インストール

クライアントを選択

~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "ghidrassistmcp": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/symgraph/GhidrAssistMCP"
      ]
    }
  }
}

Claude Desktop → Settings → Developer → Edit Config を開く。保存後、アプリを再起動。

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {
    "ghidrassistmcp": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/symgraph/GhidrAssistMCP"
      ]
    }
  }
}

Cursor は Claude Desktop と同じ mcpServers スキーマを使用。プロジェクト設定はグローバルより優先。

VS Code → Cline → MCP Servers → Edit

{
  "mcpServers": {
    "ghidrassistmcp": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/symgraph/GhidrAssistMCP"
      ]
    }
  }
}

Cline サイドバーの MCP Servers アイコンをクリックし、"Edit Configuration" を選択。

~/.codeium/windsurf/mcp_config.json

{
  "mcpServers": {
    "ghidrassistmcp": {
      "command": "TODO",
      "args": [
        "See README: https://github.com/symgraph/GhidrAssistMCP"
      ]
    }
  }
}

Claude Desktop と同じ形式。Windsurf を再起動して反映。

~/.continue/config.json

{
  "mcpServers": [
    {
      "name": "ghidrassistmcp",
      "command": "TODO",
      "args": [
        "See README: https://github.com/symgraph/GhidrAssistMCP"
      ]
    }
  ]
}

Continue はマップではなくサーバーオブジェクトの配列を使用。

~/.config/zed/settings.json

{
  "context_servers": {
    "ghidrassistmcp": {
      "command": {
        "path": "TODO",
        "args": [
          "See README: https://github.com/symgraph/GhidrAssistMCP"
        ]
      }
    }
  }
}

context_servers に追加。保存時に Zed がホットリロード。

claude mcp add ghidrassistmcp -- TODO 'See README: https://github.com/symgraph/GhidrAssistMCP'

ワンライナー。claude mcp list で確認、claude mcp remove で削除。

ユースケース

実用的な使い方： GhidrAssistMCP

How to analyze an unknown binary with AI assistance in Ghidra

👤 Security researchers and malware analysts working in sandboxed environments ⏱ ~60 min advanced

使うタイミング： You have a binary to analyze and want AI to help understand its functionality.

前提条件

Ghidra 11.4+ with GhidrAssistMCP installed — Download release ZIP, install via File → Install Extensions
MCP client (e.g., Claude Desktop) — Configure to connect to GhidrAssistMCP's HTTP endpoint

フロー

Get binary overview

Get the binary info and list all imports. What libraries does this binary depend on and what do the imports suggest about its functionality?✓ コピーしました

→ Binary metadata with categorized import analysis
Analyze key functions

Find functions that reference network-related strings. Decompile the most interesting one and explain what it does.✓ コピーしました

→ Decompiled C code with annotated explanation
Rename and annotate

Based on our analysis, rename the functions we've identified with descriptive names and add comments explaining their purpose.✓ コピーしました

→ Confirmation of renamed symbols

結果： A partially annotated binary with key functions identified, named, and documented.

注意点

Large binaries with thousands of functions overwhelm the analysis — Start with imports and strings to identify interesting functions, then focus on those

組み合わせ： filesystem

Solve a CTF binary reverse engineering challenge with Ghidra and AI

👤 CTF participants tackling reverse engineering challenges ⏱ ~45 min intermediate

使うタイミング： You have a CTF binary that needs to be reversed to find a flag.

前提条件

Ghidra with GhidrAssistMCP — Install the extension and load the challenge binary

フロー

Find the main logic

Search for functions that reference 'flag', 'correct', 'wrong', or 'password'. Decompile the most relevant one.✓ コピーしました

→ Decompiled function with validation logic
Trace the check

Follow the xrefs from the validation function. What data does it compare against and what transformation is applied to the input?✓ コピーしました

→ Detailed analysis of the check algorithm with data references

結果： Understanding of the validation logic sufficient to derive the flag.

注意点

Obfuscated binaries resist straightforward decompilation — Use get_basic_blocks to understand control flow, then analyze blocks individually

組み合わせ

他のMCPと組み合わせて10倍の力を

ghidrassistmcp + filesystem

Export analysis results and annotated code to files for reporting

Export the decompiled code and our annotations for the network functions to a report file.✓ コピーしました

ツール

このMCPが提供する機能

ツール	入力	呼び出すタイミング
get_binary_info	none	Get metadata about the loaded binary
get_functions	offset?: int, limit?: int	List functions in the binary
analyze_function	address: str	Decompile and analyze a specific function
search_strings	pattern: str	Search for strings in the binary
xrefs	address: str, action: str	Find cross-references to/from an address
rename_symbol	old_name: str, new_name: str	Rename a function or variable
get_imports	none	List all imported functions
get_basic_blocks	function_address: str	Get control flow blocks for a function

コストと制限

運用コスト

APIクォータ: N/A — fully local
呼び出しあたりのトークン: 200–2000 tokens (decompilation results can be large)
金額: Free — both Ghidra and GhidrAssistMCP are free
ヒント: Use search_functions_by_name and search_strings to narrow targets before decompiling.

セキュリティ

権限、シークレット、影響範囲

認証情報の保管： N/A

データ送信先： Local only — Ghidra analysis stays on your machine

⚠ This tool is designed for authorized security research, CTF competitions, and defensive analysis only. Do not use it against systems you don't own or have written authorization to test.
Only analyze binaries you have legal right to reverse engineer.

トラブルシューティング

よくあるエラーと対処法

Plugin not showing in Ghidra

Ensure you installed the extension ZIP via File → Install Extensions, then restarted Ghidra. Enable via File → Configure → Configure Plugins.

確認： Search for 'GhidrAssistMCP' in the plugin configuration dialog

MCP client can't connect

Check the GhidrAssistMCP port in the plugin settings. Ensure no firewall blocks the connection.

確認： Check the Ghidra console for MCP server startup messages

Decompilation fails for a function

Some functions (especially obfuscated ones) may fail to decompile. Try disassembly instead, or fix the function boundaries with define_func.

確認： Use get_code as a fallback

代替案

GhidrAssistMCP 他との比較

代替案	代わりに使う場面	トレードオフ
reverse-engineering-assistant	You want a tool-driven approach optimized for LLM interaction with focus on context management	Fewer tools but designed to reduce LLM hallucinations
ida-pro-mcp	You prefer IDA Pro over Ghidra for binary analysis	IDA Pro is commercial ($) but has broader format support and faster analysis
