# Diagnostic: Why MCP Tools Aren't Showing
## Current Situation
- ✅ Configuration file is valid JSON (no BOM)
- ✅ Server can start successfully
- ✅ Database connection works
- ❌ Claude Desktop is NOT starting the MCP server
- ❌ No MCP logs exist
- ❌ No tools visible in Claude
## Possible Issues
### Issue 1: Claude Desktop Version
Your version is **1.0.1768**. MCP support might not be fully available in this version.
**Solution:** Update Claude Desktop to the latest version.
### Issue 2: MCP Support Not Enabled
MCP servers might need to be enabled in Claude Desktop settings.
**Check:** Look in Claude Desktop settings/preferences for "MCP" or "Model Context Protocol" options.
### Issue 3: Configuration Format
The format might need adjustment.
**Current format:**
```json
{
"mcpServers": {
"inventory-mcp": {
"command": "C:\\Users\\aditi\\Anaconda3\\python.exe",
"args": ["C:\\Users\\aditi\\Downloads\\inventory-mcp-server-master\\inventory-mcp-server.py"],
"env": {
"SUPABASE_DB_PASSWORD": "root"
}
}
}
}
```
## What to Check
1. **Update Claude Desktop** - Get the latest version
2. **Check Settings** - Look for MCP/server settings
3. **Check for Hammer Icon** - Bottom-left of input box
4. **Ask Claude Directly** - Try "List all inventory items"
## Alternative: Use Claude API Instead
If Claude Desktop doesn't support MCP servers yet, we could create a Claude API integration instead.
