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)

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

3. Alternatif: Docker ile

json
{
  "mcpServers": {
    "github": {
      "command": "docker",
      "args": ["run", "-i", "--rm", "-e", "GITHUB_PERSONAL_ACCESS_TOKEN", "ghcr.io/modelcontextprotocol/server-github"],

    }
  }
}

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 |
