A standalone [`brave-devtools`](docs/cli.md) CLI is included too.\n\n## Install in one command\n\n### Claude Code\n\n```bash\nclaude mcp add brave-devtools --scope user -- npx -y brave-mcp@latest\n```\n\n### Cursor\n\n```bash\ncursor --add-mcp '{\"name\":\"brave-devtools\",\"command\":\"npx\",\"args\":[\"-y\",\"brave-mcp@latest\"]}'\n```\n\n### Codex\n\n```bash\ncodex mcp add brave-devtools -- npx -y brave-mcp@latest\n```\n\n### OpenCode\n\n```bash\nopencode mcp add brave-devtools -- npx -y brave-mcp@latest\n```\n\nRestart your client, then try this prompt:\n\n> Open my app in Brave. Find console errors and failed network requests, inspect the accessibility tree, run Lighthouse, and explain the highest-impact issue.\n\n## Why use this instead of Chrome DevTools MCP?\n\n| Capability                               | `brave-mcp`                             | `chrome-devtools-mcp`                |\n| ---------------------------------------- | --------------------------------------- | ------------------------------------ |\n| Browser launched and discovered natively | Brave Release, Beta, and Nightly        | Chrome Stable, Beta, Dev, and Canary |\n| Attach to an existing browser            | Brave profiles, HTTP, or WebSocket      | Chrome profiles, HTTP, or WebSocket  |\n| Upstream DevTools features               | Full parity; currently 0 commits behind | Source implementation                |\n| Usage telemetry                          | Disabled by default                     | Enabled by default                   |\n| Standalone CLI                           | `brave-devtools`                        | `chrome-devtools`                    |\n\nUse [Chrome DevTools MCP](https://github.com/ChromeDevTools/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.\n\n## [Tool reference](./docs/tool-reference.md) | [Changelog](./CHANGELOG.md) | [Contributing](./CONTRIBUTING.md) | [Troubleshooting](./docs/troubleshooting.md) | [Design principles](./docs/design-principles.md)\n\n## Key features\n\n- **Get performance insights**: Uses [Chrome\n  DevTools](https://github.com/ChromeDevTools/devtools-frontend) to record\n  traces and extract actionable performance insights.\n- **Advanced browser debugging**: Analyze network requests, take screenshots and\n  check browser console messages (with source-mapped stack traces).\n- **Reliable automation**. Uses\n  [puppeteer](https://github.com/puppeteer/puppeteer) to automate actions in\n  Brave and automatically wait for action results.\n\n## Disclaimers\n\n`brave-mcp` exposes content of the browser instance to the MCP clients\nallowing them to inspect, debug, and modify any data in the browser or DevTools.\nAvoid sharing sensitive or personal information that you don't want to share with\nMCP clients.\n\n`brave-mcp` officially supports the current Brave release. Beta and Nightly channels can be selected explicitly.\n\nPerformance tools may send trace URLs to the Google CrUX API to fetch real-user\nexperience data. This helps provide a holistic performance picture by\npresenting field data alongside lab data. This data is collected by the [Chrome\nUser Experience Report (CrUX)](https://developer.chrome.com/docs/crux). To disable\nthis, run with the `--no-performance-crux` flag.\n\n## **Usage statistics**\n\nUsage statistics collection is **disabled by default** in this fork. It can be enabled explicitly with `--usage-statistics`, which uses the upstream Google Clearcut implementation:\n\n```json\n\"args\": [\"-y\", \"brave-mcp@latest\", \"--usage-statistics\"]\n```\n\nWhen enabled, Google handles this data in accordance with the [Google Privacy Policy](https://policies.google.com/privacy). Collection remains disabled if `BRAVE_DEVTOOLS_MCP_NO_USAGE_STATISTICS` or `CI` is set.\n\n## Update checks\n\nBy default, the server periodically checks the npm registry for updates and logs a notification when a newer version is available.\nYou can disable these update checks by setting `BRAVE_DEVTOOLS_MCP_NO_UPDATE_CHECKS`.\n\n## Requirements\n\n- [Node.js](https://nodejs.org/) [LTS](https://github.com/nodejs/Release#release-schedule) version.\n- [Brave](https://brave.com/download/) current release or newer.