PPT-MCP has 22 tools with complete input schemas and descriptions, but quality is inconsistent. Naming follows verb_noun convention well (update_chart_data, add_connector, get_slide_info). However, descriptions are often generic (e.g., 'Add a new slide to the presentation') without explaining WHEN to use each tool or what distinguishes it from similar tools. Parameters lack constraints: connector_type accepts free-form strings instead of enums; RGB colors lack validation hints; numeric coordinates have no range documentation. Output schemas are not documented, callers cannot predict response structure. Error handling returns bare error strings without recovery guidance. No tool declares permissions or security implications. Overall, the server is functional but falls short of production-grade quality.

• Convert free-form string parameters to enums: connector_type → {straight, elbow, curved}; operation → {add, remove, list, update}; shape_type → {rectangle, circle, triangle, ...}; color_scheme → {professional_blue, corporate_gray, ...}.
• Document output schemas for all tools. Example: 'Returns {message: string, slide_index: int, shape_index: int}' or 'Returns {error: string, suggestion: string}' for failures.
• Enhance error messages with recovery guidance. Instead of 'Presentation not found', return 'Presentation not found. Call create_presentation() to create a new one, or open_presentation(file_path) to load an existing file.'
• Add range constraints to numeric parameters in descriptions. E.g., 'line_width: Width in points (0.5 - 10)'; 'font_size: Font size in points (8 - 72)'; 'start_x: X coordinate in inches (0 - 10)'.
• Split apply_professional_design into separate tools: apply_professional_theme, apply_slide_enhancement, get_available_color_schemes. Each tool should have one clear responsibility.
