# COMPREHENSIVE GHIDRA MCP DATA STRUCTURE IMPLEMENTATION SUMMARY

## 🎯 Implementation Overview

Successfully implemented **ALL** missing data structure management functionality for Ghidra MCP, extending from basic structure operations to advanced category management and function signatures. This represents a complete solution for comprehensive data structure management within Ghidra through MCP tools.

## ✅ COMPLETED IMPLEMENTATIONS

### HIGH PRIORITY FEATURES (100% Complete)

#### 1. Structure Modification Operations
- **✅ Field Addition**: `add_struct_field` - Add new fields to existing structures
- **✅ Field Removal**: `remove_struct_field` - Remove fields from structures
- **✅ Field Modification**: `modify_struct_field` - Change field types and properties
- **✅ Structure Deletion**: `delete_data_type` - Remove entire data structures

#### 2. Advanced Type Creation
- **✅ Array Types**: `create_array_type` - Create arrays of any base type with specified size
- **✅ Pointer Types**: `create_pointer_type` - Create pointer types to any base type
- **✅ Structure Layout**: `get_struct_layout` - Detailed structure inspection with offsets

### MEDIUM PRIORITY FEATURES (100% Complete)

#### 3. Category Management System
- **✅ Category Creation**: `create_data_type_category` - Create new data type categories
- **✅ Type Organization**: `move_data_type_to_category` - Move types between categories
- **✅ Category Listing**: `list_data_type_categories` - List all available categories

#### 4. Advanced Function Types
- **✅ Function Signatures**: `create_function_signature` - Create function pointer types
- **✅ Parameter Support**: Full parameter definition with names and types
