# MCP Server for GitHub: Connect the Official Server in Two Minutes (and When to Build Your Own)

> The fastest way to give Claude, Copilot, or Cursor real access to your repos, issues, and PRs is the official github/github-mcp-server — a hosted endpoint you point your agent at. Here's the exact config for each client, how to scope it so an agent can't do more than you meant, and when you'd build your own MCP server instead.

## Key takeaways

- An MCP server is a program that exposes tools, data, and prompts to an AI agent over the Model Context Protocol — the open standard that lets any compatible client (Claude, Copilot, Cursor) call the same tools without custom glue.
- For GitHub, you almost never build one: GitHub ships the official `github/github-mcp-server`, and the fastest path is its hosted endpoint, `https://api.githubcopilot.com/mcp/`. Point your client at that URL, authenticate with OAuth or a Personal Access Token, and your agent can read repos, open and review PRs, triage issues, read Actions logs, and run code/secret scanning — ~80 tools across 20 toolsets.
- Scope it before you trust it: pass `--read-only` (or the `/readonly` URL suffix) so an agent can look but not write, and restrict `--toolsets` to just what the task needs. Least privilege is the whole game once an agent can push commits.
- Build your own MCP server only when you need to expose YOUR system — an internal API, a database, a private service. The current TypeScript SDK is `@modelcontextprotocol/server` (v2); the Python SDK is `mcp` (v2), whose high-level server class is now `MCPServer` (renamed from `FastMCP`).

## At a glance

| Client | Where the config lives | Config key | Fastest working setup |
| --- | --- | --- | --- |
| VS Code (Copilot) | `.vscode/mcp.json` (or user settings) | `servers` | Remote HTTP + OAuth — no token to paste |
| Claude Code (CLI) | `claude mcp add-json` | — | Remote HTTP + `Authorization: Bearer <PAT>` header |
| Claude Desktop | `claude_desktop_config.json` | `mcpServers` | Local Docker + `GITHUB_PERSONAL_ACCESS_TOKEN` |
| Cursor | `~/.cursor/mcp.json` | `mcpServers` | Remote HTTP + `Authorization: Bearer <PAT>` header |

If you searched **"[mcp server](/topics/mcp) github,"** you almost certainly want one of two things: connect your AI agent to GitHub, or build a server that lives *on* GitHub. This piece answers the first — the one most people mean — and points you at the second at the end.
The short version: **you don't build a GitHub MCP server. GitHub already ships one.** It's called [`github/github-mcp-server`](https://github.com/github/github-mcp-server), it's official, and the fastest way to use it is the hosted endpoint:
```
https://api.githubcopilot.com/mcp/
```
Point Claude, Copilot, or [Cursor](/stack/cursor) at that URL, authenticate, and your agent can read your repos, triage issues, open and review pull requests, read Actions logs, and run code and secret scanning — about **80 tools across 20 toolsets**, no server to run. Below is the exact config for each client, then how to scope it so an agent can't do more than you meant.
What an MCP server actually is (30 seconds)
An **MCP server** is a small program that exposes three kinds of things to an AI app over the **Model Context Protocol** — an open client–server standard:
- **Tools** — callable actions the model can invoke (`create_pull_request`, `list_issues`).
- **Resources** — read-only data addressed by URI (a file, a record) the app can load into context.
- **Prompts** — reusable, parameterized templates, often surfaced as slash commands.

The point of the standard is write-once: any MCP-compatible client can talk to the same server, so GitHub writes *one* server and Claude, Copilot, and Cursor all use it. (If you want the deeper cut on the three primitives, we wrote [MCP Tools vs Resources vs Prompts](/posts/2026-06-23-mcp-tools-vs-resources-vs-prompts.html).)
The fastest path: connect the official server
Two ways to run it. Prefer the **remote** server unless you have a reason not to — there's nothing to install and OAuth means no token on disk.
- **Remote / hosted:** `https://api.githubcopilot.com/mcp/`, maintained by GitHub, supports OAuth and PAT.
- **Local:** Docker image `ghcr.io/github/github-mcp-server` (or a Go binary), authenticated with a `GITHUB_PERSONAL_ACCESS_TOKEN`.

