Endpoint

Local process; no hosted endpoint documented

Authentication

No service credential is documented for the default local server. It controls a Chrome instance; if connected to an existing signed-in browser, the agent can access and act on that session.

Requirements

• Node.js latest LTS and npm
• Current stable Chrome
• MCP-compatible client

Setup steps

1. Default setup: configure command npx and args [-y, chrome-devtools-mcp@latest].
2. For Codex, Google documents codex mcp add chrome-devtools -- npx chrome-devtools-mcp@latest. Gemini CLI documentation also provides gemini mcp add chrome-devtools npx chrome-devtools-mcp@latest.
3. The server starts its own Chrome instance by default. Only connect to an existing browser with explicit user awareness: the agent inherits that browser's active session, cookies, and page access.
4. Reload the client and verify with a harmless page inspection or the documented performance check.

The current reference documents 59 exact names across default and optional categories. Category flags, browser configuration, and experimental features control availability; this is not a fixed universally exposed count.

• MCP grants the agent access to browser content and can let it interact with active sessions; avoid connecting to sensitive logged-in profiles.
• Extension and experimental third-party/WebMCP tool categories require flags; the available catalog depends on configuration.
• Requires local Chrome and Node.js.
• The browser may visit untrusted web content; treat page contents as untrusted data.

• official tool reference

  Google publisher documentation and maintainer repository describe the exact tool names and optional categories. Availability varies by enabled features and browser state.