\n- [npm](https://www.npmjs.com/)\n\n## Getting started\n\nAdd the following config to your MCP client:\n\n```json\n{\n  \"mcpServers\": {\n    \"brave-devtools\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"brave-mcp@latest\"]\n    }\n  }\n}\n```\n\n> [!NOTE]\n> Using `brave-mcp@latest` ensures that your MCP client will always use the latest version of the Brave DevTools MCP server.\n\nIf you are interested in doing only basic browser tasks, use the `--slim` mode:\n\n```json\n{\n  \"mcpServers\": {\n    \"brave-devtools\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"brave-mcp@latest\", \"--slim\", \"--headless\"]\n    }\n  }\n}\n```\n\nSee [Slim tool reference](./docs/slim-tool-reference.md).\n\n### MCP Client configuration\n\n<details>\n  <summary>Amp</summary>\n  Follow https://ampcode.com/manual#mcp and use the config provided above. You can also install the Brave DevTools MCP server using the CLI:\n\n```bash\namp mcp add brave-devtools -- npx brave-mcp@latest\n```\n\n</details>\n\n<details>\n  <summary>Antigravity</summary>\n\nTo use the Brave DevTools MCP server follow the instructions from <a href=\"https://antigravity.google/docs/mcp\">Antigravity's docs</a> to install a custom MCP server. Add the following config to the MCP servers config:\n\n```bash\n{\n  \"mcpServers\": {\n    \"brave-devtools\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"brave-mcp@latest\",\n        \"--browser-url=http://127.0.0.1:9222\"\n      ]\n    }\n  }\n}\n```\n\nThis will make the Brave DevTools MCP server automatically connect to the browser that Antigravity is using. If you are not using port 9222, make sure to adjust accordingly.\n\nBrave DevTools MCP will not start the browser instance automatically using this approach because the Brave DevTools MCP server connects to Antigravity's built-in browser. If the browser is not already running, you have to start it first by clicking the Chrome icon at the top right corner.\n\n</details>\n\n<details>\n  <summary>Bob</summary>\n\nFollow the <a href=\"https://bob.ibm.com/docs/ide/configuration/mcp/mcp-in-bob\">IBM Bob MCP guide</a> and add the Brave DevTools MCP server to your Bob MCP configuration. Use the global config (`~/.bob/mcp.json`) to apply it across all workspaces, or a project config (`.bob/mcp.json`) to scope it to one project:\n\n```json\n{\n  \"mcpServers\": {\n    \"brave-devtools\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"brave-mcp@latest\"]\n    }\n  }\n}\n```\n\nYou can edit these files from **Bob panel → Settings → MCP → Edit Global MCP** (or **Edit Project MCP**). Bob hot-reloads on save. Once the server appears in the MCP tab, switch to the **🌎 Browser Dev** mode to get guided browser debugging directly in Bob.\n\n</details>\n\n<details>\n  <summary>Claude Code</summary>\n\n**Install via CLI (MCP only)**\n\nUse the Claude Code CLI to add the Brave DevTools MCP server (<a href=\"https://code.claude.com/docs/en/mcp\">guide</a>):\n\n```bash\nclaude mcp add brave-devtools --scope user npx brave-mcp@latest\n```\n\n**Install as a Plugin (MCP + Skills)**\n\n> [!NOTE]\n> If you already had Brave DevTools MCP installed previously for Claude Code, make sure to remove it first from your installation and configuration files.\n\nTo install Brave DevTools MCP with skills, add the marketplace registry in Claude Code:\n\n```sh\n/plugin marketplace add triuzzi/brave-devtools-mcp\n```\n\nThen, install the plugin:\n\n```sh\n/plugin install brave-devtools-mcp@brave-devtools-plugins\n```\n\nRestart Claude Code to have the MCP server and skills load (check with `/skills`).\n\n> [!TIP]\n> If the plugin installation fails with a `Failed to clone repository` error (e.g., HTTPS connectivity issues behind a corporate firewall), see the [troubleshooting guide](./docs/troubleshooting.md#claude-code-plugin-installation-fails-with-failed-to-clone-repository) for workarounds, or use the CLI installation method above instead.\n\n</details>\n\n<details>\n  <summary>Cline</summary>\n  Follow https://docs.cline.bot/mcp/configuring-mcp-servers and use the config provided above.