Brave DevTools for agents

Full Chrome DevTools MCP parity, rebuilt for Brave.

brave-mcp gives Claude Code, Codex, Cursor, OpenCode, and other MCP clients direct access to Brave for browser automation, network and console debugging, performance analysis, screenshots, accessibility inspection, and memory profiling. A standalone brave-devtools CLI is included too.

Install in one command

Claude Code

claude mcp add brave-devtools --scope user -- npx -y brave-mcp@latest

Cursor

cursor --add-mcp '{"name":"brave-devtools","command":"npx","args":["-y","brave-mcp@latest"]}'

Codex

codex mcp add brave-devtools -- npx -y brave-mcp@latest

OpenCode

opencode mcp add brave-devtools -- npx -y brave-mcp@latest

Restart your client, then try this prompt:

Open my app in Brave. Find console errors and failed network requests, inspect the accessibility tree, run Lighthouse, and explain the highest-impact issue.

Why use this instead of Chrome DevTools MCP?

Use Chrome DevTools MCP when your target browser is Chrome. Use brave-mcp when your target browser is Brave and you want Brave-native discovery, profiles, channels, naming, and privacy defaults without giving up upstream features.

Key features

• Get performance insights: Uses Chrome DevTools to record traces and extract actionable performance insights.

• Advanced browser debugging: Analyze network requests, take screenshots and check browser console messages (with source-mapped stack traces).

• Reliable automation. Uses puppeteer to automate actions in Brave and automatically wait for action results.

Disclaimers

brave-mcp exposes content of the browser instance to the MCP clients allowing them to inspect, debug, and modify any data in the browser or DevTools. Avoid sharing sensitive or personal information that you don't want to share with MCP clients.

brave-mcp officially supports the current Brave release. Beta and Nightly channels can be selected explicitly.

Performance tools may send trace URLs to the Google CrUX API to fetch real-user experience data. This helps provide a holistic performance picture by presenting field data alongside lab data. This data is collected by the Chrome User Experience Report (CrUX). To disable this, run with the --no-performance-crux flag.

Usage statistics

Usage statistics collection is disabled by default in this fork. It can be enabled explicitly with --usage-statistics, which uses the upstream Google Clearcut implementation:

"args": ["-y", "brave-mcp@latest", "--usage-statistics"]

When enabled, Google handles this data in accordance with the Google Privacy Policy. Collection remains disabled if BRAVE_DEVTOOLS_MCP_NO_USAGE_STATISTICS or CI is set.

Update checks

By default, the server periodically checks the npm registry for updates and logs a notification when a newer version is available. You can disable these update checks by setting BRAVE_DEVTOOLS_MCP_NO_UPDATE_CHECKS.

Requirements

• Node.js LTS version.

• Brave current release or newer.

• npm

Getting started

Add the following config to your MCP client:

{
  "mcpServers": {
    "brave-devtools": {
      "command": "npx",
      "args": ["-y", "brave-mcp@latest"]
    }
  }
}

If you are interested in doing only basic browser tasks, use the --slim mode:

{
  "mcpServers": {
    "brave-devtools": {
      "command": "npx",
      "args": ["-y", "brave-mcp@latest", "--slim", "--headless"]
    }
  }
}

See Slim tool reference.

MCP Client configuration

For setup instructions specific to your editor or agent (e.g. Antigravity, Claude Code, Cursor, VS Code), please see our Client Configurations Guide.

Your first prompt

Enter the following prompt in your MCP Client to check if everything is working:

Check the performance of https://brave.com

Your MCP client should open the browser and record a performance trace.

Tools

If you run into any issues, checkout our troubleshooting guide. See the full Tool reference for a complete list of all supported MCP capabilities.

Configuration

Find the complete list of server parameters (e.g., --headless, --isolated, --slim) and how to configure WebSocket connections in the Configuration Guide.

Advanced usage

For advanced features such as handling concurrent sessions, persistent user data directories, connecting to a running Brave instance instead of starting a new one, or debugging on Android, see our Advanced Usage Guide.

Known limitations

See Troubleshooting.

Integrating as a browser subagent

If you are developing agentic tooling and want to provide an integrated browser subagent as part of your product, we recommend building on top of Brave DevTools for agents.

For a reference implementation, see the Gemini CLI browser agent documentation.
