Ghidra MCP Skill

This skill enables reverse engineering workflows using Ghidra through the Model Context Protocol (MCP).

Quick Start

1. •List available programs: list_programs to see what's loaded
2. •Read functions: read_functions with filtering to find targets
3. •Decompile: decompile_code to see source-like output
4. •Analyze references: find_references to trace data/code flow

Core Workflows

Analyzing a New Binary

1. •Use list_programs to confirm the binary is loaded
2. •Use read_functions to get an overview of functions
3. •Use decompile_code on interesting functions (like main or entry points)
4. •Use find_references to understand how functions/data are used
5. •Use manage_symbols to rename functions and variables as you understand them

Understanding a Function

1. •read_functions with name or address to get function metadata
2. •decompile_code with operation: decompile to see decompiled C code
3. •manage_functions with operation: get_variables to see local variables
4. •manage_functions with operation: get_graph to see control flow
5. •find_references with direction: to to find callers

Defining Data Structures

1. •read_data_types to check existing types
2. •manage_data_types with operation: create and type_kind: struct to create structures
3. •Add fields with proper offsets and types
4. •Use manage_data_types with operation: update to modify existing types

Searching for Patterns

1. •search_memory with search_type: string for string literals
2. •search_memory with search_type: bytes for byte patterns
3. •search_memory with search_type: regex for complex patterns
4. •Follow up with find_references on interesting addresses

Bulk Operations

Use batch_operations to execute multiple changes atomically:

• •Rename multiple symbols
• •Create multiple data types
• •All operations succeed or all are rolled back

Utility Operations

Common Patterns

Pagination

Most list operations return paginated results. Use the cursor field from the response to get the next page:

{"operation": "list", "cursor": "returned_cursor_value"}

Identifying Targets

Tools accept multiple ways to identify targets:

• •By address: "address": "0x401000"
• •By name: "name": "main"
• •By ID: "symbol_id": 12345 or "function_id": "0x401000"

Address Formats

Addresses can be specified as:

• •Hex with prefix: "0x401000"
• •Hex without prefix: "401000"
• •Decimal: "4198400"

Tips

1. •Start broad, then narrow: Use list operations first, then read specific items
2. •Use filtering: Most list operations support name_filter with wildcards
3. •Check before modifying: Read the current state before making changes
4. •Use batch for related changes: Group related modifications in batch_operations
5. •Undo mistakes: Use undo_redo if something goes wrong
