Related MCP server: GitHub MCP Server

Overview

github-mcp-server implements the Model Context Protocol (MCP), enabling standardized communication between LLMs and external systems through:

• Clients: Claude Desktop, IDEs, and other MCP-compatible clients

• Servers: Tools and resources for project management and collaboration

• LLM Agents: AI models that leverage the ability to perform GitHub operations programmatically.

It acts as a bridge between AI models and the GitHub API, offering a set of well-defined tools that follow consistent patterns and handle authentication, validation, error handling, and rate limiting.

Key capabilities:

• GitHub API Integration: Secure and seamless integration with GitHub's REST API

• Comprehensive GitHub Features: Complete management of repos, branches, issues, PRs, and more

• Atomic Feature Architecture: Well-organized modular code structure for maintainability

• Input Validation: Robust validation with Zod schemas for all operations

• Error Handling: Consistent error categorization and reporting

• Rate Limiting: Built-in GitHub API rate limit handling

• Performance Focus: Optimized operations and response formatting

Installation

Prerequisites

• Node.js (v16 or newer)

• A GitHub personal access token with appropriate permissions

Setup

1. Clone the repository:

   git clone https://github.com/cyanheads/github-mcp-server.git
   cd github-mcp-server

2. Install dependencies:

   npm install

3. Create a .env file in the project root with your GitHub token:

   GITHUB_TOKEN=your_github_personal_access_token
   LOG_LEVEL=info
   SERVER_NAME=github-mcp-server

4. Build the project:

   npm run build

5. Start the server:

   node build/index.js

Configuration

The server can be configured through environment variables:

MCP Client Settings

Add to your MCP client settings:

{
 "mcpServers": {
 "github": {
 "command": "node",
 "args": ["/path/to/github-mcp-server/build/index.js"],
 "env": {
 "GITHUB_TOKEN": "your_github_personal_access_token",
 "LOG_LEVEL": "info",
 "SERVER_NAME": "github-mcp-server"
 }
 }
 }
}

Project Structure

This project follows an atomic feature-oriented architecture pattern:

/src
 /configuration // Application configuration
 /dependencyInjection // Tool registry and DI container
 /features // Feature modules organized by domain
 /repositoryManagement
 /resources // Read operations
 /modifications // Write operations
 /branchManagement
 /issueManagement
 /pullRequestManagement
 /fileManagement
 /releaseManagement
 /services // External service integrations
 /githubAccess // GitHub API client and utilities
 /types // Core type definitions
 /utilities // Helper functions and utilities

Each feature domain is split into:

• Resources: Read operations that don't modify data

• Modifications: Write operations that create, update, or delete data

Each operation is contained in its own directory with:

• Operation implementation file

• Type definitions file

• Export index file

Tools

GitHub MCP Server provides a comprehensive suite of tools for interacting with GitHub:

Repository Management Tools

Branch Management Tools

Issue Management Tools

Pull Request Management Tools

File Management Tools

Release Management Tools

Development

Project Structure

The project follows strict naming conventions and directory structure:

• File naming: action.entity.type.ts (e.g., create.repository.operation.ts)

• Each module has a clearly defined purpose

• Types are co-located with their implementation

• All exports are centralized through index files

Scripts

• npm run build - Build the project

• npm run watch - Watch for changes and rebuild

• npm run inspector - Run the MCP inspector tool

• npm run clean - Clean build artifacts

• npm run rebuild - Clean and rebuild the project

• npm run tree - Generate a directory tree representation

Error Handling

The server implements a comprehensive error handling strategy:

• Standardized Error Objects: Consistent error format with categorization

• Input Validation: Pre-validation using Zod schemas

• Rate Limiting Protection: Automatic handling of GitHub API rate limits

• Error Categories:

  • Network errors (connectivity issues)

  • Authentication errors (token problems)

  • Validation errors (invalid input)

  • GitHub API errors (API-specific issues)

  • System errors (unexpected failures)

• Detailed Logging: Structured logging for all operations and errors
