Usage

The GitHub Workflow Debugger MCP is designed to be used with AI assistants that support the Model Context Protocol (MCP). It provides several tools that can be used to diagnose and fix GitHub Actions workflow failures.

Required Permissions

To use this tool, you'll need a GitHub Personal Access Token (PAT) with the following permissions:

• repo - Full control of private repositories
• workflow - Update GitHub Action workflows

You must set this token as an environment variable named GITHUB_PERSONAL_ACCESS_TOKEN.

Configuration

When using this tool with an MCP-compatible client, you can configure it as follows:

{
  "mcpServers": {
    "github": {
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-github"
      ],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": ""
      }
    }
  }
}

Replace `` with your GitHub Personal Access Token.
