Common questions
Is Yad Agent 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 (0.1.1) reached the registry 2 months 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?
In the same category: GitHub, Desktop Commander, Cloudflare MCP

yad-agent-mcp
An MCP server that lets an AI agent drive Yad, a local, privacy-first browser-automation companion, in the user's real, already-logged-in browser.
This is a thin wrapper: it does not run a browser itself. It talks to Yad's existing local HTTP API on 127.0.0.1:3747 over stdio, so any MCP-compatible client (Claude Code, Cursor, Claude Desktop, etc.) can ask Yad to navigate, read a page, or carry out a plain-language browser task, and get the result back.
Local-only by design. This is not a hosted or remote MCP server. It only works on a machine that already has Yad installed and running (extension in Chrome/Edge/Brave, companion app active). If you're looking for a server your agent can call over the internet with zero local setup, this isn't that, and honestly, nothing that drives a user's real logged-in browser session should be.
Requirements
- Yad installed and running (Chrome, Edge, or Brave extension plus the local companion app)
- Node.js 20+
Install
npm install -g yad-agent-mcpConfigure your MCP client
Claude Code (.mcp.json or claude mcp add):
{"mcpServers": { "yad-agent": { "command": "yad-agent-mcp" } } }
If Yad's companion runs on a non-default port, set YAD_COMPANION_URL (defaults to http://127.0.0.1:3747).
Tools
| Tool | What it does |
|---|---|
yad_status | Checks whether Yad's companion is running and connected to the browser. Call this first. |
yad_navigate | Opens a URL in the browser tab Yad controls. |
yad_capture | Reads the URL, title, visible text, and links of the current page. |
yad_run_goal | Gives Yad a plain-language task ("find the price of the first item", "click the login button") and waits for the result. |
yad_last_result | Re-reads the result of the most recent yad_run_goal call. |
Yad cannot check out, pay, or place an order without the user's own confirmation, regardless of what an agent asks it to do. This wrapper doesn't add or remove that limit, it's enforced by Yad itself.
