Context7 MCP Troubleshooting Guide

Context7 MCP Installation Guide

This guide provides detailed instructions for installing and configuring the Context7 MCP server on Windows environments. Follow these steps to integrate up-to-date library documentation into your AI coding assistant.

Prerequisites

Step-by-Step Installation

1. Install Context7 MCP globally

Open a terminal (Command Prompt or PowerShell) and run:

npm install -g @upstash/context7-mcp@latest

This will install the Context7 MCP package globally on your system.

2. Verify installation

Confirm that the package was installed successfully:

npm list -g | findstr context7

You should see output similar to:

├── @upstash/context7-mcp@1.0.4 (or latest version)

3. Find installation paths

You will need these paths to configure your MCP settings:

# Get Node.js executable path
where node
# Example output: C:\Program Files\nodejs\node.exe

# Get global npm packages directory
npm root -g
# Example output: C:\Users\username\AppData\Roaming\npm\node_modules

Create a dedicated directory for MCP servers:

mkdir "C:\Users\%USERNAME%\Documents\Cline\MCP\context7-mcp"

5. Configure MCP in Cursor

The configuration file for Cursor is typically located at:

C:\Users\[username]\AppData\Roaming\Cursor\User\globalStorage\saoudrizwan.claude-dev\settings\cline_mcp_settings.json

Edit this file to add Context7 MCP:

{
  "mcpServers": {
    "github.com/upstash/context7-mcp": {
      "command": "C:\\Program Files\\nodejs\\node.exe",
      "args": ["C:\\Users\\[username]\\AppData\\Roaming\\npm\\node_modules\\@upstash\\context7-mcp\\dist\\index.js"],
      "disabled": false,
      "autoApprove": []
    }
    // Other MCP servers may be here
  }
}

Note: Replace [username] with your actual Windows username.

6. Configure MCP in VS Code (Alternative)

If you’re using VS Code, the configuration file can be found at:

C:\Users\[username]\AppData\Roaming\Code\User\settings.json

Add the following configuration:

{
  "mcp.servers": {
    "Context7": {
      "type": "stdio",
      "command": "C:\\Program Files\\nodejs\\node.exe",
      "args": ["C:\\Users\\[username]\\AppData\\Roaming\\npm\\node_modules\\@upstash\\context7-mcp\\dist\\index.js"]
    }
  }
}

7. Restart your application

After making changes to the configuration files, restart Cursor, VS Code, or your MCP-compatible application to apply the changes.

Testing the Installation

Once installed and configured, you can test Context7 MCP by:

  1. Opening your AI assistant (Cursor, VS Code with appropriate extensions, etc.)
  2. Asking a question about a library with the prefix “use context7”

Example:

How do I use React hooks? use context7
