# AI coding agents

> Connect Aethis to Claude Code, Cursor, Windsurf, or another MCP-compatible coding agent.

Aethis exposes 25 tools and 2 prompts via MCP, plus higher-level skills and a CLI. This section is for two readers: the AI coding agent that will call the tools, and the human driving that agent from Claude Code, Cursor, Windsurf, or another MCP-compatible client.

**If you are the human:** connect the MCP server once, restart your editor, then ask your coding agent to use Aethis in plain English. The agent can run decisions, inspect traces, draft tests, create rulesets, and drive the authoring loop for you.

**If you are an agent** or you're telling one to integrate Aethis: read [Onboarding](/agents/onboarding). It's the only page you must read — install command, verification call, auth model, prompt patterns, and the workflow sequences you'll need most.

**If you want to compare interfaces** (MCP vs CLI vs SDK vs REST): see [Which interface to use](/interfaces/which-to-use).

**If you want a worked end-to-end task**: see [Recipes](/recipes/evaluate-a-case) — each one is framed for agent execution with parallel CLI and MCP code paths.

Decision tools (`aethis_decide`, `aethis_schema`, `aethis_explain`, `aethis_next_question`) are public — no API key required. Authoring is in private beta; request access at [aethis.ai/developer-access](https://aethis.ai/developer-access).
