mcp-chrome vs plasmate

mcp-chrome: Chrome MCP Server transforms your Chrome browser into an AI-controlled automation tool by exposing its functionality via the Model Context Protocol. It allows LLMs and AI assistants like Claude to interact with your browser, leveraging your existing user habits and login states for complex tasks.; plasmate: Plasmate compiles HTML into a Semantic Object Model (SOM), a structured representation that LLMs can reason about directly. It runs JavaScript via V8, supports Puppeteer via CDP, and produces output that is 10-800x smaller than raw HTML. It is purpose-built for AI agent pipelines, with MCP, Vercel AI SDK integrations, and over 60 ecosystem integrations.
