+
+## 🔍 API Patterns Identified
+
+### Standard Query Parameters
+All list endpoints support these parameters:
+- `limit`: Number of records to return (default: 100)
+- `sortfield`: Field to sort by
+- `sortorder`: ASC or DESC
+- `sqlfilters`: Advanced filtering using SQL-like syntax
+
+### Authentication
+- **Header:** `DOLAPIKEY: your_api_key`
+- **Format:** Token-based authentication
+- **Permission:** Tied to user permissions in Dolibarr
+
+### Response Structure
+- **Success:** Array of objects or single object
+- **Error:** JSON with error details
+- **HTTP Status Codes:** 200, 201, 400, 401, 403, 404, 500
+
+### Data Structure Pattern
+All business objects share common fields:
+- `id`: Unique identifier
+- `ref`: Reference number
+- `status`/`statut`: Status code
+- `date_creation`: Creation timestamp
+- `user_creation_id`: Creator user ID
+- `note_public`/`note_private`: Notes
+- `array_options`: Custom fields

+## 🔬 Testing Methodology Used
+
+1. **Connection Test:** Verified API accessibility with `/status` endpoint
+2. **Core Business Objects:** Tested major CRUD endpoints
+3. **Parameter Testing:** Verified filtering and pagination
+4. **Error Handling:** Documented error responses
+5. **Data Structure Analysis:** Analyzed response formats
+
+## 📝 Next Steps for MCP Development
+
+1. **Create Base MCP Server Structure**
+   - Follow prestashop-mcp reference pattern
+   - Implement dolibarr_client.py with all discovered endpoints
+   - Create MCP server with proper tool definitions
+
+2. **Implement Core Functions**
+   - Start with working endpoints (users, thirdparties, products, invoices, orders)
+   - Add comprehensive error handling
+   - Include proper parameter validation
+
+3. **Test and Expand**
+   - Test all CRUD operations
+   - Discover additional endpoints through testing
+   - Add advanced features (filtering, pagination, etc.)
+
+4. **Documentation and Deployment**
+   - Create comprehensive README
+   - Add Docker containerization
+   - Implement proper logging and monitoring
+
+## 🎯 Immediate Development Priority
+
+**High Priority Endpoints (Confirmed Working):**
+1. Users management
+2. Customer/Third party management  
+3. Product management
+4. Invoice management
+5. Order management
+
+**Medium Priority (Need Parameter Research):**
+1. Document management
+2. Contact management
+3. Project management
+
+**Low Priority (Discovery Required):**
+1. Setup/configuration endpoints
+2. Advanced modules (MRP, BOM, etc.)
+3. Integration-specific endpoints
