支持MCP服务器的.NET装配的无头CLI反射调试器

概览

一个由 ICSharpCode.Decompiler（dnSpyEx 引擎）驱动的静态 .NET 汇编分析模型上下文协议服务器。作为 stdio 上的 MCP 工具，公开反编译、IL 反汇编、元数据检查和保护分析。从不执行目标汇编。 - .NET 8 SDK 或更高版本 - 兼容 MCP 客户端（Claude Desktop、Cursor 或任何支持 MCP 标准传输的客户端） detect_anti_debug、detect_anti_tamper 和 get_protection_report 仅执行静态分析。目标汇编从不以 .NET 类型加载，也不会 JIT 编译，也不会执行。分析仅使用 ICSharpCode.Decompiler 的类型系统和 PE 读取器。 - 针对已知反调试 API（如 IsDebuggerPresent、NtQueryInformationProcess 等）的 P/Invoke 声明- 托管 API 使用情况（System.Diagnostics.Debugger.IsAttached 等）

dnSpy-MCP

A Model Context Protocol server for static .NET assembly analysis powered by ICSharpCode.Decompiler (dnSpyEx engine). Exposes decompilation, IL disassembly, metadata inspection, and protection analysis as MCP tools over stdio. Never executes target assemblies.

Requirements

.NET 8 SDK or later
Compatible MCP client (Claude Desktop, Cursor, or any client supporting MCP stdio transport)

Installation

git clone https://github.com/ZeraTS/dnSpy-MCP.git
cd dnSpy-MCP
dotnet build src/DnSpyMcp/DnSpyMcp.csproj -c Release

Claude Desktop Configuration

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "dnspy-mcp": {
      "command": "dotnet",
      "args": ["/path/to/src/DnSpyMcp/bin/Release/net8.0/DnSpyMcp.dll"]
    }
  }
}

`decompile_method`	Decompile a specific method to C# source code	`assemblyPath`, `typeName`, `methodName`
`dump_il`	Dump IL (CIL) disassembly for the whole assembly, a type, or a specific method	`assemblyPath`, `typeName?`, `methodName?`
`inspect_type`	Inspect a type’s structure: fields, methods, properties, interfaces, optionally with source	`assemblyPath`, `typeName`, `includeSource?`
`inspect_method`	Inspect a specific method: signature, parameters, decompiled source, optionally IL	`assemblyPath`, `typeName`, `methodName`, `includeSource?`, `includeIL?`
`list_types`	List all type definitions in the assembly	`assemblyPath`
`find_methods`	Find methods in the assembly, optionally filtered by name pattern	`assemblyPath`, `pattern?`
`search_strings`	Search for string literals in the assembly’s decompiled source	`assemblyPath`, `pattern`, `useRegex?`
`search_members`	Search for types, methods, fields, and properties by name pattern	`assemblyPath`, `pattern`
