walkerOS Source 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. Runs locally, 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"]
    }
  }
}

In Claude Code you can install the walkerOS plugin instead, which registers this server along with the flow development server and the walkerOS skills:

/plugin marketplace add elbwalker/walkerOS
/plugin install walkeros@elbwalker

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 orphan actions, missing entities, unknown triggers, and entities without actions

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