Rod seems to be about automating the local browser itself via MCP, through which you can try to self-automate websites loaded in the browser. Interestingly, it seems Google nowadays has its own official implementation of this https://github.com/ChromeDevTools/chrome-devtools-mcp
WebMCP seems to be about the authors of websites being able to publish a list of custom built-in tools the page has available for LLM agents to call. Less like "Analyze the form elements and call the DOM APIs to set..." and more akin to "Call the submitInformation(...) tool the website told us about over WebMCP".
