# 🎯 LM Studio MCP Integration - 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! 🎉
