Key New Features in v2.1.186

Claude Code v2.1.186 introduces several practical improvements. The addition of MCP login/logout commands simplifies authentication in remote setups. The /workflows view now includes status filters for quick task monitoring. The /plugin Installed tab gains a Skills section for better organization of installed skills.

Streaming stability and background task improvements are also highlights. Reduced disconnections during long outputs and strengthened permission rules enhance overall safety. Building on v2.1.185’s wait message and retry improvements, this release focuses on reliability.

These changes deliver immediate value for daily Claude Code users. Check the official GitHub Releases page for full details.

Enhanced MCP (Model Context Protocol) Support

The MCP login/logout commands support the –no-browser option, enabling login and logout without a browser in SSH-only environments.

Usage is straightforward: simply run claude mcp login --no-browser. Security considerations around token handling are emphasized in the official Changelog, which also outlines future MCP expansion plans.

This feature is particularly useful for managing Claude Code sessions on remote servers, significantly improving workflow flexibility for developers.

Workflow and Plugin Management Improvements

The status filter in /workflows allows filtering tasks by state such as in-progress, completed, or errored. This boosts visibility when handling large numbers of workflows.

The new Skills section in the /plugin Installed tab makes it easier to view and manage installed skills. Existing users benefit from improved plugin organization and development efficiency.

These refinements address minor friction points in daily use of Claude Code.

Stability Enhancements and Other Changes

Streaming stabilization reduces disconnections and latency during long responses. Strengthened permission rules for background tasks provide better security, especially valuable for team environments.
