Overview

Description from the maker (original English)

Generate, parse, and validate walkerOS data-elb HTML tagging attributes

PopNx MCP’s three pillars

These three are never merged into one score: opinions, measurements and popularity are different things.

What you can do with it

We have not written a plain-language summary for this one yet. Below are the facts we read from the registry.

  • Connection: Runs on your computer
  • Transport: stdio
  • Category: Web & browsers

Install

Pick the AI app you use, then copy the settings.

You need

  • npmNode.js installed (for the npx command)

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "source-browser": {
      "command": "npx",
      "args": [
        "-y",
        "@walkeros/mcp-source-browser"
      ]
    }
  }
}

Run this in your terminal

claude mcp add source-browser -- npx -y @walkeros/mcp-source-browser

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

{
  "mcpServers": {
    "source-browser": {
      "command": "npx",
      "args": [
        "-y",
        "@walkeros/mcp-source-browser"
      ]
    }
  }
}

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "source-browser": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@walkeros/mcp-source-browser"
      ]
    }
  }
}

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

Basic checksi

We check information anyone can see; we have not read the code. Checks that do not apply are left out of the count. · Checked Nov 5, 2026

  • ✓ Pass

    Maker matches the repo

  • Published to the registry more recently than 11% of the other 9 servers in this category
  • Basic checks equal to or better than 100% of the other 9 servers in this category

Compared only with servers in this prototype, not the whole registry.

Common questions

Is walkerOS Source Browser safe?

It passed 3 of 3 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 yesterday, and the latest version (4.5.0) 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: Browser Use, Chrome DevTools MCP, MCP Server Browser

@walkeros/mcp-source-browser

Model Context Protocol server for walkerOS HTML tagging. Generates, parses, and validates data-elb attributes using real DOM parsing, so an AI assistant can tag a page and check its own work. It runs locally and needs no account or API token.

Documentation • NPM Package • Source Code

Installation

The server runs over stdio and is started by your MCP client. Add it to the client's configuration:

{

"mcpServers": { "walkeros-source-browser": { "command": "npx", "args": ["@walkeros/mcp-source-browser"] } } }

The walkerOS Claude Code plugin registers the flow servers and the walkerOS skills. It does not register this server, so in Claude Code add it to the configuration as above too.

To install the binary directly:

npm install @walkeros/mcp-source-browser

Quick start

Ask your assistant to tag a page, for example: "Generate walkerOS tagging for a product card with name and price". It calls generate_tagging and returns ready-to-paste data-elb attributes.

Tools

ToolDescription
generate_taggingTurn structured input into data-elb attributes and an example HTML snippet
parse_taggingParse an HTML snippet and extract the walkerOS events and globals it produces
validate_taggingCheck tagging for empty entity names, orphan actions, unknown triggers, orphan properties, and entities without actions

All three accept an optional prefix to match a custom attribute prefix, which defaults to data-elb.
