# What Sentilai does

Your developers are already using AI coding assistants. Sentilai is the control plane
that sits between those assistants and the AI providers behind them, so that every
request is governed and audited without anyone changing how they work.

## The shape of it

There are three parts.

**The Gateway** is a proxy. Claude Code, Cursor, GitHub Copilot, Gemini CLI and Codex CLI
send their requests to it instead of directly to Anthropic or OpenAI. It applies your
policy, records what happened, and forwards the request. Your developers see the same
tools behaving the same way.

**The Endpoint Suite** is a small desktop app on each developer machine. It signs the
developer in with a passkey, registers the machine, and rewrites each AI tool's
configuration so it points at the Gateway. It also governs the MCP servers running
locally on that machine — which the Gateway alone cannot see.

**The Admin Console** is where you set policy, see activity, manage people, and produce
evidence. That is this documentation's main subject.

## What you get that you didn't have

- **An audit trail.** Every AI request, who made it, which tool, which model, what it
  cost, and what the policy decided.
- **Enforcement, not just observation.** Blocking a dangerous MCP tool call, stopping a
  secret before it leaves the building, refusing a request that combines private data
  access with untrusted content and a way out.
- **Evidence.** A point-in-time record of your policy, your access inventory and your
  enforcement, for the auditor who asks.

## What it is not

Sentilai does not read your source code repositories, does not sit in your CI, and does
not replace endpoint security or a code scanner. It governs the traffic between AI
assistants and AI providers, plus the MCP servers those assistants call.

It also does not stop a developer who is determined to bypass it — a personal laptop
with a personal API key is outside any control plane. What it does is make the governed
path the easy path, and make the ungoverned one visible.
