MCP服务器施加隐藏的上下文税,消耗token并增加成本

对25个流行的模型上下文协议(MCP)服务器的最新分析显示,工具模式(tool schemas)会施加一种显著且通常未披露的“上下文税”。这些模式被注入到每个模型请求中,占用了宝贵的上下文窗口空间并增加了成本。研究发现,这种开销的变化高达544倍,每次请求的token消耗量从35个到超过19,000个不等,其中notion-mcp和github等组合在用户输入任何内容之前就已超过23,000个token。分析还发现了安全问题,许多服务器读取了秘密环境变量,一些服务器表现出网络出口到意想不到的域,或捆绑了模糊其网络活动的最小化代码。 AI

    <p>Every MCP server you connect ships a set of tool-definition schemas. Those schemas get injected into <strong>every single model request</strong> for the whole session — before you ask the agent anything. That's a fixed tax on your context window and your bill, and no MCP direc…
