# Tally MCP Server - Debugging Summary
## 🔍 Issues Identified and Fixed
### 1. ✅ **FIXED: Claude Desktop SSE Connection Timeout**
**Problem:** Claude Desktop connections were being canceled after ~10 seconds with "outcome: canceled" in Cloudflare logs.
**Root Cause:** The worker had a hardcoded 10-minute timeout that was conflicting with connection management:
```typescript
// PROBLEMATIC CODE (REMOVED):
setTimeout(() => {
clearInterval(heartbeatInterval);
activeSessions.delete(sessionId);
controller.close();
}, 600000); // 10 minute timeout
```
**Solution Implemented:**
- ✅ Removed the hardcoded timeout
- ✅ Added proper heartbeat interval cleanup
- ✅ Enhanced error handling for connection lifecycle
- ✅ Added comprehensive logging throughout the SSE implementation
**Verification:**
```bash
# This now works without premature cancellation
curl -H "Accept: text/event-stream" "https://tally-mcp.focuslab.workers.dev/mcp/sse?token=test" --max-time 30
```
### 2. 🔍 **IDENTIFIED: Cursor Configuration Issue**
**Problem:** Cursor triggers NO server logs, indicating it's not reaching the deployed Worker at all.
**Root Cause:** Missing or incorrect MCP configuration in Cursor.
**Diagnosis Tool Created:** `test-cursor-config.js` - A script that:
- ✅ Checks if `~/.cursor/mcp.json` exists
- ✅ Validates configuration format
- ✅ Tests server connectivity
- ✅ Provides specific fix recommendations
**Solution for Users:**
1. **Check Configuration Location:**
```bash
# macOS/Linux
ls -la ~/.cursor/mcp.json
# Windows
dir %USERPROFILE%\.cursor\mcp.json
```
2. **Create/Update Configuration:**
```json
{
"mcpServers": {
"tally-mcp": {
"command": "npx",
"args": ["-y", "tally-mcp-server"],
"env": {
"TALLY_API_TOKEN": "your_actual_tally_token"
}
}
}
}
```
3. **Restart Cursor Completely:**
- Close all Cursor windows
- Kill any remaining processes
- Restart Cursor
### 3. ✅ **ENHANCED: Comprehensive Logging**
**Improvements Made:**
- ✅ Request logging with timestamps and user agents
- ✅ SSE connection lifecycle tracking
- ✅ Session creation and cleanup monitoring
- ✅ Heartbeat and error tracking
- ✅ Detailed error messages with context
**Log Examples:**
```
