> Using Context7 with the Pi coding agent

Context7 integrates with the [Pi coding agent](https://pi.dev) through the official [`@upstash/context7-pi`](https://github.com/upstash/context7/tree/master/packages/pi) extension. Instead of relying on training data, Pi gets current library documentation directly in your coding sessions.

The extension is self-contained — it registers Context7's tools natively in Pi, so there's no separate MCP server to run.

## Installation

Install the extension with Pi's package command:

```bash
pi install npm:@upstash/context7-pi
```

## Authentication

The extension works out of the box at IP-based rate limits — useful for trying it out. For higher quotas and access to private repositories, generate a free key at the [Context7 dashboard](https://context7.com/dashboard) and export it:

```bash
export CONTEXT7_API_KEY=ctx7sk_...
```

Set it in your shell profile so Pi picks it up on launch.

## What it adds

<CardGroup cols={2}>
<Card title="resolve-library-id" icon="magnifying-glass">
Converts a package or product name to a Context7 library ID (e.g. `Next.js` → `/vercel/next.js`). The agent calls this first.
</Card>
<Card title="query-docs" icon="book">
Fetches documentation and code examples for a resolved library ID.
</Card>
<Card title="context7-docs skill" icon="sparkles">
Teaches the agent to reach for these tools whenever you ask about a library, framework, SDK, API, CLI tool, or cloud service.
</Card>
<Card title="/c7-docs command" icon="terminal">
Runs the resolve + query flow in one shot for manual lookups.
</Card>
</CardGroup>

## Using Context7

Once installed, the skill triggers automatically when you ask about libraries — just ask a docs question and the tools are invoked for you:

```
how do I configure caching in Next.js 16?
use the Prisma syntax for relations
what are the Supabase auth methods?
```

For a manual lookup, use the slash command:

```
/c7-docs <library> <question>
```

For example:

```
/c7-docs next.js Cache Components
/c7-docs supabase row level security
```

## Tips

<AccordionGroup>
<Accordion title="Getting Better Results">
- Be specific about what you're trying to do, not just which library
- Mention versions when they matter
- If the first result isn't right, ask for a different part of the docs
