3. `get_current_time` - Current time with timezone
4. `get_date` - Current date information
5. `get_timezone_info` - Timezone info with DST
6. `convert_timezone` - Convert between timezones

**Server Status**: ✅ Running on http://localhost:8000

**Root Endpoint**: Returns enhanced JSON with:
- Server status and version

- ✅ MCP response → LLM format conversion
- ✅ Error handling
- ✅ Health check
- ✅ Test script

**Test Results**: ✅ All tests passing
- Tool discovery: 6 tools found
- Tool calling: echo, weather, get_current_time all working
- LLM format conversion: Working correctly
- Health check: Working

**To Test**:
```bash
cd mcp-adapter
pip install -r requirements.txt
python test_adapter.py
```

### ✅ TICKET-032: Time/Date Tools

## Next Steps

### Immediate

1. ✅ **MCP Server** - Complete and running with 6 tools
2. ✅ **MCP Adapter** - Complete and tested, all tests passing
3. ✅ **Time/Date Tools** - All 4 tools implemented and working

### Ready to Start

3. **Set Up LLM Servers** (if hardware ready)
   ```bash
   # 4080 Server
   cd llm-servers/4080
   ./setup.sh
   
   # 1050 Server
   cd llm-servers/1050
   ./setup.sh
   ```

### Short Term

4. **Integrate MCP Adapter with LLM**
   - Connect adapter to LLM servers
   - Test end-to-end tool calling

5. **Add More Tools**
   - Weather tool (real API)
   - Timers and reminders
   - Home tasks (Kanban)

## Testing Status

- ✅ MCP Server: Running and fully tested (6 tools)
- ✅ MCP Adapter: Complete and tested (all tests passing)
- ✅ Time Tools: All 4 tools implemented and working
- ✅ Root Endpoint: Enhanced JSON with tool information
- ⏳ LLM Servers: Setup scripts ready, pending server setup
- ⏳ Integration: Pending LLM servers

## Known Issues

- None currently - all implemented components are working correctly

## Dependencies
