldn’t need a sales call to try Observe. Install Optics, wrap a process, export proof. Enforcement is Gate; Absolute Control is Phantom Engine.

Install ladder

No account. No conversation retention. Sight Loop only — observe.

  1. 01

    Install the CLI

    One global install on macOS, Linux, or Windows (WSL).

    npm i -g @vantio/cli

  2. 02

    Wrap the agent process

    Prefix your usual command. Optics watches outbound connections — never the conversation.

    vantio run node agent.js

  3. 03

    Optional: Optics MCP

    Read-only observe in Cursor (or similar). List runs, export proofs, discover hosts. Cannot block or enforce.

    npx -y @vantio/optics-mcp

    Cursor · mcp.json

    {
  "mcpServers": {
    "vantio-optics": {
      "command": "npx",
      "args": ["-y", "@vantio/optics-mcp"]
    }
  }
}

  4. 04

    Prove & discover

    Export a shareable proof or browse local run history — no account required.

    vantio prove
vantio discover --local
