# OpenProject MCP Server - Rebuild Summary
## ✅ Successfully Implemented Work Package Relations Feature
### 🔧 **What Was Built**
1. **Enhanced OpenProject Client** (`src/openproject_client.py`)
- ✅ Fixed `create_work_package_relation()` to match OpenProject API v3 spec
- ✅ Added `get_work_package_relations()` for retrieving relations
- ✅ Added `delete_work_package_relation()` for removing relations
- ✅ Full API compliance with proper authentication and error handling
2. **Updated Data Models** (`src/models.py`)
- ✅ Enhanced `WorkPackageRelation` with complete field set
- ✅ Updated `WorkPackageRelationCreateRequest` with validation
- ✅ Support for all relation types: follows, precedes, blocks, blocked, relates, duplicates, duplicated
3. **Enhanced MCP Server Tools**
- ✅ Improved `create_work_package_dependency` with description and lag support
- ✅ Added `get_work_package_relations` tool
- ✅ Added `delete_work_package_relation` tool
- ✅ Added resource endpoint: `openproject://work-package-relations/{id}`
4. **Python 3.9 Compatibility** (`src/mcp_server_compatible.py`)
- ✅ Created compatible version that works without FastMCP
- ✅ All relation tools implemented and tested
- ✅ Proper MCP protocol handling for stdin/stdout communication
### 🧪 **Testing & Validation**
- ✅ **Comprehensive test suite** (`test_relations.py`) - Full API testing
- ✅ **Compatibility testing** (`test_server_compatible.py`) - Python 3.9 validation
- ✅ **Import validation** - All modules load correctly
- ✅ **Tool signature verification** - All parameters match specification
- ✅ **Error handling** - Comprehensive validation and error messages
### 📚 **Documentation**
- ✅ **Complete Relations Guide** (`RELATIONS_GUIDE.md`) - Comprehensive usage documentation
- ✅ **Updated README** - Added new tools and resources
- ✅ **API Compliance Details** - Exact OpenProject API v3 specification adherence
## 🚀 **How to Use the Rebuilt Server**
### **For Python 3.10+ (FastMCP)**
```bash
python3 scripts/run_server.py
```
### **For Python 3.9 (Compatible Version)**
```bash
python3 scripts/run_server_compatible.py
```
### **Test the Implementation**
```bash
# Test compatibility and tool signatures
python3 test_server_compatible.py
# Test full functionality (requires OpenProject connection)
python3 test_relations.py
```
## 🎯 **New Relations Capabilities**
### **1. Create Relations with Advanced Parameters**
```python
await create_work_package_dependency(
from_work_package_id=456, # Dependent task
to_work_package_id=123, # Prerequisite task
relation_type="follows", # Relation type
description="Dev follows design approval", # Description
lag=2 # 2 working days lag
)
```
### **2. Retrieve Work Package Relations**
```python
relations = await get_work_package_relations(work_package_id=123)
```
### **3. Delete Relations**
```python
await delete_work_package_relation(relation_id=789)
```
### **4. All Supported Relation Types**
- **follows** - Chronological dependency (WP A follows WP B)
- **precedes** - Reverse of follows (automatically set by OpenProject)
- **blocks** - Blocking relationship
- **blocked** - Reverse of blocks
- **relates** - General relationship without dependency
- **duplicates/duplicated** - Duplication relationships
## 🔧 **Configuration**
### **Environment Setup**
1. Copy `env.example` to `.env`
2. Configure your OpenProject URL and API key:
```env
OPENPROJECT_URL=http://your-openproject-instance:3000
OPENPROJECT_API_KEY=your_40_character_api_key_here
```
### **AI Assistant Integration (Claude)**
```json
{
"mcpServers": {
"openproject": {
"command": "python3",
"args": ["/full/path/to/openproject-mcp-server/scripts/run_server_compatible.py"],
"env": {
"OPENPROJECT_URL": "http://localhost:3000",
"OPENPROJECT_API_KEY": "your_api_key_here"
}
}
}
}
```
