# BlenderMCP v1.3.0 - Development Status
## Status: DEVELOPMENT - TESTING PHASE
BlenderMCP has completed a significant development milestone with the implementation of comprehensive retopology tools and modular architecture refactoring. However, the project is currently in the **testing and verification phase** and is not yet ready for production deployment.
## What's Been Accomplished
### Retopology Tools (11 tools implemented)
**Mesh Analysis:**
- `mesh_stats` - Detailed topology statistics
- `detect_topology_issues` - Problem detection
**Remeshing Operations:**
- `voxel_remesh` - Voxel-based remeshing
- `quadriflow_remesh` - Quad-dominant topology
- `decimate` - Polygon reduction
- `shrinkwrap_reproject` - Surface projection
**Viewport & Shading:**
- `set_view_projection` - Ortho/Perspective toggle
- `align_view_to_axis` - Axis alignment
- `frame_selected` - Frame objects in viewport
- `mark_seams_by_angle` - UV seams marking
- `mark_sharp_by_angle` - Sharp edges marking
**Guided Workflows:**
- `retopo_pipeline` prompt - Step-by-step retopology guidance
### Architecture Improvements
- Modular structure with separation of concerns
- server.py reduced from 1514 to 1273 lines (clean wrappers only)
- 8 tool modules + 2 prompt modules + integrations organized
- Clean architecture for future expansion
### Documentation (8 files)
- **START_HERE.md** - Quick start (3 steps)
- **QUICKSTART.md** - Full setup instructions
- **ARCHITECTURE.md** - Architecture documentation (updated)
- **REFACTORING_SUMMARY.md** - Refactoring overview
- **RETOPO_IMPLEMENTATION.md** - Implementation details
- **FINAL_REPORT.md** - Project report
- **README.md** - User guide + workflows
- **15 BDD feature files** - Gherkin specifications
## Known Issues and Blockers
### Previously Resolved Issues
**CRITICAL #1: Package Import Failure** - RESOLVED
- Issue: Package configuration mismatch between pyproject.toml and directory structure
- Status: FIXED - pyproject.toml correctly configured with `package-dir = {"blender_mcp" = "src"}`
**CRITICAL #2: Duplicate Remeshing Implementations** - RESOLVED
- Issue: Duplicate implementations in `tools/remeshing.py` vs `retopo_tools/remesh.py`
- Status: FIXED - Consolidated to `retopo_tools/remesh.py`, removed duplicates
**CRITICAL #3: Undocumented Module Structure** - RESOLVED
- Issue: `retopo_tools/` directory not documented in ARCHITECTURE.md
- Status: FIXED - ARCHITECTURE.md updated to document both `tools/` and `retopo_tools/` modules
### Remaining Issues
**MAJOR #1: Version Inconsistencies** - NOW RESOLVED
- Issue: Different version numbers across files
- Status: FIXED - All files now reference version 1.3.0
**MAJOR #2: Limited Test Verification**
- Issue: Test suite exists but verification coverage is incomplete
- Impact: Need comprehensive end-to-end testing with actual Blender instances
- Tests exist with XFAIL markers (expected to fail during development)
- Effort Required: 2-3 weeks of comprehensive testing
**MINOR #1: Shared API Key**
- Issue: Hardcoded `RODIN_FREE_TRIAL_KEY` in addon.py:31
- Impact: Shared trial key with daily limits
- Recommendation: Users should obtain their own keys for production use
- Status: DOCUMENTED in README.md
## Testing Status
### Import Verification
Basic import testing has been performed:
- Module structure validated
- Import paths verified
- Tool registration confirmed
### Integration Testing
**Status:** Needs comprehensive testing
- End-to-end workflows need verification with live Blender instances
- MCP protocol communication needs stress testing
- Retopology operations need validation across different mesh types
### Test Coverage
**Current:** Import and basic functionality tests exist
**Needed:** Comprehensive integration tests with Blender
## Quick Start (For Testing/Development)
### Prerequisites
- Python 3.10+
- Blender 3.0+
- uv package manager
- Claude Desktop or Cursor
### Setup Steps
1. **Install Blender Addon:**
```
Edit → Preferences → Add-ons
Install... → select addon.py
Enable "Interface: Blender MCP"
In sidebar (N) → BlenderMCP → "Connect to Claude"
```
2. **Configure Claude Desktop:**
Add to `claude_desktop_config.json`:
```json
{
"mcpServers": {
"blender": {
"command": "uvx",
"args": ["blender-mcp"]
}
}
}
```
3. **Test Connection:**
Ask Claude: "List all available Blender MCP tools"
You should see approximately 24 tools.

- Always save your work before running code execution commands
### Performance
- Lazy loading of modules
- Connection pooling implemented
- Minimal overhead in wrapper functions
- QuadriFlow may be slow on large meshes (expected behavior)
### Compatibility
