    }
  }
}

Run this in your terminal

claude mcp add h5-devtools -- npx -y h5-devtools-mcp

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

Common questions

Is H5 DevTools MCP safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (0.1.2) reached the registry 17 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need Node.js on your computer.

What can I use instead?

h5-devtools-mcp

English | 简体中文

An MCP server that lets coding agents (Claude Code, Codex, Cursor…) debug H5 pages running inside Android WebViews on real devices — read console output and uncaught exceptions, and run JavaScript in the page, without opening chrome://inspect.

Status: v0.1, early. Android only.

How it works

Coding agent ──MCP (stdio)──▶ h5-devtools-mcp ──adb forward──▶ webview_devtools_remote_<pid> ──CDP──▶ WebView page

Every debuggable WebView exposes a Chrome DevTools Protocol endpoint on an abstract unix socket. The server discovers those sockets over adb (the same way chrome://inspect does), forwards them to local ports, and connects with CDP.

Requirements

Node.js 18+
adb on your PATH (or set ADB_PATH)
An Android device with USB debugging enabled
The app must enable WebView debugging (debug builds usually do):

WebView.setWebContentsDebuggingEnabled(true);

Setup

# Claude Code

claude mcp add h5-devtools -- npx -y h5-devtools-mcp

Other MCP clients (Cursor, Codex…) take the same command: npx -y h5-devtools-mcp.

From source

git clone https://github.com/xianguoGou/h5-devtools-mcp.git

cd h5-devtools-mcp npm install && npm run build claude mcp add h5-devtools -- node /absolute/path/to/h5-devtools-mcp/dist/index.js

Tools

Tool	What it does
`list_targets`	List debuggable pages: app package, title, URL, visibility
`attach`	Connect to a page and start buffering console output
`get_console`	Read buffered entries, filtered by level / keyword / `exclude_keywords`, incrementally via `since_seq`
`evaluate_js`	Run a JavaScript expression in the page and return the result (promises are awaited)
`detach`	Disconnect from a page

Output is designed to be token-cheap: compact one-line entries, long messages truncated, and since_seq so an agent only reads what's new instead of re-reading the whole buffer on every turn.

Example

> list_targets

id: R5CT1234/webview_devtools_remote_8812/3A1F… app: com.example.app (pid 8812) on SM-S9180 title: "Order" url: https://m.example.com/order

get_console { "levels": ["error"] }

#41 10:32:01.123 [error exception] TypeError: Cannot read properties of undefined (reading 'price') at https://m.example.com/assets/index-8f2a.js:1:48213 next since_seq: 57

Troubleshooting

"no debuggable WebView found" — the app hasn't enabled WebView debugging, or no WebView is alive yet. Open the H5 page first.
"debugger in use" — only one debugger can attach to a page. Close the chrome://inspect DevTools window.
"unauthorized" — accept the USB debugging prompt on the device.

Known limitations

Debugger-in-use detection is best-effort. It relies on /json/list omitting webSocketDebuggerUrl. Recent Chromium accepts several CDP clients per page, so attach may succeed alongside an open DevTools window; older WebViews may still refuse.
`list_targets` can take ~3s per unresponsive app. Sockets are queried one by one with a 3s timeout, and Android freezes background apps, so their WebView sockets stop answering. attach only re-checks the target's own socket and stays fast.
`evaluate_js` runs with the page's full privileges — it can read cookies, storage and tokens, and change page state. Keep it behind your agent's tool-permission prompt.
The e2e script expects port 9333 to be free. If a previous run left a headless Chromium behind, it attaches to that one; kill it first.

Development

The e2e test uses a fake adb and headless Chromium in place of a phone:

npm run build

CHROME=/path/to/chrome npm run test:e2e
