模型上下文协议（Model Context Protocol）：https://modelcontextprotocol.io/docs/getting-started/intro（MCP）是人工智能互操作性的基本构建模块之一，为 AI 模型提供了一种安全访问外部数据源和服务的方式。它就像管道，让聊天机器人可以访问你的日历、数据库或内部工具，而无需每次连接都由工程师来构建自定义管道。下周，该协议将迎来一次重大更新，虽然普通用户可能感觉不到，但它可能会对生态系统的发展产生重大影响。
Arcade 于六月筹集了 6000 万美元：https://www.businesswire.com/news/home/20260615229631/en/Arcade-Raises-$60M-to-Become-the-Secure-Action-Layer-Behind-Every-Production-AI-Agent，基于这样一个理念：大多数 AI 代理失败并不是因为底层模型薄弱，而是因为其周围的基础设施尚未准备好，而这正是本次更新试图解决的问题。本质上，MCP 正在改变处理会话 ID 的方式——服务器用来记住“啊，这是五秒前的同一段对话”的小令牌——以便服务器能够更轻松地在更大规模上运行。
正如 Arcade 创始工程师 Nate Barbettini 所说：
[在当前系统下] 第一次像 Claude 这样的 MCP 客户端连接到服务器时，它会发送一个“hello”：我是 Claude，这是我的版本，这是我的能力。服务器会回复自己的能力并返回一个会话 ID……从那以后，客户端在每次请求时都会发送该会话 ID，这样服务器就知道这是同一段对话。有时 ID 会过期，所以客户端必须注意到这一点，请求一个新的，然后继续……。

The Model Context Protocol：https://modelcontextprotocol.io/docs/getting-started/intro (MCP) is one of the basic building blocks of AI interoperability, giving AI models a secure way to access external data sources and services. It’s the plumbing that lets a chatbot reach into your calendar, your database, or your internal tools, instead of engineers building custom pipes for every connection. Next week, that protocol is getting a significant update, and while it might not be noticeable to end users, it could make a big difference in how the ecosystem develops.
The official spec：https://blog.modelcontextprotocol.io/posts/2026-07-28-release-candidate/ for the new version has been public since May, but we got an unusually clear explanation：https://www.arcade.dev/blog/mcp-going-stateless/ of the changes Monday morning from the folks at Arcade — a two-year-old startup that’s built its entire business around the work of getting AI agents to actually function inside real companies, letting them securely connect to and act on tools like Gmail, Slack, and Salesforce.
Arcade raised $60 million：https://www.businesswire.com/news/home/20260615229631/en/Arcade-Raises-$60M-to-Become-the-Secure-Action-Layer-Behind-Every-Production-AI-Agent in June based on the idea that most AI agents don’t fail because the underlying models are weak but because the infrastructure around them isn’t ready yet, and that’s what this update is trying to address. Essentially, MCP is changing the way it handles session IDs — the little tokens that servers use to remember “ah, this is the same conversation as five seconds ago” — so servers can operate more easily at a larger scale.
As Arcade founding engineer Nate Barbettini puts it:
[Under the current system] The first time an MCP client like Claude connects to a server, it sends a “hello”: I’m Claude, here’s my version, here are my capabilities. The server replies with its own capabilities and hands back a session ID… From then on, the client sends that session ID on every request so the server knows it’s the same conversation. Sometimes the ID expires, so the client has to notice, request a new one, and carry on….
Picture a real deployment. You’re running a server for millions of users, behind a load balancer whose entire job is to route each request to whatever server in the farm is free, sometimes in a different region. Now every one of those machines has to know about a session ID that some other machine handed out. It’s not impossible, but it’s a serious pain, and it fights the load balancer instead of working with it.
In other words, the current setup assumes one server remembers you, but real companies spread traffic across dozens of servers that don’t talk to each other by default, so today’s MCP servers have to do extra work just to keep track of who’s who. That’s been a significant headache for anyone running an MCP server at scale, and part of the reason we haven’t seen more companies ship large-scale, first-party MCP integrations despite all the hype around agentic AI this year.
Under the new system, the protocol will take a looser, “stateless” approach to session IDs on the server side, similar to how most ordinary websites already work, which should make the whole system a lot easier to maintain and, in theory, cheaper to run at scale.
That’s all pretty technical, but it’s an important reminder that not every part of AI development is moving at breakneck speeds. While model training races ahead, a lot of the technical infrastructure those models need is still subject to the slow log-rolling of standards-body consensus. It really is happening; it’s just a little slower!
