Anthropic Upgrades Claude Code With MCP Tool Search

Anthropic recently rolled out several updates to Claude Code and Cowork, including MCP Tool Search, Cowork availability for Pro subscribers, and UI and connector improvements. The Tool Search lazy-loads MCP tools when their descriptions would exceed 10% of the context window, reducing token usage and enabling support for 50+ tools without preloading. These changes accelerate developer workflows and multi-agent orchestration.
