Installieren

Wählen Sie Ihren Client

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "mcp-chrome": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-chrome-bridge"
      ]
    }
  }
}

Öffne Claude Desktop → Settings → Developer → Edit Config. Nach dem Speichern neu starten.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "mcp-chrome": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-chrome-bridge"
      ]
    }
  }
}

Cursor nutzt das gleiche mcpServers-Schema wie Claude Desktop. Projektkonfiguration schlägt die globale.

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "mcp-chrome": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-chrome-bridge"
      ]
    }
  }
}

Klicken Sie auf das MCP-Servers-Symbol in der Cline-Seitenleiste, dann "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "mcp-chrome": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-chrome-bridge"
      ]
    }
  }
}

Gleiche Struktur wie Claude Desktop. Windsurf neu starten zum Übernehmen.

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "mcp-chrome",
      "command": "npx",
      "args": [
        "-y",
        "mcp-chrome-bridge"
      ]
    }
  ]
}

Continue nutzt ein Array von Serverobjekten statt einer Map.

~/.config/zed/settings.json

{
  "context_servers": {
    "mcp-chrome": {
      "command": {
        "path": "npx",
        "args": [
          "-y",
          "mcp-chrome-bridge"
        ]
      }
    }
  }
}

In context_servers hinzufügen. Zed lädt beim Speichern neu.

claude mcp add mcp-chrome -- npx -y mcp-chrome-bridge

Einzeiler. Prüfen mit claude mcp list. Entfernen mit claude mcp remove.

Anwendungsfälle

Praxisnahe Nutzung: Chrome MCP

Do research on sites that require login without handing Claude your password

👤 Researchers, analysts using subscription content ⏱ ~20 min beginner

Wann einsetzen: You're logged into a paywalled site or gated dashboard and want Claude to read it.

Voraussetzungen

Chrome extension installed — Install from Chrome Web Store; the bridge MCP auto-connects
Target site already open and authenticated in Chrome — Log in manually in a regular tab first

Ablauf

Confirm tabs

List my open Chrome tabs.✓ Kopiert

→ Tab titles + URLs for every active tab
Extract

From the Bloomberg tab, extract the article body and the sidebar data table.✓ Kopiert

→ Structured content pulled; no "cannot access" error
Cross-tab synthesis

Across the 3 research-provider tabs I have open, what's the consensus view on X?✓ Kopiert

→ Synthesis with per-tab citations

Ergebnis: Answers backed by real authenticated content, no scraping of login pages.

Fallstricke

Session expires mid-task — Extension surfaces a refresh prompt; reauth in that tab and retry

Kombinieren mit: memory

Catch UI regressions by screenshotting flows in your dev build

👤 Frontend engineers ⏱ ~30 min intermediate

Wann einsetzen: You just shipped a CSS refactor and want a visual diff on 10 core pages.

Ablauf

Open baseline

Open my dev site pages listed in /qa/flows.json and screenshot each into /screenshots/before/.✓ Kopiert

→ Screenshots captured with filenames matching URLs
Compare

After I deploy, take fresh screenshots and diff against /screenshots/before/. Summarize visual changes per page.✓ Kopiert

→ Per-page diff report with concrete observations

Ergebnis: A visual-regression report in 5 minutes, using your real browser environment.

Fallstricke

Screenshots differ due to font loading — Add a sleep or wait_for_selector step before capturing

Kombinieren mit: filesystem

Kombinationen

Mit anderen MCPs für 10-fache Wirkung

mcp-chrome + filesystem

Save extracted pages to disk for later indexing

Extract this tab and write to /research/ai-paper-notes.md.✓ Kopiert

mcp-chrome + memory

Remember key findings across browsing sessions

Summarize what I read today and store it in memory.✓ Kopiert

Werkzeuge

Was dieses MCP bereitstellt

Werkzeug	Eingaben	Wann aufrufen	Kosten
list_tabs	none	Start of any session to see what's available	free
read_tab	tab_id: int	Pull content from a specific tab	free
click	tab_id, selector: str	Interact with page elements	free
screenshot	tab_id, full_page?: bool	Visual capture for diff or review	free
search_tabs	query: str	Find which tab discusses X	free

Kosten & Limits

Was der Betrieb kostet

API-Kontingent: Local — unlimited
Tokens pro Aufruf: DOM extracts can be large; 5k–50k tokens
Kosten in €: Free
Tipp: Use read_tab with selector to scope extraction instead of pulling the full DOM

Sicherheit

Rechte, Secrets, Reichweite

Minimale Scopes: chrome.tabs chrome.scripting

Credential-Speicherung: None — Chrome holds the sessions

Datenabfluss: Tab contents flow through the MCP client to your LLM provider

Niemals gewähren: access to incognito without reason

Extension has broad access by design — only install from the official Chrome Web Store listing

Fehlerbehebung

Häufige Fehler und Lösungen

Extension not detected

Pin the extension; the bridge binary needs the extension polling for it

Prüfen: chrome://extensions shows it enabled

Tab content is blank

Page may use shadow DOM — try read_tab with include_shadow=true

Clicks don't register

Site uses anti-automation (Cloudflare, etc). Try scrolling to trigger lazy-load first.

Alternativen

Chrome MCP vs. andere

Alternative	Wann stattdessen	Kompromiss
chrome-devtools MCP	You want the devtools protocol (console, network, perf) not user automation	DevTools MCP doesn't drive the UI — it inspects it
playwright MCP	You want headless automation in CI	No auth state; bot-detection prone
