Claude Code v2.1.186: MCP CLI Auth, Bash Auto-Response, Workflow Filtering
Anthropic
Claude Code v2.1.186 (released June 22) adds `claude mcp login <name>` and `claude mcp logout <name>` CLI commands for authenticating MCP servers without the interactive menu, makes `!` bash commands trigger automatic Claude responses (configurable via `respondToBashCommands: false`), adds status filtering to the `/workflows` agent detail view and a Skills section to `/plugin`, and fixes streaming failures after machine sleep plus numerous subagent and session-management bugs.
Why it matters
The new MCP CLI auth flow and bash auto-response significantly smooth headless and SSH workflows, while the workflow/plugin UX additions reflect Claude Code's growing role as an orchestrator of multi-agent, multi-tool pipelines.