\n</details>\n\n<details>\n  <summary>Codex</summary>\n  Follow the <a href=\"https://developers.openai.com/codex/mcp/#configure-with-the-cli\">configure MCP guide</a>\n  using the standard config from above. You can also install the Brave DevTools MCP server using the Codex CLI:\n\n```bash\ncodex mcp add brave-devtools -- npx brave-mcp@latest\n```\n\n**On Windows 11**\n\nConfigure the Brave install location and increase the startup timeout by updating `.codex/config.toml` and adding the following `env` and `startup_timeout_ms` parameters:\n\n```\n[mcp_servers.brave-devtools]\ncommand = \"cmd\"\nargs = [\n    \"/c\",\n    \"npx\",\n    \"-y\",\n    \"brave-mcp@latest\",\n]\nenv = { SystemRoot=\"C:\\\\Windows\", PROGRAMFILES=\"C:\\\\Program Files\" }\nstartup_timeout_ms = 20_000\n```\n\n</details>\n\n<details>\n  <summary>Command Code</summary>\n\nUse the Command Code CLI to add the Brave DevTools MCP server (<a href=\"https://commandcode.ai/docs/mcp\">MCP guide</a>):\n\n```bash\ncmd mcp add brave-devtools --scope user npx brave-mcp@latest\n```\n\n</details>\n\n<details>\n  <summary>Copilot CLI</summary>\n\nStart Copilot CLI:\n\n```\ncopilot\n```\n\nStart the dialog to add a new MCP server by running:\n\n```\n/mcp add\n```\n\nConfigure the following fields and press `CTRL+S` to save the configuration:\n\n- **Server name:** `brave-devtools`\n- **Server Type:** `[1] Local`\n- **Command:** `npx -y brave-mcp@latest`\n\n</details>\n\n<details>\n  <summary>Copilot / VS Code</summary>\n\n**Install as a Plugin (Recommended)**\n\nThe easiest way to get up and running is to install `brave-mcp` as an agent plugin.\nThis bundles the **MCP server** and all **skills** together, so your agent gets both the tools\nand the expert guidance it needs to use them effectively.\n\n1.  Open the **Command Palette** (`Cmd+Shift+P` on macOS or `Ctrl+Shift+P` on Windows/Linux).\n2.  Search for and run the **Chat: Install Plugin From Source** command.\n3.  Paste in our repository name: `triuzzi/brave-devtools-mcp`.\n\nThat's it! Your agent is now supercharged with Brave DevTools capabilities.\n\n---\n\n**Install as an MCP Server (MCP only)**\n\n**Click the button to install:**\n\n[<img src=\"https://img.shields.io/badge/VS_Code-VS_Code?style=flat-square&label=Install%20Server&color=0098FF\" alt=\"Install in VS Code\">](https://vscode.dev/redirect/mcp/install?name=io.github.triuzzi%2Fbrave-mcp&config=%7B%22command%22%3A%22npx%22%2C%22args%22%3A%5B%22-y%22%2C%22brave-mcp%22%5D%2C%22env%22%3A%7B%7D%7D)\n\n[<img src=\"https://img.shields.io/badge/VS_Code_Insiders-VS_Code_Insiders?style=flat-square&label=Install%20Server&color=24bfa5\" alt=\"Install in VS Code Insiders\">](https://insiders.vscode.dev/redirect?url=vscode-insiders%3Amcp%2Finstall%3F%257B%2522name%2522%253A%2522io.github.triuzzi%252Fbrave-mcp%2522%252C%2522config%2522%253A%257B%2522command%2522%253A%2522npx%2522%252C%2522args%2522%253A%255B%2522-y%2522%252C%2522brave-mcp%2522%255D%252C%2522env%2522%253A%257B%257D%257D%257D)\n\n**Or install manually:**\n\nFollow the VS Code [MCP configuration guide](https://code.visualstudio.com/docs/copilot/chat/mcp-servers#_add-an-mcp-server) using the standard config from above, or use the CLI:\n\nFor macOS and Linux:\n\n```bash\ncode --add-mcp '{\"name\":\"io.github.triuzzi/brave-devtools-mcp\",\"command\":\"npx\",\"args\":[\"-y\",\"brave-mcp\"],\"env\":{}}'\n```\n\nFor Windows (PowerShell):\n\n```powershell\ncode --add-mcp '{\"\"\"name\"\"\":\"\"\"io.github.triuzzi/brave-devtools-mcp\"\"\",\"\"\"command\"\"\":\"\"\"npx\"\"\",\"\"\"args\"\"\":[\"\"\"-y\"\"\",\"\"\"brave-mcp\"\"\"]}'\n```\n\n</details>\n\n<details>\n  <summary>Cursor</summary>\n\n**Click the button to install:**\n\n[<img src=\"https://cursor.com/deeplink/mcp-install-dark.svg\" alt=\"Install in Cursor\">](https://cursor.com/en/install-mcp?name=brave-devtools&config=eyJjb21tYW5kIjoibnB4IC15IGJyYXZlLW1jcEBsYXRlc3QifQ%3D%3D)\n\n**Or install manually:**\n\nGo to `Cursor Settings` -> `MCP` -> `New MCP Server`.

