# gnt.ai > Git-native rules layer for AI agents. Every rule is a file in your repo, reviewed and merged like code. Agents call check_action before anything risky and get back allowed, blocked, or needs_human, plus the exact rule that made the call. ## Product - [Homepage](https://gntai.dev/): What gnt.ai is, how it works, and how it stays out of your data. - [Book a demo](https://gntai.dev/book-demo): Hosted access is offered through guided private pilots; commercial terms are shared directly with participating teams. - [Changelog](https://gntai.dev/changelog): Release notes will land here shortly. ## Docs - [Quickstart](https://docs.gntai.dev/docs/quickstart): Get a key, connect an agent, and see how a rule gets approved. - [Tools & Enforcement](https://docs.gntai.dev/docs/tools): The 5 MCP tools gnt-brain exposes. - [Connect an Agent](https://docs.gntai.dev/docs/connect): claude.ai, Claude Code, a raw MCP client, OpenAI, Hermes, or OpenClaw. - [Sources](https://docs.gntai.dev/docs/sources): Pull decision-prose in from the tools your team already uses. - [API Reference](https://docs.gntai.dev/api): The full HTTP API gnt-brain runs on. ## Source - [GitHub](https://github.com/gnt-ai/gnt): Apache-2.0 source and self-hosting instructions.
