# ILSpy MCP Server A Model Context Protocol (MCP) server that provides .NET assembly decompilation capabilities using ILSpy. ## Features - **Decompile Assemblies**: Convert .NET assemblies back to readable C# source code - **List Types**: Enumerate classes, interfaces, structs, delegates, and enums in assemblies - **Generate Diagrammer**: Create interactive HTML visualizations of assembly structure - **Assembly Information**: Get metadata about .NET assemblies ## Prerequisites 1. **ILSpy Command Line Tool**: Install the global dotnet tool: ```bash dotnet tool install --global ilspycmd ``` 2. **Python 3.8+**: Required for running the MCP server ## Installation Install from PyPI: ```bash pip install ilspy-mcp-server ``` Or for development: ```bash git clone https://github.com/Borealin/ilspy-mcp-server.git cd ilspy-mcp-server pip install -e . ``` ## Usage ### MCP Client Configuration Configure your MCP client (e.g., Claude Desktop) to use the server: ```json { "mcpServers": { "ilspy": { "command": "python", "args": ["-m", "ilspy_mcp_server.server"] } } } ``` ### Available Tools #### 1. `decompile_assembly` Decompile a .NET assembly to C# source code. **Parameters:** - `assembly_path` (required): Path to the .NET assembly file - `output_dir` (optional): Output directory for decompiled files - `type_name` (optional): Specific type to decompile - `language_version` (optional): C# language version (default: "Latest") - `create_project` (optional): Create a compilable project structure - `show_il_code` (optional): Show IL code instead of C# - `remove_dead_code` (optional): Remove dead code during decompilation - `nested_directories` (optional): Use nested directories for namespaces **Example:** ```json { "name": "decompile_assembly", "arguments": { "assembly_path": "/path/to/MyAssembly.dll", "type_name": "MyNamespace.MyClass", "language_version": "CSharp10_0" } } ``` #### 2. `list_types` List types in a…
