Known Issues & Limitations

1. Prompts Deferred

Issue: FastMCP prompt API changed in v2.13.0 Status: Prompts commented out, tools fully functional Impact: Low - prompts are optional, tools work perfectly Resolution: Will add once API confirmed

2. Dependency Conflicts (Expected)

Issue: Some packages have version conflicts with Gradio Status: Warnings only, no functional impact Impact: None - Gradio being removed Resolution: Clean install recommended

3. Windows Path Issues

Issue: Windows pip sometimes has permission errors Status: Resolved using --user flag Impact: Installation only Resolution: Use pip install --user
