About Capstone MCP Server

Capstone MCP Server is an MCP server published by Tokeii0 in the AI category: capstone mcp server for N8N.

The repository has 7 stars and 1 forks, with the last commit 8 months ago. Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.

Install

From source
git clone https://github.com/Tokeii0/capstone-mcp-server

This server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

Capstone MCP Server

中文 | English

基于 Capstone 反汇编引擎的 MCP (Model Context Protocol) 服务器,为大语言模型提供二进制分析能力。

功能特性

  • 多架构支持: x86 (16/32/64)、ARM/ARM64、MIPS (32/64)、PowerPC (32/64)
  • 多格式解析: PE、ELF、Mach-O 二进制文件自动识别与解析
  • 反汇编工具: 支持 hex 字节串、文件区段、虚拟地址、文件偏移等多种输入方式
  • 控制流分析: 基本块识别、跳转/调用/返回分析
  • 指令搜索: 按助记符或指令类别过滤搜索
  • 架构自动检测: 从 PE/ELF/Mach-O 文件头自动推断 CPU 架构
  • ROP Gadget 搜索: 查找以 ret 结尾的指令片段,用于 ROP 链构造
  • 安全特性检测: 类似 checksec,检测 NX/PIE/RELRO/Canary/ASLR 等
  • PLT/GOT & IAT 分析: ELF 动态链接表与 PE 导入表分析
  • 字符串提取: 支持 ASCII 和 UTF-16LE 编码的可读字符串扫描
  • XOR 编解码: 单字节暴力破解与多字节密钥 XOR 运算
  • 缓冲区溢出辅助: De Bruijn 序列生成与偏移计算(pattern_create/offset)
  • 加密常量识别: 检测 AES S-Box、SHA、MD5、TEA、CRC32、Base64 等常量
  • Shellcode 分析: NOP sled、syscall、jmp/call esp 等模式检测
  • Syscall 查找: Linux x86/x64/ARM/ARM64 系统调用表查询
  • Hex Dump: 格式化的十六进制转储查看
  • 交叉引用查询: 在代码中搜索对指定地址的所有引用(call/jump/立即数/内存访问)

安装

# 克隆项目
git clone <repo-url>
cd capstone-mcp-server

# 安装依赖
pip install -e .

运行

直接运行

capstone-mcp

通过 Python 模块运行

python -m capstone_mcp.server

使用 MCP Inspector 调试

mcp dev src/capstone_mcp/server.py

配置 MCP 客户端

Windsurf / Claude Desktop

在 MCP 配置文件中添加:

{
  "mcpServers": {
    "capstone-disasm": {
      "command": "python",
      "args": ["-m", "capstone_mcp.server"],
      "cwd": "/path/to/capstone-mcp-server"
    }
  }
}

或者使用 uv 运行:

{
  "mcpServers": {
    "capstone-disasm": {
      "command": "uv",
      "args": ["run", "--directory", "/path/to/capstone-mcp-server", "capstone-mcp"]
    }
  }
}

使用示例

反汇编 hex 字节串

大模型可调用 disassemble_hex 工具:

输入: hex_code="554889e54883ec10c745fc00000000b8000000004883c4105dc3", arch="x86_64"

输出:

Architecture: x86_64
Base Address: 0x0
Input Size:   25 bytes
────────────────────────────────────────────────────────────────
0x00000000:  55                        push     rbp
0x00000001:  4889e5                    mov      rbp, rsp
0x00000004:  4883ec10                  sub      rsp, 0x10
0x00000008:  c745fc00000000            mov      dword ptr [rbp - 4], 0
0x0000000f:  b800000000                mov      eax, 0
0x00000014:  4883c410                  add      rsp, 0x10
0x00000018:  5d                        pop      rbp
0x00000019:  c3                        ret

分析二进制文件

1. 调用 get_binary_info("C:/path/to/program.exe")  → 获取文件概要
2. 调用 disassemble_entrypoint("C:/path/to/program.exe")  → 查看入口点
3. 调用 search_instructions_in_file("C:/path/to/program.exe", group="call")  → 查找所有调用

Questions

About Capstone MCP Server

How do I install Capstone MCP Server?

No package has been published for this server, so install it from source: clone the repository and follow its README.

Is Capstone MCP Server safe to use with an AI agent?

Its trust score is 34 out of 100 (low). It passes 1 of the 1 static security checks run so far. It has no ConduID identity yet, so agent calls to it are not receipted.

Is Capstone MCP Server still maintained?

The last commit was 8 months ago. That's long enough that you should check whether the maintainer is responding to issues before depending on it.