For example:\n\n```json\n{\n  \"mcpServers\": {\n    \"brave-devtools\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"brave-mcp@latest\",\n        \"--channel=nightly\",\n        \"--headless=true\",\n        \"--isolated=true\"\n      ]\n    }\n  }\n}\n```\n\n### Connecting via WebSocket with custom headers\n\nYou can connect directly to a Brave WebSocket endpoint and include custom headers (e.g., for authentication):\n\n```json\n{\n  \"mcpServers\": {\n    \"brave-devtools\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"brave-mcp@latest\",\n        \"--wsEndpoint=ws://127.0.0.1:9222/devtools/browser/<id>\",\n        \"--wsHeaders={\\\"Authorization\\\":\\\"Bearer YOUR_TOKEN\\\"}\"\n      ]\n    }\n  }\n}\n```\n\nTo get the WebSocket endpoint from a running Brave instance, visit `http://127.0.0.1:9222/json/version` and look for the `webSocketDebuggerUrl` field.\n\nYou can also run `npx brave-mcp@latest --help` to see all available configuration options.\n\n## Concepts\n\n### Concurrent sessions\n\nMost MCP clients start one Brave DevTools MCP server per conversation.\nBy default, the server runs with `--pageIdRouting` enabled, making `pageId` a\nrequired parameter on page-scoped tools (such as `click`, `fill`, `navigate_page`,\n`take_snapshot`, etc.) so multiple agents or subagents sharing a server instance can\nroute tool calls directly to the specific tab they are working with.\n\nFor `evaluate_script`, `pageId` is required by default for targeting pages, but\nbecomes optional when `--categoryExtensions` is enabled so that `serviceWorkerId`\ncan be specified instead to evaluate inside an extension background service worker.\n\nTo disable this behavior and default to the currently selected page, pass\n`--no-page-id-routing`.\n\n```json\n{\n  \"mcpServers\": {\n    \"brave-devtools\": {\n      \"command\": \"npx\",\n      \"args\": [\"-y\", \"brave-mcp@latest\"]\n    }\n  }\n}\n```\n\nIf you run multiple independent MCP client sessions and want each session to\nlaunch its own temporary Brave profile, also pass `--isolated`. This avoids\nsharing the default Brave DevTools MCP user data directory between those\nserver instances.\n\n### User data directory\n\nBy default, `brave-mcp` starts the Brave release channel using the following user\ndata directory:\n\n- Linux / macOS: `$HOME/.cache/brave-devtools-mcp/brave-profile`\n- Windows: `%USERPROFILE%\\.cache\\brave-devtools-mcp\\brave-profile`\n\nFor non-release channels, the channel name is appended to the directory name, for example\n`brave-profile-nightly`.\n\nThe user data directory is not cleared between runs and is reused for subsequent\nruns with the same channel. Only one browser can use it at a time. Set the `isolated`\noption to `true` to use a temporary user data directory instead which will be cleared\nautomatically after the browser is closed.\n\n### Connecting to a running Brave instance\n\nBy default, the Brave DevTools MCP server will start a new Brave instance with a dedicated profile. This might not be ideal in all situations:\n\n- If you would like to maintain the same application state when alternating between manual site testing and agent-driven testing.\n- When the MCP needs to sign into a website. Some accounts may prevent sign-in when the browser is controlled via WebDriver (the default launch mechanism for the Brave DevTools MCP server).\n- If you're running your LLM inside a sandboxed environment, but you would like to connect to a Brave instance that runs outside the sandbox.\n\nIn these cases, start Brave first and let the Brave DevTools MCP server connect to it. There are two ways to do so:\n\n- **Automatic connection**: best for sharing state between manual and agent-driven testing.\n- **Manual connection via remote debugging port**: best when running inside a sandboxed environment.\n\n#### Automatically connecting to a running Brave instance\n\n**Step 1:** Set up remote debugging in Brave\n\nIn Brave, do the following to set up remote debugging:\n\n1.  Navigate to `brave://inspect/#remote-debugging` to enable remote debugging.\n2.  Follow the dialog UI to allow or disallow incoming debugging connections.\n\n**Step 2:** Configure Brave DevTools MCP server to automatically connect to a running Brave instance\n\nTo connect the `brave-mcp` server to the running Brave instance, use\n`--autoConnect` command line argument for the MCP server.