Connects Claude and other MCP clients to Plasmate's browser engine instead of traditional headless Chrome. Exposes six core tools: fetch_page and extract_text for quick content retrieval, open_page for persistent sessions, click and evaluate for interaction, and close_page for cleanup. The main hook is token efficiency. Plasmate returns a Semantic Object Model instead of raw HTML or DOM dumps, which the maintainers benchmark at 16x fewer tokens. You'd reach for this when you're building agents that need to browse the web repeatedly and token costs or context windows are tight. Requires installing both the npm wrapper and the Plasmate engine itself via pip, cargo, or homebrew.
