--- title: "Adding MCP Servers from GitHub" --- This guide provides a step-by-step walkthrough of how to use Cline to build an existing MCP server from a GitHub repository. ## **Finding an MCP Server** There are multiple places online to find MCP servers: - **Cline can automatically add MCP servers to its list, which you can then edit.** Cline can clone repositories directly from GitHub and build the servers for you. - **GitHub:** Two of the most common places to find MCP servers on GitHub include: - [Official MCP servers repository](https://github.com/modelcontextprotocol/servers) - [Awesome-MCP servers repository](https://github.com/punkpeye/awesome-mcp-servers) - **Online directories:** Several websites list MCP servers including: - [mcpservers.org](https://mcpservers.org/) - [mcp.so](https://mcp.so/) - [glama.ai/mcp/servers](https://glama.ai/mcp/servers) These directories allow users to sort the servers by various criteria such as downloads, date, stars, and use case. Each entry provides information such as features, tools, and configuration instructions. - **PulseMCP:** This website has a blog post discussing how AI could use MCP servers to make websites obsolete. PulseMCP also includes an FAQ section about MCP servers: [https://www.pulsemcp.com/](https://www.pulsemcp.com/) ## **Building with Cline** 1. **Initiate the Process:** Provide Cline with the following information: - **GitHub Repository URL:** The URL of the server's repository. - **README.md Contents:** This is optional but helpful for Cline to understand the server's purpose and configuration. You can copy the README.md file from the GitHub repository. 2. **Example Interaction with Cline:** ``` User: "Cline, I want to add the MCP server for Brave browser control. Here's the GitHub link: @https://github.com/modelcontextprotocol/servers/tree/main/src/brave-search Can you add it?" Cline: "OK. Cloning the repository to the MCP directory. It needs to be built because it has a 'package.json' file. Should I run 'npm run build'?" User: "Yes, build it." Cline: "Build complete. This server needs a browser path. Where's your Brave browser executable?" User: "It's in '/Applications/Brave Browser.app/Contents/MacOS/Brave Browser'." Cline: "OK. I've updated the server config with that path and added it to 'cline_mcp_settings.json'. Anything else?" User: "No, that's all. Let's test it." Cline: "Great! Starting the MCP Inspector to test the server connection. After that, we can try controlling the browser from Cline." ``` 3. **Cline's Actions:** Based on your instructions, Cline will perform the following: - **Repository Cloning:** Cline will clone the repository to your local machine, usually in the directory specified in your configuration. - **Tweaking:** You can guide Cline to modify the server's configuration. For instance: - **User:** "This server requires an API key. Can you find where it should be added?" - Cline may automatically update the `cline_mcp_settings.json` file or other relevant files based on your instructions. - **Building the Server:** Cline will run the appropriate build command for the server, which is commonly `npm run build`. - **Adding Server to Settings:** Cline will add the server's configuration to the `cline_mcp_settings.json` file. ## **Testing and Troubleshooting** 1. **Test the Server:** Once Cline finishes the build process, test the server to make sure it works as expected. Cline can assist you if you encounter any problems. 2. **MCP Inspector:** You can use the MCP Inspector to test the server's connection and functionality. ## **Best Practices** - **Understand the Basics:** While Cline simplifies the process, it's beneficial to have a basic understanding of the server's code, the MCP protocol ([learn more](/mcp/mcp-overview)), and how to configure the server. This allows for more effective troubleshooting and customization. - **Clear Instructions:** Provide clear and specific instructions to Cline throughout the process. - **Testing:** Thoroughly test the server after installation and configuration to ensure it functions correctly. - **Version Control:** Use a version control system (like Git) to track changes to the server's code. - **Stay Updated:** Keep your MCP servers updated to benefit from the latest features and security patches.
