# Smithery Timeout Resolution Strategy
## Problem Analysis
Smithery is experiencing a timeout during tool scanning with the error:
```
Failed to scan tools list from server: McpError: MCP error -32001: Request timed out
```
## Root Cause
The server is registering too many tools (25+ tools across 6 categories) during initialization, causing Smithery's tool scanning to timeout before completion.
## Solution Strategy: Progressive Loading
### Phase 1: Minimal Deployment (Current)
- **File**: `src/minimal-index.ts`
- **Tools**: 1 essential tool (`homeassistant_ping`)
- **Purpose**: Verify Smithery integration works
- **Expected Result**: Successful deployment and tool scanning
### Phase 2: Gradual Expansion
- **File**: `src/index.ts` with lazy loading
- **Tools**: 3 basic tools initially, then progressive loading
- **Strategy**:
1. Register minimal tools immediately
2. Load additional tools after 1-second delay
3. Monitor for timeout issues
### Phase 3: Full Feature Set
- **Tools**: All 25+ tools across 6 categories
- **Strategy**: Implement proper lazy loading per Smithery guidelines
## Implementation Files
### Current Testing Setup
```json
// package.json
"module": "src/minimal-index.ts" // For Phase 1 testing
```
### Production Setup
```json
// package.json
"module": "src/index.ts" // For Phase 2/3
```
## Tool Loading Strategies
### Strategy A: Ultra-Minimal (Phase 1)
```typescript
// Only 1 tool for testing
server.tool("homeassistant_ping", ...)
```
### Strategy B: Progressive Loading (Phase 2)
```typescript
// 3 tools immediately
registerMinimalTools(server);
// Remaining tools after delay
setTimeout(() => {
registerAllOtherTools(server);
}, 1000);
```
### Strategy C: Full Lazy Loading (Phase 3)
```typescript
// Implement proper MCP lazy loading
// Register tools only when first accessed
```
## Testing Process
1. **Deploy Phase 1** (minimal-index.ts)
- Verify no timeout errors
- Confirm tool scanning works
- Test basic connectivity
2. **Switch to Phase 2** (index.ts with delays)
- Monitor for timeout issues
- Adjust delay timings if needed
- Verify progressive loading works
3. **Optimize to Phase 3** (full implementation)
- Implement proper lazy loading
- Test all 25+ tools
- Performance optimization
## Rollback Plan
If any phase fails:
1. Revert package.json to previous working version
2. Redeploy with working configuration
3. Analyze logs and adjust strategy
## Success Metrics
- ✅ No timeout errors during deployment
- ✅ Tool scanning completes successfully
- ✅ All tools become available within 2 seconds
- ✅ Configuration UI displays correctly in Smithery
- ✅ Client connections work properly
## Current Status
- **Phase 1**: Ready for testing (minimal-index.ts)
- **Phase 2**: Implemented with delays (index.ts)
- **Phase 3**: Planned for future optimization
## Next Steps
1. Test Phase 1 deployment
2. Monitor Smithery scanning results
3. Switch to Phase 2 if Phase 1 succeeds
4. Document final working configuration