\n\nThe following code snippet is an example configuration for gemini-cli:\n\n```json\n{\n  \"mcpServers\": {\n    \"brave-devtools\": {\n      \"command\": \"npx\",\n      \"args\": [\"brave-mcp@latest\", \"--autoConnect\"]\n    }\n  }\n}\n```\n\n**Step 3:** Test your setup\n\nMake sure your browser is running. Open gemini-cli and run the following prompt:\n\n```none\nCheck the performance of https://developers.chrome.com\n```\n\n> [!NOTE]\n> The <code>autoConnect</code> option requires the user to start Brave. If the user has multiple active profiles, the MCP server connects to Brave's default profile and can access all open windows for that profile.\n\nThe Brave DevTools MCP server will try to connect to your running Brave\ninstance. It shows a dialog asking for user permission.\n\nClicking **Allow** results in the Brave DevTools MCP server opening\n[developers.chrome.com](http://developers.chrome.com) and taking a performance\ntrace.\n\n#### Manual connection using port forwarding\n\nYou can connect to a running Brave instance by using the `--browser-url` option. This is useful if you are running the MCP server in a sandboxed environment that does not allow starting a new Brave instance.\n\nHere is a step-by-step guide on how to connect to a running Brave instance:\n\n**Step 1: Configure the MCP client**\n\nAdd the `--browser-url` option to your MCP client configuration. The value of this option should be the URL of the running Brave instance. `http://127.0.0.1:9222` is a common default.\n\n```json\n{\n  \"mcpServers\": {\n    \"brave-devtools\": {\n      \"command\": \"npx\",\n      \"args\": [\"brave-mcp@latest\", \"--browser-url=http://127.0.0.1:9222\"]\n    }\n  }\n}\n```\n\n**Step 2: Start the Brave browser**\n\n> [!WARNING]\n> Enabling the remote debugging port opens up a debugging port on the running browser instance. Any application on your machine can connect to this port and control the browser. Make sure that you are not browsing any sensitive websites while the debugging port is open.\n\nStart the Brave browser with the remote debugging port enabled. Make sure to close any running Brave instances before starting a new one with the debugging port enabled. The port number you choose must be the same as the one you specified in the `--browser-url` option in your MCP client configuration.\n\nUse a dedicated user data directory when enabling the remote debugging port so your regular browsing profile and data are not exposed to the debugging session.\n\n**macOS**\n\n```bash\n/Applications/Brave\\ Browser.app/Contents/MacOS/Brave\\ Browser --remote-debugging-port=9222 --user-data-dir=/tmp/brave-profile-release\n```\n\n**Linux**\n\n```bash\n/usr/bin/brave-browser --remote-debugging-port=9222 --user-data-dir=/tmp/brave-profile-release\n```\n\n**Windows**\n\n```bash\n\"C:\\Program Files\\BraveSoftware\\Brave-Browser\\Application\\brave.exe\" --remote-debugging-port=9222 --user-data-dir=\"%TEMP%\\brave-profile-release\"\n```\n\n**Step 3: Test your setup**\n\nAfter configuring the MCP client and starting the Brave browser, you can test your setup by running a simple prompt in your MCP client:\n\n```\nCheck the performance of https://developers.chrome.com\n```\n\nYour MCP client should connect to the running Brave instance and receive a performance report.\n\nIf you hit VM-to-host port forwarding issues, see the “Remote debugging between virtual machine (VM) and host fails” section in [`docs/troubleshooting.md`](./docs/troubleshooting.md#remote-debugging-between-virtual-machine-vm-and-host-fails).\n\nFor more details on remote debugging, see the [Chromium DevTools documentation](https://developer.chrome.com/docs/devtools/remote-debugging/).\n\n### Debugging Chrome on Android\n\nPlease consult [these instructions](./docs/debugging-android.md).\n\n## Known limitations\n\nSee [Troubleshooting](./docs/troubleshooting.md).\n\n## Integrating as a browser subagent\n\nIf 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.\n\nFor a reference implementation, see the [Gemini CLI browser agent documentation](https://geminicli.com/docs/core/subagents/#browser-agent).\n",
