[BUG] Cloud MCP (RUBE/Composio) and Remote Control not loading in interactive sessions - Windows

Description

Cloud MCP integrations (specifically RUBE/Composio) and Remote Control are both not loading in interactive Claude Code sessions despite being connected/authorized on the claude.ai side.

Environment

• Claude Code version: 2.1.87
• OS: Windows 11 Pro for Workstations 10.0.26200
• Auth: OAuth token, firstParty provider
• Plan: Max (1M context, Opus)
• Shell: bash (Git Bash)

Current behavior

• claude mcp list shows only local MCP servers (mcp-obsidian, appfolio). RUBE cloud MCP does not appear at all.
• RUBE tools (mcp__claude_ai_Rube__*) are referenced in permissions config but never load into the session's available tool list.
• Remote Control setting (enableRemoteControlForAllSessions: true) is enabled but remote control is not available.
• Both features are missing across ALL directories, not just one project.

Steps to reproduce

1. Confirm RUBE is connected on claude.ai (shows as connected)
2. Disconnect and reconnect RUBE on claude.ai, reauthorize on Composio site
3. Launch claude in any directory
4. Run claude mcp list - RUBE not shown
5. Check /mcp dialog - RUBE not listed
6. Remote control also unavailable

Troubleshooting already attempted

• Restarted Claude Code 5+ times
• Tested in multiple directories (project dir and home dir)
• Disconnected and reconnected RUBE on claude.ai browser and desktop app
• Reauthorized on the RUBE/Composio site
• Verified auth status (claude auth status shows logged in, oauth_token, firstParty)
• Verified settings (enableRemoteControlForAllSessions: true in settings.json)
• No enterprise managed-mcp.json present

Expected behavior

RUBE cloud MCP should appear in claude mcp list and its tools should be available in interactive sessions. Remote Control should be accessible.
