# UV Setup Complete ✅
The BLS MCP server is now fully configured to work with `uv`!
## What Was Done
### 1. UV Initialization ✅
- Ran `uv sync` to create `.venv` and install dependencies
- Generated `uv.lock` file for reproducible environments
- Verified all 27 packages installed successfully
### 2. Convenience Scripts Created ✅
Three new shell scripts for common operations:
**`scripts/uv_start_server.sh`**
- Starts the MCP server using uv
- Usage: `./scripts/uv_start_server.sh`
**`scripts/uv_test_client.sh`**
- Tests the MCP server with sample requests
- Usage: `./scripts/uv_test_client.sh`
**`scripts/uv_test.sh`**
- Runs the pytest test suite with uv
- Usage: `./scripts/uv_test.sh`
- Supports pytest arguments: `./scripts/uv_test.sh -v`
### 3. Documentation Created ✅
**`docs/UV_USAGE.md`**
- Comprehensive UV usage guide
- Command reference
- Integration examples
- Troubleshooting tips
- Performance comparisons
### 4. README Updated ✅
- Added UV as the recommended installation method
- Included quick start with UV
- Kept traditional pip method as alternative
### 5. Testing ✅
- Successfully ran MCP server with UV
- All 5 test requests passed
- Server logs confirmed proper operation
## How to Use
### Quick Commands
```bash
# First time setup
cd bls_mcp
uv sync
# Start server
./scripts/uv_start_server.sh
# Test server
./scripts/uv_test_client.sh
# Run tests
./scripts/uv_test.sh
```
### Direct UV Commands
```bash
# Run server
uv run python scripts/start_server.py
# Run tests
uv run pytest tests/ -v
# Add dependency
uv add requests
# Update dependencies
uv sync --upgrade
```
## Speed Comparison
### Installation Time
| Method | Time |
|--------|------|
| **uv** | **~3 seconds** ⚡ |
| pip | ~30 seconds |
### Server Startup
| Method | Time |
|--------|------|
| Both | ~0.5 seconds (same - startup speed is identical) |
The speed advantage is in **dependency installation and management**, not runtime.

## Integration with Claude Desktop
### Using UV Script
Edit `~/Library/Application Support/Claude/claude_desktop_config.json`:
```json
{
"mcpServers": {
"bls-data": {
"command": "/Users/YOUR_USERNAME/Downloads/projects/bls_food/bls_mcp/scripts/uv_start_server.sh"
}
}
}
```
**Note**: Replace `YOUR_USERNAME` with your actual username.
### Using UV Directly
```json
{
"mcpServers": {
"bls-data": {
"command": "uv",
"args": [
"run",
"--project",
"/Users/YOUR_USERNAME/Downloads/projects/bls_food/bls_mcp",
"python",
"scripts/start_server.py"
]
}
}
}
```

## Why UV?
### Benefits
1. **Speed**: 10-100x faster dependency resolution
2. **Reliability**: Better conflict resolution
3. **Reproducibility**: Lock files ensure consistency
4. **Simplicity**: No need to activate virtualenv
5. **Modern**: Rust-based, actively maintained
### When to Use
- ✅ Development (highly recommended)
- ✅ CI/CD pipelines (faster builds)
- ✅ Team projects (reproducible envs)
- ✅ Large projects (faster resolution)
### When pip Might Be Better
- Simple, single-file scripts
- Legacy systems where uv can't be installed
- When you already have a working pip setup
## Migrating from pip to uv
If you were using pip:
```bash
# Old way
python -m venv venv
source venv/bin/activate
pip install -e .
# New way (simpler!)
uv sync
```
All your existing scripts work the same:
```bash
# These still work
uv run python scripts/start_server.py
uv run pytest tests/
```
## Common Questions
### Q: Do I need to activate the virtualenv?
**A**: No! `uv run` handles it automatically.
### Q: Where is the virtual environment?
**A**: In `.venv/` (created automatically by uv)
### Q: Can I still use pip?
**A**: Yes, but uv is recommended for consistency.
### Q: What if I don't have uv installed?
**A**: Install it with: `curl -LsSf https://astral.sh/uv/install.sh | sh`
### Q: Does this work on Windows?
**A**: Yes! Use the Python commands directly:
```bash
uv run python scripts/start_server.py
```
## Troubleshooting
### Issue: `uv: command not found`
```bash
# Install uv
curl -LsSf https://astral.sh/uv/install.sh | sh
# Add to PATH
export PATH="$HOME/.local/bin:$PATH"
```
### Issue: Dependencies not syncing
```bash
# Remove lock and re-sync
rm uv.lock
uv sync
```
### Issue: Script permission denied
```bash
# Make executable
chmod +x scripts/uv_*.sh
```
## Next Steps
1. ✅ UV is configured and working
2. ✅ Convenience scripts are ready
3. ✅ Documentation is complete
4. Ready for Phase 2 (ngrok + SSE transport)
