概述

一个模型上下文协议（MCP）服务器，利用 Roslyn 编译器平台提供 C# 代码分析能力。该工具帮助验证 C# 文件、寻找符号引用，并在 .NET 项目上下文中执行静态代码分析。

特色

• 代码验证：分析C#文件中的语法错误、语义问题和编译器警告
• 符号引用查找：查找项目中符号的所有用法
• 项目上下文分析：在项目上下文中验证文件
• 代码分析器支持：运行Microsoft推荐的代码分析器

工具

• ValidateFile：使用 Roslyn 验证 C# 文件并运行代码分析器
• FindUsages：查找指定位置符号的所有引用

示例配置

示例提示

Roslyn Code Analysis MCP Server

Overview

A Model Context Protocol (MCP) server that provides C# code analysis capabilities using the Roslyn compiler platform. This tool helps validate C# files, find symbol references, and perform static code analysis within the context of a .NET project.

Features

• Code Validation: Analyze C# files for syntax errors, semantic issues, and compiler warnings
• Symbol Reference Finding: Locate all usages of a symbol across a project
• Project Context Analysis: Validate files within their project context
• Code Analyzer Support: Run Microsoft recommended code analyzers

Tools

• ValidateFile: Validates a C# file using Roslyn and runs code analyzers
• FindUsages: Finds all references to a symbol at a specified position

Example config

{
    "servers": {
        "RoslynMCP": {
            "type": "stdio",
            "command": "dotnet",
            "args": [
                "run",
                "--no-build",
                "--project",
                "E:/Source/roslyn-mcp/RoslynMCP/RoslynMCP/RoslynMCP.csproj"
            ]
        }
    }
}

Example prompt

When done implementing changes, run these validation steps as human will not accept work unless these are done:
- Always use Roslyn validation tool on C# (.cs) files

Getting Started

1. Build the project
2. Run the application with:

   dotnet run
   

3. The server will start and listen for MCP commands via standard I/O

Requirements

• .NET SDK
• MSBuild tools
• NuGet packages for Roslyn analyzers (automatically loaded if available)

Example Usage

Validate a C# file:

ValidateFile --filePath="/path/to/your/file.cs" --runAnalyzers=true

Find all usages of a symbol:

FindUsages --filePath="/path/to/your/file.cs" --line=10 --column=15

Technical Details

• Uses Microsoft.CodeAnalysis libraries for code analysis
• Integrates with MSBuild to load full project context
• Supports standard diagnostic analyzers
• Includes detailed output with syntax, semantic, and analyzer diagnostics
