GitHub MCP Server

GitHub MCP vs gh CLI

Ozellik	GitHub MCP	gh CLI
Kurulum	MCP server config	brew install gh
Auth	PAT token (MCP env)	gh auth login (interactive)
Kullanim	Tool call (agent icinden)	Bash komutu
Rate limit	REST API limit (5000/h)	Ayni
Avantaj	Agent workflow icinde seamless	Terminal scripting
Dezavantaj	MCP server calisir olmali	Agent context'ten cikmak lazim

Ne Zaman Hangisi

GitHub MCP kullan:
  - Agent workflow icinde GitHub islemleri gerektiginde
  - Birden fazla API call zincirlenecekse
  - Structured data response lazimsa

gh CLI kullan:
  - Tek seferlik terminal islemleri
  - PR olusturma/merge (interaktif)
  - Git hook'lari icinde
  - Script/otomasyon icinde

MCP Server Kurulumu

1. GitHub PAT Token Olustur

GitHub Settings > Developer Settings > Personal Access Tokens > Fine-grained
Gerekli permission'lar:
  - Repository: Read/Write
  - Issues: Read/Write
  - Pull Requests: Read/Write
  - Actions: Read/Write (workflow tetikleme)
  - Webhooks: Read/Write (webhook yonetimi)
  - Organization: Read (org API)

2. MCP Config (~/.mcp.json)

{
  "mcpServers": {
    "github": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-github"],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": "<PAT_TOKEN>"
      }
    }
  }
}

3. Alternatif: Docker ile

{
  "mcpServers": {
    "github": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "GITHUB_PERSONAL_ACCESS_TOKEN", "ghcr.io/modelcontextprotocol/server-github"],
      "env": {
        "GITHUB_PERSONAL_ACCESS_TOKEN": "<PAT_TOKEN>"
      }
    }
  }
}

Rate Limiting

Limitler

Auth Tipi	Limit	Reset
PAT (authenticated)	5000 req/h	1 saat
Unauthenticated	60 req/h	1 saat
Search API	30 req/min	1 dakika
GraphQL	5000 points/h	1 saat

Rate Limit Kontrol

mcp_github.get_rate_limit()
// Response: { limit, remaining, reset_at }

Best Practices

1. Conditional requests (If-None-Match header) kullan
2. Pagination ile kucuk sayfalarda cek (per_page: 30)
3. Search API'yi 30 req/min altinda tut
4. 403 + "rate limit exceeded" alirsan reset_at kadar bekle
5. Webhook kullan (polling yerine event-driven)
6. GraphQL kullan (birden fazla REST call yerine tek query)

Workflow Ornekleri

Yeni Feature Workflow

1. Issue olustur (task tanimla)
2. Branch olustur (feature/X)
3. Kod yaz, commit et
4. PR olustur (issue'ya referans ver)
5. Review iste
6. Merge et (squash)
7. Release olustur (tag ile)

Bug Fix Workflow

1. Issue olustur (bug raporu)
2. Branch olustur (fix/X)
3. Fix yaz, test ekle
4. PR olustur (Fixes #issue-number)
5. CI gectigini dogrula
6. Merge et
7. Issue otomatik kapanir

CI/CD Tetikleme

1. Push event -> CI workflow calisir
2. PR event -> Test + lint + security scan
3. Release event -> Deploy workflow calisir
4. Workflow dispatch -> Manuel deploy

Anti-Patterns

Anti-Pattern	Dogru Yol
PAT'i koda gomme	.env veya MCP config env
Tum permission'lari ver	Minimum gerekli scope
Polling ile status kontrol	Webhook kullan
Buyuk sayfa boyutu (100+)	per_page: 30, pagination
Rate limit'i yoksay	get_rate_limit ile kontrol
Force push main'e	Branch protection + PR
