Could you build this?
Partial An MCP server wrapper is easy to write, but creating a reliable browser action memory and DOM extraction layer that significantly speeds up agent execution requires specialized browser automation heuristics and caching architectures.
What it would actually take: The architecture requires an MCP server integrating with a headless browser runner (Playwright/Puppeteer) and a persistent state cache (e.g., Redis or SQLite). The hard part is building reliable web DOM abstraction, diffing algorithms, and semantic action recording that accurately compresses page state and bypasses repetitive multi-step vision loops across changing web layouts. This requires strong expertise in browser internals, DOM tree parsing, and AI context optimization.
