{
  "mcpServers": {
    "mcp-chrome": {
      "command": "npx",
      "args": [

Ouvrez Claude Desktop → Settings → Developer → Edit Config. Redémarrez après avoir enregistré.

~/.cursor/mcp.json · .cursor/mcp.json

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

    }
  }
}

Cursor utilise le même schéma mcpServers que Claude Desktop. La config projet l'emporte sur la globale.

VS Code → Cline → MCP Servers → Edit

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

Cliquez sur l'icône MCP Servers dans la barre latérale Cline, puis "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

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

Même format que Claude Desktop. Redémarrez Windsurf pour appliquer.

~/.continue/config.json

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

Continue utilise un tableau d'objets serveur plutôt qu'une map.

~/.config/zed/settings.json

{
  "context_servers": {
    "mcp-chrome": {
      "command": {
        "path": "npx",

          "-y",
          "mcp-chrome-bridge"
        ]
      }
    }
  }
}

Ajoutez dans context_servers. Zed recharge à chaud à la sauvegarde.

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

Une seule ligne. Vérifiez avec claude mcp list. Supprimez avec claude mcp remove.

Cas d'usage

Usages concrets : Chrome MCP

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

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

Quand l'utiliser : You're logged into a paywalled site or gated dashboard and want Claude to read it.

Prérequis

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

Déroulement

Confirm tabs

List my open Chrome tabs.✓ Copié

→ Tab titles + URLs for every active tab
Extract

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

→ 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?✓ Copié

→ Synthesis with per-tab citations

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

Pièges

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

Combiner avec : memory

Catch UI regressions by screenshotting flows in your dev build

👤 Frontend engineers ⏱ ~30 min intermediate

Quand l'utiliser : You just shipped a CSS refactor and want a visual diff on 10 core pages.

Déroulement

Open baseline

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

→ Screenshots captured with filenames matching URLs
Compare

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

→ Per-page diff report with concrete observations

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

Pièges

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

Combiner avec : filesystem

Combinaisons

Associez-le à d'autres MCPs pour un effet X10

mcp-chrome + filesystem

Save extracted pages to disk for later indexing

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

mcp-chrome + memory

Remember key findings across browsing sessions

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

Outils

Ce que ce MCP expose

Outil	Entrées	Quand appeler	Coût
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

Coût et limites

Coût d'exécution

Quota d'API: Local — unlimited
Tokens par appel: DOM extracts can be large; 5k–50k tokens
Monétaire: Free
Astuce: Use read_tab with selector to scope extraction instead of pulling the full DOM

Sécurité

Permissions, secrets, portée

Portées minimales : chrome.tabs chrome.scripting

Stockage des identifiants : None — Chrome holds the sessions

Sortie de données : Tab contents flow through the MCP client to your LLM provider

Ne jamais accorder : access to incognito without reason

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

Dépannage

Erreurs courantes et correctifs

Extension not detected

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

Vérifier : 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.

Alternatives

Chrome MCP vs autres

Alternative	Quand l'utiliser	Compromis
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
