## ❌ Without Context7
LLMs rely on outdated or generic information about the libraries you use. You get:
- ❌ Code examples are outdated and based on year-old training data
- ❌ Hallucinated APIs that don't even exist
- ❌ Generic answers for old package versions
## ✅ With Context7
Context7 MCP pulls up-to-date, version-specific documentation and code examples straight from the source — and places them directly into your prompt.
Add `use context7` to your prompt (or [set up a rule](#add-a-rule) to auto-invoke):
```txt
Create a Next.js middleware that checks for a valid JWT in cookies
and redirects unauthenticated users to `/login`. use context7
```
```txt
Configure a Cloudflare Worker script to cache
JSON API responses for five minutes. use context7
```
Context7 fetches up-to-date code examples and documentation right into your LLM's context. No tab-switching, no hallucinated APIs that don't exist, no outdated code generation.
## Installation
> [!NOTE]
> **API Key Recommended**: Get a free API key at [context7.com/dashboard](https://context7.com/dashboard) for higher rate limits.

<summary><b>Install in Cursor</b></summary>
Go to: `Settings` -> `Cursor Settings` -> `MCP` -> `Add new global MCP server`
Pasting the following configuration into your Cursor `~/.cursor/mcp.json` file is the recommended approach. You may also install in a specific project by creating `.cursor/mcp.json` in your project folder. See [Cursor MCP docs](https://docs.cursor.com/context/model-context-protocol) for more info.
> Since Cursor 1.0, you can click the install button below for instant one-click installation.
#### Cursor Remote Server Connection

{
"mcpServers": {
"context7": {
"url": "https://mcp.context7.com/mcp",
"headers": {
"CONTEXT7_API_KEY": "YOUR_API_KEY"
}
}
}
}
```
#### Cursor Local Server Connection

"command": "npx",
"args": ["-y", "@upstash/context7-mcp", "--api-key", "YOUR_API_KEY"]
}
}
}
```
</details>
<details>
<summary><b>Install in Claude Code</b></summary>
Run this command. See [Claude Code MCP docs](https://code.claude.com/docs/en/mcp) for more info.
#### Claude Code Local Server Connection
```sh
claude mcp add --scope user context7 -- npx -y @upstash/context7-mcp --api-key YOUR_API_KEY
```
#### Claude Code Remote Server Connection
```sh
claude mcp add --scope user --header "CONTEXT7_API_KEY: YOUR_API_KEY" --transport http context7 https://mcp.context7.com/mcp
```
> Remove `--scope user` to install for the current project only.
</details>
<details>
<summary><b>Install in Opencode</b></summary>
Add this to your Opencode configuration file. See [Opencode MCP docs](https://opencode.ai/docs/mcp-servers) for more info.
#### Opencode Remote Server Connection
```json
"mcp": {
"context7": {
"type": "remote",
"url": "https://mcp.context7.com/mcp",
"headers": {
"CONTEXT7_API_KEY": "YOUR_API_KEY"
},
"enabled": true
}
}
```
#### Opencode Local Server Connection
```json
{
"mcp": {
"context7": {
"type": "local",
"command": ["npx", "-y", "@upstash/context7-mcp", "--api-key", "YOUR_API_KEY"],
"enabled": true
}
}
}
```
</details>
<details>
<summary><b>Install with add-mcp</b></summary>
Install the MCP server for all your coding agents:
```bash
npx add-mcp https://mcp.context7.com/mcp --header "CONTEXT7_API_KEY: YOUR_API_KEY"
```
Add `-y` to skip the confirmation prompt and install to all detected agents already in use in the project directory.

**[Other IDEs and Clients →](https://context7.com/docs/resources/all-clients)**
<details>
<summary><b>OAuth Authentication</b></summary>
Context7 MCP server supports OAuth 2.0 authentication for MCP clients that implement the [MCP OAuth specification](https://modelcontextprotocol.io/specification/2025-03-26/basic/authorization).
To use OAuth, change the endpoint from `/mcp` to `/mcp/oauth` in your client configuration:
```diff
- "url": "https://mcp.context7.com/mcp"
+ "url": "https://mcp.context7.com/mcp/oauth"
```
OAuth is only available for remote HTTP connections. For local MCP connections using stdio transport, use API key authentication instead.
</details>
## Important Tips
### Add a Rule
To avoid typing `use context7` in every prompt, add a rule to your MCP client to automatically invoke Context7 for code-related questions:
- **Cursor**: `Cursor Settings > Rules`
- **Claude Code**: `CLAUDE.md`
- Or the equivalent in your MCP client
**Example rule:**
```txt
Always use Context7 MCP when I need library/API documentation, code generation, setup or configuration steps without me having to explicitly ask.
```
### Use Library Id
If you already know exactly which library you want to use, add its Context7 ID to your prompt. That way, Context7 MCP server can skip the library-matching step and directly continue with retrieving docs.
```txt
Implement basic authentication with Supabase. use library /supabase/supabase for API and docs.
```
The slash syntax tells the MCP tool exactly which library to load docs for.
### Specify a Version
To get documentation for a specific library version, just mention the version in your prompt:
```txt
How do I set up Next.js 14 middleware? use context7
```
Context7 will automatically match the appropriate version.
## Available Tools
Context7 MCP provides the following tools that LLMs can use:
- `resolve-library-id`: Resolves a general library name into a Context7-compatible library ID.
- `query` (required): The user's question or task (used to rank results by relevance)
- `libraryName` (required): The name of the library to search for
- `query-docs`: Retrieves documentation for a library using a Context7-compatible library ID.
- `libraryId` (required): Exact Context7-compatible library ID (e.g., `/mongodb/docs`, `/vercel/next.js`)
- `query` (required): The question or task to get relevant documentation for
