Anthropic’s MCP overhaul goes stateless as monthly SDK downloads top 400 million
新智元 · wechat · 2026-07-29
Anthropic’s MCP protocol gets its biggest update yet, with a push toward a stateless request/response design, standardized extensions, and stronger enterprise auth.
- Stateless by default: the protocol moves away from session-heavy stateful connections, making it easier to run MCP servers on serverless and edge platforms, and to scale behind ordinary load balancers.
- New extension primitives: the update adds first-class support for interactive UI rendering inside Claude, async task handling, and a more explicit way to pass handles when state must persist across calls.
- Enterprise and security upgrades: Anthropic says the revision tightens OAuth/OIDC alignment, adds stronger issuer validation, and improves enterprise-managed access for IdP-based deployments.
- Ecosystem impact: the article says monthly SDK downloads have surpassed 400 million, with TypeScript and Python SDK totals each above 1 billion, and that Claude’s app ecosystem now includes 950+ MCP servers.
