GitHub MCP Server Setup: Stop Tab‑Switching to GitHub in 2026

You're asking Claude to review a pull request, but it has no idea what's in the repo. You copy-paste code back and forth, losing context with every switch. There's a better way. This guide gets your official GitHub MCP Server running on Claude Desktop, Claude Code, or Cursor in under 10 minutes — and includes a free premium cheat sheet (normally $29) with every token scope and config template you'll need.

What GitHub MCP Server does

GitHub MCP Server is GitHub's official Model Context Protocol integration. It lets Claude interact directly with GitHub API endpoints for repositories, issues, pull requests, branches, and code search — no tab switching needed.

Ask Claude to list repos, inspect PRs, review changed files, search code, summarize issues, or prepare fixes before pushing changes.

Before you start

GitHub account

A GitHub account with access to repos you want Claude to read/write.

Claude client

Claude Desktop is easiest; also works with Claude Code and Cursor.

Personal Access Token

Create a token with only needed scopes – repo, read:org, read:user.

Step 1: Create a GitHub token

Go to GitHub Settings → Developer Settings → Personal Access Tokens. Choose classic (simpler) or fine-grained (tighter control).

Recommended GitHub token scopes

Scope	Why you need it
`repo`	Private repos, PRs, issues.
`read:org`	Organization membership & visibility.
`read:user`	User profile for account-level ops.

Public-only? A more limited token works. For real workflows, repo is the practical baseline.

Step 2: Add GitHub MCP Server to Claude Desktop

Open claude_desktop_config.json and add:

Config file paths

macOS: ~/Library/Application Support/Claude/claude_desktop_config.json

Windows: %APPDATA%\Claude\claude_desktop_config.json

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

Replace YOUR_GITHUB_TOKEN with your token from Step 1.

Step 3: Restart Claude and test it

Save the config, fully quit Claude, reopen. Try:

List my GitHub repositories.
Show open pull requests.
Search this repo for auth middleware.
Summarize issues labeled bug.

GitHub MCP Server for Claude Code and Cursor

The same token and package work with Claude Code (CLI config) and Cursor (MCP settings). Keep scopes minimal and document one approved method for teams.

Common GitHub MCP Server errors and fixes

Invalid JSON

Validate commas/braces in config.

Missing/expired token

Check token in env block.

Insufficient permissions

Add repo scope for private repos/PRs.

Not fully restarted

Quit and reopen Claude completely.

npx fails

Install Node.js LTS.

Security best practices

Least privilege

Start with minimal scopes, expand only if needed.

Separate tokens

Use distinct tokens for work and personal projects.

Rotate regularly

Set expiration dates, replace immediately if exposed.

Why GitHub MCP Server is worth installing

For most developers, GitHub MCP Server is the highest‑value MCP server. Once Claude reads repos, PRs, and issues, it becomes far more than a code assistant.

After GitHub, add Context7 MCP for docs and Desktop Commander for local execution.

Frequently asked questions (2026)

What is the GitHub MCP Server?▾

GitHub MCP Server is GitHub's official Model Context Protocol (MCP) server. It lets Claude connect directly to GitHub API endpoints so you can list repositories, search code, manage issues, open pull requests, and review changes without leaving the chat window.

Do I need a GitHub token?▾

Yes. You need a GitHub Personal Access Token to authenticate the GitHub MCP Server. For most Claude workflows, the recommended scopes are repo, read:org, and read:user. If you only need public repositories, you can use a more limited token.

Does GitHub MCP Server work with Claude Desktop only?▾

No. It works with Claude Desktop, Claude Code, Cursor, VS Code, and other MCP-compatible clients. The exact MCP server setup method changes slightly by client, but the same GitHub token and @github/github-mcp-server package are used.

What is the easiest way to install it?▾

The easiest method is using npx in your claude_desktop_config.json file. That avoids manual builds and keeps the GitHub MCP Server easy to update.

Why is the GitHub MCP Server not showing up in Claude?▾

The most common causes are an invalid claude_desktop_config.json file, a missing GitHub Personal Access Token, incorrect token scopes, or forgetting to fully restart Claude Desktop after saving the MCP server configuration.

Is GitHub MCP Server safe to use?▾

It can be safe if you follow least-privilege access. Use the minimum GitHub token scopes required, avoid production org-wide permissions when unnecessary, and review any write action before allowing Claude to proceed with GitHub API requests.
