## Before Publishing

### Local Testing

1. **Test Python package locally:**
```bash
# Already done - entry point works!
uv pip install -e .
export CASTAI_API_KEY="test-key"
.venv/bin/castai-mcp-server
```

2. **Test npm wrapper locally:**
```bash
# Test the wrapper
node bin/castai-mcp-server.js
```

3. **Test with Claude Desktop:**
```json
{
  "mcpServers": {
    "castai-dev": {
      "command": "node",
      "args": [
        "/Users/narunaskapocius/repos/github/castai-mcp-external/bin/castai-mcp-server.js"
      ],
      "env": {
        "CASTAI_API_KEY": "your-real-api-key"
      }
    }
  }
}
```

## Publishing Checklist

When ready to publish:

- [ ] Get PyPI account and API token
- [ ] Get npm account and login
- [ ] Review PUBLISHING.md guide
- [ ] Build Python package: `uv build`
- [ ] Publish to PyPI: `uv publish`
- [ ] Wait 5-10 minutes for PyPI indexing
- [ ] Publish to npm: `npm publish`
- [ ] Test both installations
- [ ] Create GitHub release with tag v0.1.0

## After Publishing

Users will be able to install with:

```json
{
  "mcpServers": {

```

## Files Ready for Publishing

### PyPI Package
```
dist/

## Next Steps

1. **Test with real API key** (if not done already)
2. **Review PUBLISHING.md** for detailed publishing steps
3. **Publish to PyPI first** (npm wrapper depends on it)
4. **Publish to npm second**
5. **Test end-to-end** with `npx castai-mcp-server@latest`