VS Code (Copilot)
Create `.vscode/mcp.json`. Note the key is `servers`, not `mcpServers`:
```
{
  "servers": {
    "github": {
      "type": "http",
      "url": "https://api.githubcopilot.com/mcp/"
    }
  }
}
```
On first use, VS Code (1.101+) runs a browser OAuth login — no token to paste. If you'd rather use a token, add a header and an input prompt instead:
```
{
  "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 }
  ]
}
```
Claude Code (CLI)
One command adds the remote server with a token header:
```
claude mcp add-json github '{"type":"http","url":"https://api.githubcopilot.com/mcp","headers":{"Authorization":"Bearer YOUR_GITHUB_PAT"}}'
```
Prefer to keep the token off the network and run locally? Point Claude Code at the Docker image over stdio:
```
claude mcp add github -e GITHUB_PERSONAL_ACCESS_TOKEN=YOUR_GITHUB_PAT \
  -- docker run -i --rm -e GITHUB_PERSONAL_ACCESS_TOKEN ghcr.io/github/github-mcp-server
```
Claude Desktop
Edit `claude_desktop_config.json` (macOS: `~/Library/Application Support/Claude/`; Windows: `%APPDATA%\Claude\`; Linux: `~/.config/Claude/`). Desktop uses `mcpServers`:
```
{
  "mcpServers": {
    "github": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "GITHUB_PERSONAL_ACCESS_TOKEN", "ghcr.io/github/github-mcp-server"],
      "env": { "GITHUB_PERSONAL_ACCESS_TOKEN": "YOUR_GITHUB_PAT" }
    }
  }
}
```
Cursor
Edit `~/.cursor/mcp.json` (Cursor 0.48+ for Streamable HTTP):
```
{
  "mcpServers": {
    "github": {
      "url": "https://api.githubcopilot.com/mcp/",
      "headers": { "Authorization": "Bearer YOUR_GITHUB_PAT" }
    }
  }
}
```
Authentication: OAuth or a token
- **OAuth** (recommended for the remote server): a compatible client runs the login flow for you; the token is held in memory, and there's no app to register up front.
- **Personal Access Token (PAT):** set `GITHUB_PERSONAL_ACCESS_TOKEN` locally, or send an `Authorization: Bearer <PAT>` header remotely. Create one at `github.com/settings/tokens`. A sensible minimum: `repo` for repository operations, `read:packages` to pull the Docker image, `read:org` for org/team access — then use a **fine-grained token scoped to only the repos this task touches**, and rotate it.

For the full auth picture — OAuth 2.1, resource indicators, and the confused-deputy trap that catches most first attempts — see [MCP Authorization Explained](/posts/2026-06-22-mcp-authorization-oauth.html).
Scope it before you trust it
The moment an agent has write tools on your repo, "what could it do?" is a security question, not a hypothetical. Two levers keep it honest.
**Read-only.** Let the agent look but not write:
```
# local flag
./github-mcp-server --read-only
# env var
GITHUB_READ_ONLY=1 ./github-mcp-server
```
On the remote server, append `/readonly` to the URL (e.g. `https://api.githubcopilot.com/mcp/x/issues/readonly`) or send the `X-MCP-Readonly` header.
**Narrow the toolset.** Don't expose 80 tools to a task that only reads issues:
```
# flag
./github-mcp-server --toolsets repos,issues,pull_requests
# env var
GITHUB_TOOLSETS="repos,issues,pull_requests" ./github-mcp-server
```
On the remote server, target a single toolset with the path `https://api.githubcopilot.com/mcp/x/{toolset}` (e.g. `/x/issues`), or send `X-MCP-Toolsets`. The available toolsets: `context`, `actions`, `code_quality`, `code_security`, `copilot`, `dependabot`, `discussions`, `gists`, `git`, `issues`, `labels`, `notifications`, `orgs`, `projects`, `pull_requests`, `repos`, `secret_protection`, `security_advisories`, `stargazers`, `users`.
> Least privilege is the whole game. A read-only, issues-only connection can't force-push to `main` no matter how a tool description or a poisoned issue tries to talk it into it — see [how to harden your repo against agent-poisoned PRs](/posts/how-to-harden-your-repo-against-ai-agent-poisoned-prs.html).

