### 🔧 **If You See Warnings**
**Don't worry!** The package is designed to work even with warnings:
#### ⚠️ "API key warning is normal"
- **What it means**: PERPLEXITY_API_KEY not set
- **Impact**: Analytics and models work, API calls need key
- **Fix**: `export PERPLEXITY_API_KEY="your-key"`
#### ⚠️ "Cache system has issues"
- **What it means**: Cache initialization failed
- **Impact**: Still works, just no caching
- **Fix**: Usually resolves on restart
#### ⚠️ "Directory write permissions limited"
- **What it means**: Can't write log files
- **Impact**: Logging goes to console only
- **Fix**: Run from writable directory
### 🚀 **Immediate Usage**
After installation, you can immediately:
```bash
# Test the installation
npm test
# Start the MCP server
nascoder-perplexity-mcp
# View available models
echo '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"perplexity_models","arguments":{}}}' | nascoder-perplexity-mcp
# Get analytics
