# Liftoff: fastest setup with one command

> Interactive CLI wizard to sign in, provision API keys, detect your framework, and instrument your app.

Liftoff is the fastest way to set up observability. Run it from the project you want to instrument:

```bash theme={null}
npx @contextcompany/liftoff
```

Requires **Node.js 18+**. Liftoff walks you through setup step by step:

## What Liftoff does

1. **Sign in** — Opens your browser to authenticate with The Context Company. You can skip sign-in and add `TCC_API_KEY` manually later.
2. **Provision API key** — Creates a production ingestion key and writes `TCC_API_KEY` to `.env.local` (Next.js) or `.env` (other projects), unless one already exists.
3. **Detect framework** — Auto-detects your stack when possible, then asks you to confirm. Supports Vercel AI SDK, Mastra, Pi, OpenClaw, Claude Agent SDK, LangChain and LangGraph, CrewAI, Agno, and custom instrumentation (TypeScript and Python). Also detects your package manager.
4. **Instrument** — Fetches a tailored instrumentation prompt for your framework and copies it to your clipboard. Paste it into your AI coding agent (Cursor, Claude Code, etc.) to install the SDK and wire tracing against your codebase. Liftoff does not edit your source files directly.
5. **MCP server** (optional) — Wires `https://api.thecontext.company/mcp` into detected editors (Cursor, Claude Code, Codex, Windsurf). OAuth sign-in happens the first time you use a tool.
6. **Slack** (optional, requires sign-in) — Opens the dashboard to connect your Slack workspace for alerts and recaps.

When setup finishes, Liftoff prints a summary and the command to run your dev server. Check [Runs](https://www.thecontextcompany.com/prod/runs) in the dashboard to confirm traces are flowing.

## Options

```text theme={null}
--api-base <url>  Override the TCC API base URL (default: https://api.thecontext.company)
--help, -h        Show help
--version         Show the installed version
```
