This MCP server is completely independent. It only needs `requests`, `mcp`, and standard Python libraries. Just run: +```bash +pip install -r requirements.txt +``` + +### Q: Can I use this with multiple AI assistants? +**A:** Yes! You can configure it in both Cursor and Claude Desktop (or any MCP-compatible client). Just add the configuration to each one. + +### Q: Where do I get my API credentials? +**A:** Log into your Labellerr account at [https://pro.labellerr.com](https://pro.labellerr.com) and navigate to your account settings or API section to generate credentials. + +### Q: Does this work on Windows? +**A:** Yes! Just use Windows paths in your configuration: +```json +"args": ["C:\\path\\to\\SDKPython\\labellerr\\mcp_server\\server.py"] +``` +And the config file location is `%APPDATA%\Cursor\mcp.json` + +### Q: Can I use this server from regular Python code (not just AI assistants)? +**A:** Yes! You can import and use `api_client.py` directly: +```python +from labellerr.mcp_server.api_client import LabellerrAPIClient +client = LabellerrAPIClient(api_key="...", api_secret="...", client_id="...") +projects = client.list_projects() +``` + +### Q: What happens if my API credentials change? +**A:** Update your AI assistant's MCP configuration file with new credentials and restart the assistant. + +### Q: Can I limit which tools are available? +**A:** Currently, all 22 tools are exposed. If you need custom filtering, you can modify `tools.py` to remove unwanted tools from `ALL_TOOLS`. + +### Q: Is my data secure? +**A:** Yes! All communication uses HTTPS. Your credentials are stored locally in your MCP config. The server only runs locally on your machine and communicates directly with Labellerr's API. + +### Q: How do I update to the latest version? +**A:** Pull the latest code from the repository and reinstall dependencies: +```bash +git pull +pip install -r requirements.txt +``` +Then restart your AI assistant. -### Tools return errors -- Verify Labellerr API credentials are correct -- Check network connectivity -- Review operation history for error details +### Q: Can I run this on a remote server? +**A:** The current implementation uses STDIO (standard input/output) for communication, which requires local execution. For remote deployment, you'd need to modify it to use HTTP transport instead. -### AI assistant can't find tools -- Verify configuration file path is correct -- Use absolute paths, not relative paths -- Restart the AI assistant completely after configuration -- Check that credentials are set in the config file +### Q: What annotation types are supported? +**A:** All Labellerr annotation types: +- Bounding Box +- Polygon +- Dot/Point +- Classification (radio, checkbox, dropdown) +- Text input +- Audio annotation +- Video frame annotation -### Import errors -- Make sure you're in the correct directory -- Verify the Labellerr SDK is properly installed -- Check Python path: `python -c "import sys; print(sys.path)"` +### Q: How do I report bugs or request features? +**A:** Open an issue in the repository or contact Labellerr support at support@labellerr.com ## Development +### Three-Step Architecture + +The MCP server follows the SDK's three-step workflow for project creation: +1. **Dataset Creation**: Upload files, create dataset, poll status until ready +2. **Template Creation**: Define annotation questions and create template +3. **Project Creation**: Link dataset and template with rotation config + +This architecture ensures datasets are fully processed before being used in projects. + ### Adding New Tools -1.

api_client.py with SDK core module BREAKING CHANGE: Removed labellerr/mcp_server/api_client.py - Removed standalone api_client.py (761 lines of duplicated code) - Refactored server.py to use SDK core module: - LabellerrClient instead of LabellerrAPIClient - core.datasets functions for dataset operations - core.projects functions for project operations - core.annotation_templates for template creation - LabellerrProject methods for exports - Updated all handler methods to use SDK core functions - Updated test files to use SDK core imports - Tests now use LabellerrClient directly Benefits: - No code duplication between MCP server and SDK - Single source of truth for API operations - Automatic benefit from SDK improvements - Better maintained codebase ---
