Claude.ai MCP connectors feature flag disabled after update

Description

After updating Claude Code, I lost access to the Claude.ai MCP connectors feature. The feature flag tengu_claudeai_mcp_connectors is set to false in cachedGrowthBookFeatures, and the mcpServers config is empty.

Environment

• Claude Code version: 2.1.38
• Install method: native
• Platform: Linux (Ubuntu, 6.11.0-29-generic)
• Auto-updates: disabled
• Subscription: Max plan
• Note: Running on a remote server (SSH), not the machine where Claude Code Desktop is installed

Debug Output

2026-02-10T06:15:46.629Z [DEBUG] [claudeai-mcp] Checking gate (cached)...
2026-02-10T06:15:46.629Z [DEBUG] [claudeai-mcp] Gate returned: false
2026-02-10T06:15:46.629Z [DEBUG] [claudeai-mcp] Disabled via gate

Steps to Reproduce

1. Previously had access to Claude.ai MCP connectors
2. Updated Claude Code to 2.1.38
3. Claude.ai MCP connectors no longer available
4. Debug logs confirm the feature is gated off server-side

Observed Behavior

• tengu_claudeai_mcp_connectors is false in cachedGrowthBookFeatures
• mcpServers at global level is empty {}
• All project-level mcpServers are also empty
• Feature is explicitly disabled via gate check

Expected Behavior

Claude.ai MCP connectors should remain accessible after updates, especially I previously had access.
