MCP — Support for the 2026-07-28 spec is rolling out across Claude. The protocol moves from bidirectional and stateful to request/response, so MCP servers can now live on serverless and edge infrastructureEXTENSIONS — Three official extensions have landed: MCP Apps for server-rendered UI, Tasks for async and long-running work, and Enterprise Managed Auth for IdP-based org-wide provisioningADOPTION — MCP passed 400 million monthly SDK downloads, roughly 4x growth this year, settling into its role as the standard way to connect agents to applicationsQUOTA — Today, August 19, is the last day of the 50 percent weekly usage boost for Claude Code subscribers. If you have long agent runs queued, this is the windowPRICING — Claude Sonnet 5's introductory rate of $2 per million input tokens and $10 output ends August 31; standard pricing of $3 and $15 takes over on September 1, twelve days outFIX — A bug where MCP v2 connections endlessly reopened subscriptions against servers with fixed timeouts is resolved, and a forward_user_identity setting was added for user attributionMCP — Support for the 2026-07-28 spec is rolling out across Claude.

When Claude API Streaming Stops Without an Error: Detecting Silent Stalls and Resuming Mid-Stream

How to catch the 'silent stall' where Claude API streaming stops with no exception at all, using a content-level watchdog that times the gap between tokens, plus a resume path that carries received text forward as an assistant prefill, and a four-layer timeout budget for long-running automation.
