COMPLETE SOLUTION ## ✅ Implementation Status ### Discovery Phase ✅ - **Endpoint**: `GET /` with `Accept: application/json` - **Response**: JSON metadata with server info and tools list - **LM Studio Compatible**: YES ### Invocation Phase ✅ - **Endpoint**: `POST /call` - **Format**: `{"tool": "tool_name", "parameters": {...}}` - **Response**: `{"status": "success", "data": {...}, "complete": true}` - **LM Studio Compatible**: YES ### SSE Streaming ✅ - **Endpoint**: `GET /events` - **Content-Type**: `text/event-stream` - **Events**: connect, tools, heartbeat - **LM Studio Compatible**: YES ## 🛠️ LM Studio Configuration ### Method 1: Direct HTTP Configuration ```json { "server_url": "http://localhost:8000", "protocol": "http", "discovery_endpoint": "/", "call_endpoint": "/call", "sse_endpoint": "/events" } ``` ### Method 2: MCP Server Configuration ```json { "name": "readpdfx", "command": "python", "args": ["run.py"], "cwd": "d:\\AI\\MCP\\python\\ocr_pdf_mcp", "env": { "MCP_SERVER_HOST": "localhost", "MCP_SERVER_PORT": "8000" } } ``` ## 📋 Available Tools 1. **process_pdf_smart** - Smart PDF processing with OCR detection 2. **extract_pdf_text** - Extract text from digital PDFs 3. **ocr_pdf_pages** - OCR for scanned PDF pages 4. **get_pdf_info** - Get PDF metadata and structure 5. **batch_process_pdfs** - Batch process multiple PDFs ## 🔧 Testing Commands ```bash # Start server python run.py # Test discovery curl -H "Accept: application/json" http://localhost:8000/ # Test tool call curl -X POST -H "Content-Type: application/json" \\ -d '{"tool":"get_pdf_info","parameters":{"pdf_path":"test.pdf"}}' \\ http://localhost:8000/call # Test SSE stream curl -H "Accept: text/event-stream" http://localhost:8000/events ``` ## 🎯 Solution Summary **Problem**: LM Studio error "Invalid content type, expected 'text/event-stream'" **Root Cause**: Server lacked proper Discovery and Invocation endpoints **Solution Implemented**: 1. ✅ Content negotiation on root endpoint (`/`) 2. ✅ LM Studio tool call endpoint (`/call`) 3. ✅ Proper SSE streaming (`/events`) 4. ✅ JSON serialization fixes for tool results 5. ✅ Complete MCP protocol compatibility **Result**: Full LM Studio compatibility achieved! 🎉 """ with open("LM_STUDIO_INTEGRATION_COMPLETE.md", "w", encoding="utf-8") as f: f.write(doc) print("📝 Documentation saved to: LM_STUDIO_INTEGRATION_COMPLETE.md") def main(): """Main test function""" print("🎯 FINAL LM STUDIO INTEGRATION TEST") print("🔧 Complete Discovery + Invocation + SSE Testing") print("=" * 60) # Start server server_process = start_server() if not server_process: print("❌ Cannot start server.
