## ❌ 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LLMs rely on outdated or generic information about the libraries you use.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- ❌ Code examples are outdated and based on year-old training data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 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 in Cursor:

```txt
Create a basic Next.js project with app router. use context7
```

```txt
Create a script to delete the rows where the city is "" given PostgreSQL credentials. use context7
```

Context7 fetches up-to-date code examples and documentation right into your LLM's context.

- 1️⃣ Write your prompt naturally
- 2️⃣ Tell the LLM to `use context7`
- 3️⃣ Get working code answers

No tab-switching, no hallucinated APIs that don't exist, no outdated code generations.

## 🛠️ Getting Started

### Requirements

- Node.js >= v18.0.0
- Cursor, Windsurf, Claude Desktop or another MCP Client

    }
  }
}
```

### Install in Zed

It can be installed via [Zed Extensions](https://zed.dev/extensions?query=Context7) or you can add this to your Zed `settings.json`. See [Zed Context Server docs](https://zed.dev/docs/assistant/context-servers) for more info.

```json
{
  "context_servers": {
    "Context7": {
      "command": {
        "path": "npx",
        "args": ["-y", "@monotool/context7-mcp@latest"]
      },
      "settings": {}
    }
  }
}
```

### Install in Claude Code

Run this command. See [Claude Code MCP docs](https://docs.anthropic.com/en/docs/agents-and-tools/claude-code/tutorials#set-up-model-context-protocol-mcp) for more info.

```sh
claude mcp add context7 -- npx -y @monotool/context7-mcp@latest
```

### Install in Claude Desktop

Add this to your Claude Desktop `claude_desktop_config.json` file. See [Claude Desktop MCP docs](https://modelcontextprotocol.io/quickstart/user) for more info.

```json
{
  "mcpServers": {
    "Context7": {
      "command": "npx",
      "args": ["-y", "@monotool/context7-mcp@latest"]
    }
  }
}
```

### Install in BoltAI

Open the "Settings" page of the app, navigate to "Plugins," and enter the following JSON:

```json
{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "@monotool/context7-mcp@latest"]
    }
  }
}
```

Once saved, enter in the chat `get-library-docs` followed by your Context7 documentation ID (e.g., `get-library-docs /nuxt/ui`). More information is available on [BoltAI's Documentation site](https://docs.boltai.com/docs/plugins/mcp-servers). For BoltAI on iOS, [see this guide](https://docs.boltai.com/docs/boltai-mobile/mcp-servers).

### Using Docker

If you prefer to run the MCP server in a Docker container:

1.  **Build the Docker Image:**

    First, create a `Dockerfile` in the project root (or anywhere you prefer):

    <details>
    <summary>Click to see Dockerfile content</summary>

    ```Dockerfile
    FROM node:18-alpine

    WORKDIR /app

    # Install the latest version globally
    RUN npm install -g @monotool/context7-mcp@latest

    # Expose default port if needed (optional, depends on MCP client interaction)
    # EXPOSE 3000

    # Default command to run the server
    CMD ["context7-mcp"]
    ```

    </details>

    Then, build the image using a tag (e.g., `context7-mcp`). **Make sure Docker Desktop (or the Docker daemon) is running.** Run the following command in the same directory where you saved the `Dockerfile`:

    ```bash
    docker build -t context7-mcp .
    ```

2. **Configure Your MCP Client:**

    Update your MCP client's configuration to use the Docker command.

    *Example for a cline_mcp_settings.json:*

    ```json
    {
      "mcpServers": {
        "Сontext7": {
        "autoApprove": [],
        "disabled": false,
        "timeout": 60,
          "command": "docker",
          "args": ["run", "-i", "--rm", "context7-mcp"],
          "transportType": "stdio"
        }
      }
    }
    ```

    *Note: This is an example configuration. Please refer to the specific examples for your MCP client (like Cursor, VS Code, etc.) earlier in this README to adapt the structure (e.g., `mcpServers` vs `servers`). Also, ensure the image name in `args` matches the tag used during the `docker build` command.*

### Install in Windows
The configuration on Windows is slightly different compared to Linux or macOS (*`Cline` is used in the example*). The same principle applies to other editors; refer to the configuration of `command` and `args`.
```json
{
  "mcpServers": {
    "github.com/monotool/context7-mcp": {
      "command": "cmd",
      "args": [
        "/c",
        "npx",
        "-y",
        "@monotool/context7-mcp@latest"
      ],
      "disabled": false,
      "autoApprove": []
    }
  }
}
```

### Environment Variables

- `DEFAULT_MINIMUM_TOKENS`: Set the minimum token count for documentation retrieval (default: 10000).

Examples:

```json
{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["-y", "@monotool/context7-mcp@latest"],
      "env": {
        "DEFAULT_MINIMUM_TOKENS": "10000"
      }
    }
  }
}
```

### Available Tools

- `resolve-library-id`: Resolves a general library name into a Context7-compatible library ID.
  - `libraryName` (required)
- `get-library-docs`: Fetches documentation for a library using a Context7-compatible library ID.
  - `context7CompatibleLibraryID` (required)
  - `topic` (optional): Focus the docs on a specific topic (e.g., "routing", "hooks")
  - `tokens` (optional, default 10000): Max number of tokens to return. Values less than the configured `DEFAULT_MINIMUM_TOKENS` value or the default value of 10000 are automatically increased to that value.

## Development

Clone the project and install dependencies:

```bash
bun i
```

Build:

```bash
bun run build
```

### Local Configuration Example

```json
{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": ["tsx", "/path/to/folder/context7-mcp/src/index.ts"]
    }
  }
}
```

### Testing with MCP Inspector

```bash
npx -y @modelcontextprotocol/inspector npx @monotool/context7-mcp@latest
```

## Troubleshooting

### ERR_MODULE_NOT_FOUND

If you see this error, try using `bunx` instead of `npx`.

```json
{
  "mcpServers": {
    "context7": {
      "command": "bunx",
      "args": ["-y", "@monotool/context7-mcp@latest"]
    }
  }
}
```

This often resolves module resolution issues, especially in environments where `npx` does not properly install or resolve packages.

### ESM Resolution Issues

If you encounter an error like: `Error: Cannot find module 'uriTemplate.js'` try running with the `--experimental-vm-modules` flag:

```json
{
  "mcpServers": {
    "context7": {
      "command": "npx",
      "args": [
        "-y",
        "--node-options=--experimental-vm-modules",
        "@monotool/context7-mcp@1.0.6"
      ]
    }
  }
}
```

### MCP Client Errors

1. Try removing `@latest` from the package name.

2. Try using `bunx` as an alternative.

3. Try using `deno` as an alternative.

4. Make sure you are using Node v18 or higher to have native fetch support with `npx`.
