The open loop now loads the MCP servers Claude Code would load in the same directory (user scope, the project's entries, the nearest .mcp.json), over streamable HTTP or stdio, and offers their tools as mcp__server__tool beside the workspace tools. Calls go through the approval drawer. Servers that are down are skipped. Images in results are named, not sent. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
