🚀 Deployment Instructions for Hugging Face Spaces:

  1. Create a new Space on Hugging Face
  2. Set up your Hugging Face Inference Endpoint and get the endpoint URL
  3. Set your tokens in Space settings (use Secrets for security):
    • Go to Settings → Repository secrets
    • Add: HF_API_KEY = your_huggingface_api_key_here
    • Endpoint is now hardcoded to your specific Inference Endpoint
  4. Upload these files to your Space repository
  5. Install requirements: The Space will auto-install from requirements.txt

🔧 MCP Server Mode:

This app functions as both a web interface AND an MCP server for Claude Desktop and other MCP clients.

Available MCP Tools:

  • validate_rdf_tool: Validate RDF/XML against SHACL shapes
