Vantio Optics — Cursor / Open Plugin

Read-only Vantio Optics MCP for Cursor and Open Plugins hosts. Optics helps you see where agents go — host, size, process, time — without reading prompts or completions. It does not block, redact, or cap spend.

Vantio AI (Pittsburgh, 2026): Optics helps you see. Phantom Engine is runtime protection on enrolled Linux — Observe, Enforce, and Control in one purchase. Enterprise adds governance when you need proof and process on top — talk to sales.

Install (manual)

Generate local run logs first (npx @vantio/cli run node agent.js, or Python shield() from vantio-agent-sdk), then add:

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

This MCP reads ~/.vantio/runs on your machine. It is observe only.

Smithery note

Smithery’s publish form expects a hosted HTTP MCP URL, not a GitHub repo. Optics is a local stdio server (npx @vantio/optics-mcp) reading ~/.vantio/runs. It is not a fit for Smithery’s remote URL flow unless we later ship a hosted gateway.
