Building a Browser Harness MCP for AI Agents
Erstellen eines Browser-Harness/MCP für KI-Agenten
Ein Browser-Harness, erstellt mit Playwright, MCP und dem GitHub Copilot SDK.
Einrichtung
npm install
npx playwright install chromiumLegen Sie die Umgebungsvariablen für Azure OpenAI fest:
export AZURE_OPENAI_ENDPOINT="https://..."
export AZURE_OPENAI_API_KEY="..."
export AZURE_OPENAI_API_VERSION="2025-04-01-preview"
export AZURE_OPENAI_DEPLOYMENT="gpt-5.4"Standardmäßig startet der Harness Playwright Chromium. Um stattdessen eine Verbindung zu Chrome herzustellen, starten Sie es mit einem dedizierten Profil und exportieren Sie seinen CDP-Endpunkt:
google-chrome \
--remote-debugging-port=9222 \
--user-data-dir="$PWD/.agent-browser" \
--no-first-run
export BROWSER_CDP_URL="http://127.0.0.1:9222"Related MCP server: playwright-browser
Ausführen
npm start -- "Open example.com and print the page title."Führen Sie die Live-Aufgaben aus:
npm run eval
npm run eval -- --task amazonDie Codeausführungslaufzeit ist keine Sicherheitsgrenze. Führen Sie generierten Code in einem isolierten Prozess oder einer VM aus, bevor Sie dieses Muster mit nicht vertrauenswürdigen Eingaben verwenden.
