CLI over MCP: a small Chrome DevTools experiment in Copilot CLI
The author experimented with two methods for controlling a browser with AI: direct Chrome DevTools MCP and a custom CLI skill using mcp2cli. The direct MCP approach consumed a significant amount of tokens upfront for context, while the CLI method aimed to reduce token waste by treating browser controls as discoverable commands. Although direct MCP yielded a faster single run, the CLI approach showed more stable message growth over multiple attempts. AI
IMPACT This experiment highlights potential token efficiency gains for AI agents controlling browsers, which could impact development costs and performance.
