šÆ LM Studio SSE Fix - Final Solution
Masalah: LM Studio mendapat error "Invalid content type, expected 'text/event-stream'"
Solusi: Endpoint /events dengan format yang kompatibel dengan LM Studio
Status Error Sebelumnya:
- LM studio Log: 2025-11-03 01:17:50
- SSE content-type error meskipun sudah diimplementasi
Fix yang Diterapkan:
1. ā
Endpoint /events ditambahkan ke mcp_server_runner.py
2. ā
Content-type: text/event-stream dengan headers CORS
3. ā
Format event yang kompatibel dengan LM Studio:
- event: connect (connection established)
- event: tools (tools list)
- event: heartbeat (keep-alive)
Cara Test:
1. Start server: python run.py
2. Test endpoint: python test_events_simple.py
3. Konfigurasi LM Studio dengan endpoint: http://localhost:8000/events
Konfigurasi LM Studio:
- URL: http://localhost:8000
- SSE Endpoint: http://localhost:8000/events
- Protocol: HTTP dengan SSE
- Content-Type akan otomatis: text/event-stream
Endpoints yang tersedia untuk LM Studio:
- GET /events - SSE streaming (LM Studio compatible)
- GET /stream - Alternative streaming
- GET /sse/tools - Original SSE tools
- POST /jsonrpc - JSON-RPC 2.0
- GET /health - Health check
