Dan Shipper 把 Stainless 被收购这件事,讲成了一个信号:API、SDK、MCP 这些看起来不起眼的中间层,现在已经值钱了。
他从和 Alex Rattray 的对谈里提炼出来的设计判断也很直白:未来给 agent 用的接口,可能不是塞一堆工具进去,而是让模型自己写代码、跑 SDK、遇到问题再查文档。
他还提到 Stainless 处理大 API 的一个实用做法——dynamic mode:只给模型三个工具(列出接口、了解接口、执行接口),多花几轮对话,但 context 窗口干净很多。
Dan 说,Anthropic 收购了 Stainless,这家公司最大的客户是 OpenAI 和 Google。
他从对谈中提炼了几个关键要点:MCP server 设计要精简;用 dynamic mode 管理复杂 API;MCP server 可以当业务 copilot 用;用 Claude Code 给公司搭一个知识大脑。
他认为 MCP 的未来是 code execution + doc search,而不是一个越来越长的工具列表。
Dan Shipper frames the Stainless acquisition as proof that the AI stack's boring middle layer—APIs, SDKs, MCP servers—has become strategically valuable.
His strongest design takeaway from Alex Rattray's thinking: the winning interface for agents may converge toward code execution plus documentation lookup, instead of giant menus of brittle tools.
He also highlights the practical pattern Stainless uses for large APIs: 'dynamic mode' with just three tools—list endpoints, learn about one, execute it—which trades extra turns for dramatically smaller context windows.
Anthropic just acquired developer tool startup @StainlessAPI, whose biggest customers were OpenAI and Google.
Highlights include: Design MCP servers to be lean and precise. Make complex APIs manageable with dynamic mode. MCP servers as business copilots. Create a 'brain' for your company with Claude Code. The future of MCP is code execution.
Alex essentially walks me through the design thinking for building APIs, SDKs, and MCP servers that Anthropic paid a reported $300 million for.
