Roslyn MCP Server

A C# MCP (Model Context Protocol) server that integrates with Microsoft’s Roslyn compiler platform to provide Claude Desktop with code analysis and navigation capabilities for C# codebases.

Features

• Wildcard Symbol Search - Find classes, methods, and properties using pattern matching (*Service, Get*User, etc.)
• Reference Tracking - Locate all usages of symbols across entire solutions
• Symbol Information - Get detailed information about types, methods, properties, and more
• Dependency Analysis - Analyze project dependencies and namespace usage patterns
• Code Complexity Analysis - Identify high-complexity methods using cyclomatic complexity metrics
• Performance Optimized - Multi-level caching and incremental analysis for large codebases
• Security - Input validation and path sanitization

Prerequisites

• .NET 8.0 SDK or later
• Visual Studio 2022 or VS Code (recommended for development)
• Claude Desktop application

Installation

1. Clone or download the project

   git clone https://github.com/carquiza/RoslynMCP.git
   cd RoslynMCP/RoslynMcpServer
   

2. Restore NuGet packages

   dotnet restore
   

3. Build the project

   dotnet build
   

4. Test the server (optional)

   dotnet run
   

Quick Setup

Windows

Run the PowerShell setup script:

.\setup.ps1

Linux/macOS

Run the installation test:

./test-installation.sh

Claude Desktop Configuration

To connect this MCP server to Claude Desktop, you need to modify the Claude Desktop configuration file:

Configuration File Location

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

Configuration Content

Add the following to your claude_desktop_config.json file:

{
  "mcpServers": {
    "roslyn-code-navigator": {
      "command": "dotnet",
      "args": [
        "run", 
        "--project", 
        "/path/to/RoslynMCP/RoslynMcpServer"
      ],
      "env": {
        "DOTNET_ENVIRONMENT": "Production",
        "LOG_LEVEL": "Information"
      }
    }
  }
}

Important: Replace /path/to/RoslynMCP/RoslynMcpServer with the actual absolute path to your project directory.

Usage

Once configured, restart Claude Desktop. You should see the Roslyn MCP Server appear in the available tools. Here are some example queries:

Search for Symbols

Search for all classes ending with 'Service' in my solution at C:\MyProject\MyProject.sln

Find References

Find all references to the UserRepository class in C:\MyProject\MyProject.sln

Get Symbol Information

Get information about the CalculateTotal method in C:\MyProject\MyProject.sln

Analyze Dependencies

Analyze dependencies for the solution at C:\MyProject\MyProject.sln