What you get: ~80 tools across 20 toolsets
Once connected, the agent can (subject to your scoping): browse repos, files, branches, commits, tags, and releases; create and triage issues, including sub-issues; open, review, and auto-merge pull requests; read Actions workflow runs and job logs; run code and secret scanning; search code; read users, orgs, and teams; manage notifications, gists, discussions, and projects. It already tracks the current **2026-07-28** MCP spec, so it works with stateless clients and load-balanced hosts out of the box.
When to build your own instead
Build your own MCP server when the thing you want an agent to reach is **yours** — an internal API, a database, a private service. For GitHub itself, the official server already covers the surface, so a hand-rolled one is wasted effort.
If you do need to wrap your own system, the SDKs are small. A minimal **TypeScript** server (current v2 package, `@modelcontextprotocol/server`) exposing one tool over stdio:
```
import { McpServer } from '@modelcontextprotocol/server';
import { StdioServerTransport } from '@modelcontextprotocol/server/stdio';
import * as z from 'zod/v4';

const server = new McpServer({ name: 'greeting-server', version: '1.0.0' });

server.registerTool(
  'greet',
  {
    description: 'Greet someone by name',
    inputSchema: z.object({ name: z.string() })
  },
  async ({ name }) => ({
    content: [{ type: 'text', text: `Hello, ${name}!` }]
  })
);

async function main() {
  const transport = new StdioServerTransport();
  await server.connect(transport);
}

main();
```
The same server in **Python** (package `mcp`, v2 — note the class is now `MCPServer`, renamed from v1's `FastMCP`):
```
from mcp.server import MCPServer

mcp = MCPServer("Demo")

@mcp.tool()
def add(a: int, b: int) -> int:
    """Add two numbers."""
    return a + b

@mcp.resource("greeting://{name}")
def greeting(name: str) -> str:
    """Greet someone by name."""
    return f"Hello, {name}!"
```
Run it against the MCP Inspector to poke at your tools before wiring a client:
```
uv run mcp dev server.py
```
That's the outline; for the full walkthrough — transports, testing, and deployment — see [How to Build an MCP Server](/posts/how-to-build-an-mcp-server.html), and if you already have a REST API, [turn it into an MCP server without rewriting it](/posts/how-to-turn-your-rest-api-into-an-mcp-server.html). Still deciding whether you even need a server? [MCP vs REST for agents](/posts/mcp-vs-rest-api-for-agents.html) draws the line.
The one-line answer
For **GitHub**, don't build — connect `github/github-mcp-server` at `https://api.githubcopilot.com/mcp/`, log in with OAuth, and scope it read-only with a narrow toolset until you trust the task. Build your own MCP server only for systems GitHub doesn't already cover: yours.

## FAQ

### What is an MCP server?

An MCP server is a small program that exposes capabilities — tools (callable actions), resources (read-only data by URI), and prompts (reusable templates) — to an AI application over the Model Context Protocol, an open client–server standard. Any MCP-compatible client (Claude, GitHub Copilot, Cursor, and others) can connect to the same server and use its tools, so you write the integration once instead of per-app.

### Is there an official GitHub MCP server?

Yes. GitHub maintains `github/github-mcp-server`. You can run it two ways: the hosted/remote server at `https://api.githubcopilot.com/mcp/` (nothing to install, supports OAuth and PAT), or locally via the Docker image `ghcr.io/github/github-mcp-server` (or a Go binary).

### How do I connect the GitHub MCP server to VS Code?

Create `.vscode/mcp.json` with a `servers` entry of `type: "http"` and `url: "https://api.githubcopilot.com/mcp/"`. With the remote server, VS Code (1.101+) runs an OAuth login the first time, so you don't paste a token. For a token instead, add an `Authorization: Bearer ${input:github_mcp_pat}` header and a `promptString` input.

### How do I connect it to Claude Code or Cursor?

Claude Code: `claude mcp add-json github '{"type":"http","url":"https://api.githubcopilot.com/mcp","headers":{"Authorization":"Bearer YOUR_PAT"}}'`. Cursor: add a `github` entry under `mcpServers` in `~/.cursor/mcp.json` with the same URL and Authorization header (needs Cursor 0.48+ for Streamable HTTP).

### What can the GitHub MCP server actually do?

Around 80 tools across 20 toolsets: repos and files, branches, commits, tags and releases; issues (including sub-issues); pull requests (including the review workflow and auto-merge); Actions workflow runs and job logs; code and secret scanning; code search; users, orgs, and teams; notifications; gists; discussions; and projects.

### How do I stop an agent from doing too much?

Two levers. Run read-only with the `--read-only` flag, `GITHUB_READ_ONLY=1`, or the `/readonly` URL suffix. And restrict the surface with `--toolsets` / `GITHUB_TOOLSETS` (e.g. `repos,issues,pull_requests`) or the per-toolset URL `https://api.githubcopilot.com/mcp/x/{toolset}`. Pair that with a fine-grained PAT scoped to only the repos the task touches.

### When should I build my own MCP server instead?

When the thing you want the agent to reach is yours — an internal API, a database, a private service — not GitHub. For GitHub itself, the official server already covers ~80 tools, so building your own is wasted effort. To wrap your own system, use the current SDKs: `@modelcontextprotocol/server` (TypeScript v2) or `mcp` (Python v2).

### What changed in the MCP SDKs in 2026?

The SDKs went through a v2 rewrite alongside the 2026-07-28 spec. In TypeScript the monolithic `@modelcontextprotocol/sdk` (v1) split into packages like `@modelcontextprotocol/server` (v2), and tool inputs use Standard Schema (Zod v4, Valibot, or ArkType). In Python, the package is still `mcp`, but the high-level server class `FastMCP` was renamed to `MCPServer`.
