cd github-mcp-server

# Create virtual environment
python -m venv venv
source venv/bin/activate  # Linux/Mac
# or
venv\Scripts\activate  # Windows

# Install dependencies
pip install -r requirements.txt

Configuration

GitHub Token

Create a Personal Access Token at https://github.com/settings/tokens with these scopes:

• repo - Full control of private repositories

• read:org - Read organization membership

• workflow - Update GitHub Action workflows

Set the token as an environment variable:

# Linux/Mac
export GITHUB_TOKEN=ghp_your_token_here

# Windows (PowerShell)
$env:GITHUB_TOKEN = "ghp_your_token_here"

# Windows (CMD)
set GITHUB_TOKEN=ghp_your_token_here

Usage

Running the Server

# Direct execution
python github_mcp_server.py

# With MCP Inspector (development)
uv run mcp dev github_mcp_server.py

# With MCP CLI
uv run mcp run github_mcp_server.py

Claude Desktop Integration

Add to your Claude Desktop config (~/.config/claude/claude_desktop_config.json):

{
  "mcpServers": {
    "github": {
      "command": "python",
      "args": ["/path/to/github_mcp_server.py"],
      "env": {
        "GITHUB_TOKEN": "ghp_your_token_here"
      }
    }
  }
}

Tool Examples

Create Issue

create_issue("owner", "repo", "Bug: Login fails", body="Steps to reproduce...", labels=["bug"])

List Pull Requests

list_pull_requests("owner", "repo", state="open")

Response Formats

All tools support two response formats:

• markdown (default) - Human-readable formatted output

• json - Structured data for programmatic use

get_repository("owner", "repo", format="json")

Error Handling

The server provides actionable error messages:

• Rate Limiting: Indicates when limits reset

• Not Found: Suggests verifying resource exists

• Authentication: Prompts to check token validity

• Validation: Lists specific field errors
