Anthropic 将 MCP 从会话式改为请求式协议

Some good development on the MCP side from Anthropic.

They are turning MCP from a session-heavy connection into a simpler request-based protocol that fits normal cloud infrastructure.

i.e. MCP’s official core now moves from ongoing stateful sessions (where MCP server had to remember an ongoing client session between requests) to independent request-and-response interactions. Means each request can be handled on its own by any server instance,

Previously, MCP servers were expected to maintain an ongoing connection with each client, which made them harder to scale, restart, or run across serverless and edge environments.

Now, each request can be handled independently, so any available server instance can process it without remembering the full interaction history.

Anthropic is also separating richer features, such as interactive interfaces and long-running tasks, into optional extensions instead of packing everything into the core protocol.

Will make MCP easier to deploy, scale, secure, and integrate into production applications.
