Claude Code v2.1.128: MCP Tool Count Visibility, ZIP Plugin Archives, and Bug Fixes
Anthropic
Claude Code v2.1.128 (May 4) adds MCP server tool-count display in /mcp with flagging of servers reporting 0 tools; --plugin-dir now accepts .zip archives; --channels works with console (API key) auth; the /model picker collapses duplicate Opus 4.7 entries; subprocesses no longer inherit OTEL_* environment variables; workspace is now a reserved MCP server name; reconnecting MCP servers no longer flood conversation with full tool-name lists. Bug fixes include focus mode dimming, desktop notification glitch on /exit in Kitty, drag-and-drop image upload hangs, large-input crash (>10 MB via stdin), and parallel shell tool call failures.
Why it matters
MCP tool-count visibility and reconnection behavior improvements reduce operational friction for teams running multiple MCP servers in production. ZIP plugin archive support simplifies plugin distribution without requiring directory unpacking.
Importance: 2/5
