Anthropic makes MCP stateless to simplify scaling remote agent servers
rohanpaul_ai · x · 2026-07-29
Anthropic is moving MCP from a stateful session model to stateless request/response interactions.
- The new core makes each request independently runnable by any server instance, which should improve scaling, restarts, and deployment on serverless or edge infrastructure.
- Richer capabilities such as interactive UIs and long-running tasks are being split into optional standardized extensions, including MCP Apps and Tasks.
- The post frames this as one of the protocol’s most significant releases, with MCP recently surpassing 400M monthly SDK downloads and becoming a de facto standard for connecting agents to apps.
