The use-case in this template is to simply view and comment on issues within a specific repository but can be extended to meet the needs of your team.\n\nThis MCP example is based off an official MCP reference implementation which can be found here https://github.com/modelcontextprotocol/servers/tree/main/src/github\n\n### How it works\n* A MCP server trigger is used and connected to 3 custom workflow tools. We're using custom workflow tools as there is quite a few nodes required for each task.\n* Behind these tools are regular Github nodes although preconfigured with credentials and targeted repository.\n* The \"Get Issue Comments\" and \"Create Issue Comment\" tools depend on obtaining an Issue Number first. The agent should call the \"Get Latest Issues\" tool for this.\n\n### How to use\n* This Github MCP server allows any compatible MCP client to view and comment on Github Issues. You will need to have a Github account and repository access available before you can use this server.\n* Connect your MCP client by following the n8n guidelines here - https://docs.n8n.io/integrations/builtin/core-nodes/n8n-nodes-langchain.mcptrigger/#integrating-with-claude-desktop\n* Try the following queries in your MCP client:\n * \"Can you get me the latest issues about MCP?\"\n * \"What is the current progress on Issue 12345?\"\n * \"Please can you add a comment to Issue 12345 that they should try installing the latest version and see if that works?\"\n\n### Requirements\n* Github for account and repository access. The repository need not be your own but you'll still need to ensure you have the correct permissions.\n* MCP Client or Agent for usage such as Claude Desktop - https://claude.ai/download\n\n### Customising this workflow\n* Extend this template to interactive with pull requests or workflows within your own company's Github repositories. Alternatively, pull in metrics and generate reports for programme managers.\n* Remember to set the MCP server to require credentials before going to production and sharing this MCP server with others!"
