walkerOS Source Browser MCP server

@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

Tool	Description
generate_tagging	Turn structured input into data-elb attributes and an example HTML snippet
parse_tagging	Parse an HTML snippet and extract the walkerOS events and globals it produces
validate_tagging	Check 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.
