Github MCP Server

github-mcp-server

Skill by ara.so — MCP Skills collection.

The GitHub MCP Server is GitHub's official Model Context Protocol server that connects AI tools directly to GitHub's platform. It enables AI agents to read repositories, manage issues and PRs, analyze code, monitor CI/CD pipelines, and automate workflows through natural language interactions.

What It Does

• Repository Management: Browse code, search files, analyze commits, understand project structure
• Issue & PR Automation: Create, update, and manage issues and pull requests
• CI/CD Intelligence: Monitor GitHub Actions, analyze build failures, manage releases
• Code Analysis: Review security findings, Dependabot alerts, code patterns
• Team Collaboration: Access discussions, manage notifications, analyze team activity

Installation

Remote Server (Recommended)

The remote GitHub MCP Server is hosted by GitHub and requires no local installation.

VS Code (1.101+)

Using OAuth (Recommended):

{
  "servers": {
    "github": {
      "type": "http",
      "url": "https://api.githubcopilot.com/mcp/"
    }
  }
}

Using GitHub PAT:

{
  "servers": {
    "github": {
      "type": "http",
      "url": "https://api.githubcopilot.com/mcp/",
      "headers": {
        "Authorization": "Bearer ${input:github_mcp_pat}"
      }
    }
  },
  "inputs": [
    {
      "type": "promptString",
      "id": "github_mcp_pat",
      "description": "GitHub Personal Access Token",
      "password": true
    }
  ]
}

      "headers": {
        "Authorization": "Bearer YOUR_GITHUB_PAT"
      }
    }
  }
}

Note: Replace YOUR_GITHUB_PAT with ${GITHUB_PAT} if your host supports environment variables.

      "headers": {
        "Authorization": "Bearer ${GITHUB_PAT}"
      }
    }
  }
}

Local Server (Docker)

For hosts without remote MCP support or GitHub Enterprise Server:

{
  "servers": {
    "github": {
      "command": "docker",
      "args": [
        "run",
        "-i",
        "--rm",
        "-e",
        "GITHUB_PERSONAL_ACCESS_TOKEN",
        "ghcr.io/github/github-mcp-server"
      ],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": "${GITHUB_PAT}"
      }
    }
  }
}

Authentication

Creating a GitHub Personal Access Token (PAT)

1. Go to https://github.com/settings/personal-access-tokens/new
2. Select permissions based on your needs:
   • repo - Full repository access (read/write code, issues, PRs)
   • read:org - Read organization data
   • workflow - Update GitHub Actions workflows
   • admin:org - Manage organization (if needed)
3. Generate token and store securely
4. Set as environment variable:

   export GITHUB_PAT=ghp_yourTokenHere
   

Token Security

Store tokens in environment variables, never hardcode:

# .env file
GITHUB_PAT=ghp_yourTokenHere

# Add to .gitignore
echo ".env" >> .gitignore

Troubleshooting

Connection Issues

Problem: Server not connecting

Error: Unable to connect to GitHub MCP server

Solution: Verify server configuration

1. Check URL is correct: https://api.githubcopilot.com/mcp/
2. For local Docker: Ensure Docker is running
3. Restart your IDE/MCP host

Authentication Failures

Problem: 401 Unauthorized

Error: Authentication failed

Solution: Verify token

1. Check PAT is valid: https://github.com/settings/tokens
2. Ensure token has required scopes
3. Verify environment variable is set correctly:

   echo $GITHUB_PAT
   

4. Restart MCP host after updating token

Permission Errors

Problem: 403 Forbidden or 404 Not Found

Error: Resource not accessible

Solution: Check token permissions

1. Verify PAT has required scope (e.g., repo for private repos)
2. Confirm you have access to the repository
3. For organizations, check if SSO is required:
   • Go to https://github.com/settings/tokens
   • Click "Configure SSO" next to your token
   • Authorize the organization

Docker Issues

Problem: Image pull failed

Error: failed to pull ghcr.io/github/github-mcp-server

Solution:

1. Check Docker is running: docker ps
2. Logout if you have expired credentials:

   docker logout ghcr.io
   

3. Pull manually to test:

   docker pull ghcr.io/github/github-mcp-server
   

Rate Limiting

Problem: API rate limit exceeded

Error: API rate limit exceeded

Solution: Authenticated requests have higher limits

1. Ensure PAT is properly configured
2. Wait for rate limit reset (check response headers)
3. For heavy usage, consider GitHub Apps instead of PATs

Enterprise Server Connection

Problem: Cannot connect to GitHub Enterprise Server

Error: Connection timeout

Solution: Check GITHUB_HOST configuration

1. Ensure URL includes https:// scheme:

   "GITHUB_HOST": "https://github.company.com"
   

2. Verify server is accessible from your network
3. Check firewall/VPN settings

Toolset Not Available

Problem: Tool not found

Error: Tool 'create_gist' not available

Solution: Enable required toolset

{
  "headers": {
    "X-GitHub-MCP-Toolsets": "repos,issues,pulls,gists"
  }
}

VS Code Integration Issues

Problem: Server not appearing in VS Code

Server 'github' not found

Solution:

1. Ensure VS Code version is 1.101+
2. Reload VS Code: Cmd/Ctrl + Shift + P → "Developer: Reload Window"
3. Check settings location: .vscode/settings.json or user settings
4. Enable Agent mode in Copilot Chat

Environment Variable Not Resolved

Problem: Token showing as literal string

Authorization: Bearer ${GITHUB_PAT}

Solution: Host-specific syntax

• Some hosts use ${GITHUB_PAT}
• Others use ${input:github_token}
• Some require hardcoded values
• Check host documentation for variable syntax

Testing Connection

Verify server is working:

List repositories in github organization

If successful, you should see a list of repositories. If not, check logs in your MCP host.
