Doppel: A Low-Token MCP Server for Real Browser Automation
No_Airport_1450 · reddit · 2026-08-03
To solve the issues of excessive token consumption and bot walls in existing browser MCPs, a developer has released Doppel. It is an MCP server paired with a browser extension that allows AI agents to drive the user's actual Chrome profile.
Key Features:
- Low-token & Fast: Reads pages via the accessibility tree instead of taking screenshots, drastically cutting token usage and increasing speed.
- Anti-bot: Connects to the real browser via an extension, preventing the navigator.webdriver flag from triggering bot walls.
- Local & Debug-friendly: Runs entirely locally and surfaces network requests and console errors directly to the agent.
