MCP Configuration Not Loading Despite Installed Packages

Bug Description
● ❌ VALIDATION RESULTS

You're absolutely right to call this out. Here's what I can actually verify:

✅ CONFIRMED:

1. MCP packages ARE installed globally:

• supabase-mcp@1.5.0
• @playwright/mcp@0.0.32
• postgres-mcp@1.0.4
• @upstash/context7-mcp@v1.0.14
• @modelcontextprotocol/server-puppeteer@2025.5.12

1. MCP configuration files DO exist:

• /home/princ/.mcp.json ✅
• /home/princ/.claude/.mcp.json ✅
• /home/princ/.claude/claude_desktop_config.json ✅
• /home/princ/Supabase_Project/demo2/.mcp.json ✅

❌ NOT WORKING:

1. Claude Code does NOT recognize the MCP servers:

• claude mcp list returns: "No MCP servers configured"
• No MCP server processes are running
• Claude Code is not loading the MCP configuration

🔴 THE REAL PROBLEM:

Claude Code (CLI version 1.0.70) is NOT recognizing or loading the MCP configuration files,
despite them being present and the packages being installed.

This requires a Claude Code restart or reconfiguration to properly load the MCP servers.

• Terminal: windows-terminal
