• Global Integration: Configure in $HOME/.qwen/settings.json

Context7 MCP with Stdio Mode for Qwen Code CLI

Context7 MCP is a Memory Context Provider that enhances AI models with advanced context management capabilities. This guide shows how to install Context7 MCP in stdio mode and integrate it with Qwen Code CLI.

What is Context7 MCP?

Context7 MCP provides extended context management for AI models, allowing them to maintain and utilize larger amounts of contextual information during interactions. It’s particularly useful for complex coding tasks that require understanding of extensive project context.

Installing Context7 MCP

There are several ways to install Context7 MCP depending on your preference:

Option 1: Using Global Installation

We install the Context7 MCP as global package.

bun i -g @upstash/context7-mcp

Check the installation:

context7-mcp

Add Context7 MCP to Qwen:

qwen mcp add stdio context7-mcp

Option 2: Use Direct with bunx

If you prefer to install it globally but still use the Qwen CLI:

qwen mcp add stdio bunx --bun -y @upstash/context7-mcp

This is to use the Context7 MCP package directly without installing it.

Integrating with Qwen Code CLI

The qwen mcp add command automatically configures Context7 MCP in Qwen’s settings file located at $HOME/.qwen/settings.json. You can verify the configuration by checking the file:

cat $HOME/.qwen/settings.json

You should see an entry similar to:

{
  "mcpServers": {
    "Context7": {
      "command": "bunx",
      "args": ["--bun", "-y", "@upstash/context7-mcp"]
    }
  },
  "selectedAuthType": "qwen-oauth",
  "hasSeenIdeIntegrationNudge": true,
  "ideMode": true
}

This configuration tells Qwen Code CLI to use bunx with the specified arguments when it needs to access the Context7 MCP server.

Verifying the Integration

After configuring the integration, you can verify it works by running Qwen Code CLI:

qwen mcp list

When you use Qwen Code CLI, it will automatically connect to the Context7 MCP server through the stdio interface.

Benefits of Stdio Mode

Running Context7 MCP in stdio mode provides several advantages:

1. Simplicity: No need to manage separate server processes
2. Performance: Direct communication through standard streams
3. Reliability: Fewer network-related issues
4. Resource Efficiency: Lower overhead compared to network-based communication

Usage Example

Once configured, you can use Qwen Code CLI with Context7 MCP integration:

# Navigate to your project directory
cd /path/to/your/project

# Run Qwen Code CLI
qwen-code

# Qwen will automatically utilize Context7 MCP for enhanced context management

You can also verify that the MCP server is properly configured by listing the available MCP servers:

qwen mcp list

This will show all configured MCP servers, including Context7 if it was added successfully.

Troubleshooting

If you encounter issues with the Context7 MCP integration:

1. Ensure the package is properly installed:

   qwen mcp list
   

   This should show @upstash/context7-mcp in the list of installed MCPs.

2. Check that your Qwen Code settings.json has the correct configuration as shown in the configuration section.

3. Restart Qwen Code after making configuration changes.

4. If the MCP isn’t loading, try removing and re-adding it:

   qwen mcp remove @upstash/context7-mcp
   qwen mcp add @upstash/context7-mcp
   

5. Check the Qwen Code logs for any error messages related to MCP loading.

Conclusion

Context7 MCP in stdio mode provides enhanced context management for Qwen Code CLI. By configuring the integration in the global settings.json file, you can leverage extended context capabilities across all your projects without additional setup.

The stdio mode offers a simple and efficient way to run Context7 MCP without the complexity of network-based communication, making it ideal for local development environments.
