把浏览器工作交给你——一个为你的代理驱动页面的MCP服务器。

你的代理根本不应该打开浏览器。浏览器任务会覆盖整个——URL， 目标，以及证明它的检查——循环在服务器上运行。一个工具调用代替 二十。三秒而不是一分钟。一分钱代替边境模型的上下文。而且 从不虚构目标：它从页面实际拥有的内容中挑选，服务器拒绝，而不是 猜测。

花了多少钱。 一整天一分钱，一分钱就是全部：

快速开始

三条命令，然后重启客户端。

install.py 查找 WorkBuddy、Claude Code、Claude Desktop、Codex CLI、Cursor、VS Code、Cline， 风帆冲浪和双子座CLI，并编写每个人期望的格式——合并到你现有的 先配置并保存一个.bak。需要Python ≥3.10和任何Chromium系列浏览器。

重启客户端，然后说你想说的话：

你： 将此表格设置为3位成年人，勾选不间断，然后提交。 您的代理： browser_goal(goal=…, url=…, verify=[…]) — ** 一通**通话;页面被打开，随后

jev-ultrafast-mcp

Hand the browser work off — an MCP server that drives the page for your agent.

Your agent should not be opening the browser at all. A browser task goes over whole — the URL, the goal, and the check that proves it — and the loop runs on the server. One tool call instead of twenty. Three seconds instead of a minute. A cent instead of a frontier model’s context. And it never invents a target: it picks from what the page actually has, and the server refuses rather than guesses.

What it cost. A cent for the whole day, and a cent is all of it:

Quick start

Three commands, then restart your client.

git clone https://github.com/jiawei686/jev-ultrafast-mcp.git
cd jev-ultrafast-mcp
python3 -m venv .venv
.venv/bin/pip install -e .          # Windows: .venv\Scripts\pip install -e .

python scripts/install.py           # finds your MCP clients and writes their config

install.py looks for WorkBuddy, Claude Code, Claude Desktop, Codex CLI, Cursor, VS Code, Cline, Windsurf and Gemini CLI, and writes the format each one expects — merging into your existing config and saving a .bak first. Needs Python ≥ 3.10 and any Chromium-family browser.

Restart the client, and then just say what you want:

You: Set this form to 3 adults, tick Nonstop only, then submit it. Your agent: browser_goal(goal=…, url=…, verify=[…]) — one call; the page is opened and the loop runs server-side, and the result is checked by code afterwards. (what that costs)

You: Open example.com and tell me what the page says. Your agent: browser_open → reads the element table → answers — a look is not a task, so it does not need the model. (verbatim run)

Restarted and the tools are not there? Some clients make you approve the server once. In WorkBuddy that is Connectors → Custom connectors → Trust. The approval is remembered against the config itself, so if you later edit the config it asks once more.
