mcp vs plasmate

Q: Which is better, mcp or plasmate?

By GitHub stars, mcp has more community adoption, but the best choice depends on your specific use case.

mcp: Browser MCP is an MCP server and Chrome extension that enables AI applications like VS Code, Claude, and Cursor to automate your browser. It performs automation locally, leveraging your existing browser profile for speed, privacy, and stealth.; 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.
