Vantio Optics — See LLM egress. Blind by design, not a proxy. The Free · Open Core observe plane: intercept outbound LLM calls without code changes, capture metadata (never prompts), and export proof — observe only, no enforce.
Run this in your terminal to verify the server starts. Then let us know if it worked — your result helps other developers.

Compress tool outputs, logs, files, and RAG chunks before they reach the LLM. 60-95% fewer tokens, same answers. Library, proxy, MCP server.
Pi Coding Agent extension (CLI-first) — routes bash/read/grep/find/ls through lean-ctx CLI for strong token savings. Optional MCP bridge can register advanced tools.
One local source for the MCP servers, tools, and memory your AI coding agents share, synced into each tool's native config with a review gate and a receipt for every change. No daemon, no lock-in.
97% token reduction for AI coding sessions — zero deps, 21 languages, MCP server

This repo ships Vantio Optics. The same client runs in every tier; higher tiers unlock Vantio Gate (Pro · enforce) and Vantio Phantom Engine (Enterprise · absolute control) on top of Optics.
Vantio tiers unlock governance:
Vantio Optics (Free · Open Core) → Vantio Gate (Pro) → Vantio Phantom Engine (Enterprise)
npm install -g @vantio/cli
vantio run node agent.js # no key needed — Free Observe works immediately
No-install path:
npx @vantio/cli run node agent.js
Optionally connect to your dashboard (Pro/Enterprise features):
vantio login <your-api-key> # validates + saves the key; no env vars needed
Grab your API key from vantio.ai/dashboard.
After a run, generate an auditor-ready proof artifact or explore local history:
vantio prove # HTML proof artifact (Free, no key needed)
vantio discover --local # local run history (Free, no key needed)
vantio discover # full workspace history (Pro/Enterprise)
Optics ships one named workflow — Sight Loop:
vantio run / SDKvantio prove, vantio discover --local, or Optics MCPFull walkthrough: docs/sight-loop.md · MCP: docs/optics-mcp.md · Offline prove: ./scripts/sight-loop-prove.sh
