Dotnetanalyzer

🚀 DotNetAnalyzer

A powerful MCP (Model Context Protocol) server tool that brings Roslyn's code analysis capabilities to Claude Code.

🚀 Quick Start

Prerequisites

• .NET 8.0 SDK or a higher version
• Claude Code (supports the MCP protocol)
• A .NET solution or project

Installation

Method 1: Install from NuGet (Recommended) ✨

DotNetAnalyzer has been published to NuGet.org!

# Install the DotNetAnalyzer tool globally
dotnet tool install --global DotNetAnalyzer

# Verify the installation
dotnet-analyzer --version

# Check the tool location
dotnet-tool list --global

NuGet package information:

• 📦 Package name: DotNetAnalyzer
• 🏷️ Version: 0.8.0
• 🔗 Link: https://www.nuget.org/packages/DotNetAnalyzer
• .NET 8.0 or a higher version

Method 2: Build from source

# Clone the repository
git clone https://github.com/CartapenaBark/DotNetAnalyzer.git
cd DotNetAnalyzer

# Restore dependencies
dotnet restore

# Build and package as a local tool
dotnet pack -c Release

# Install from the local NuGet package
dotnet tool install --global DotNetAnalyzer --add-source ./nupkg

Update

# Update to the latest version
dotnet tool update --global DotNetAnalyzer

Uninstall

dotnet tool uninstall --global DotNetAnalyzer

Configure Claude Code

Create a .mcp.json file in the project directory to configure the MCP server:

Configuration file location:

• .mcp.json - Place it in the project root directory
• User-level configuration: ~/.claude/settings.json - Applicable to all projects

{
  "mcpServers": {
    "dotnet-analyzer": {
      "command": "dotnet-analyzer",
      "args": [
        "mcp",
        "serve"
      ],
      "env": {
        "DOTNET_ENVIRONMENT": "Production",
        "DOTNET_ANALYZER_LOG_LEVEL": "Information"
      }
    }
  }
}

Or use the project-level settings.json: Create a .claude/settings.json file in the project root directory:

{
  "enabledMcpjsonServers": ["dotnet-analyzer"]
}

Then create a .mcp.json file in the project root directory (same as above).

Configuration priority:

1. Enterprise management policy (highest)
2. Command-line arguments
3. .claude/settings.local.json (local project)
4. .claude/settings.json (shared project)
5. ~/.claude/settings.json (user-level, lowest)

Supported solution formats

DotNetAnalyzer fully supports the following Visual Studio solution formats:

Usage examples:

# Use the .sln format
dotnet-analyzer mcp serve --solution MyProject.sln

# Use the .slnx format
dotnet-analyzer mcp serve --solution MyProject.slnx

Advantages of .slnx:

• 🎯 Human-readable XML structure
• 📦 More concise syntax
• 🚀 Default format for .NET CLI 9.0.200+
• ✅ Fully backward-compatible with .sln

Usage examples

After configuration, you can naturally use these features in Claude Code:

You: "Analyze all diagnostics in this project."
Claude: [Call get_diagnostics] ...
     "Found 3 errors and 15 warnings..."

You: "Who are the callers of this method?"
Claude: [Call get_caller_info] ...
     "This method is called from 5 locations..."

You: "Help me extract this part of code into a method."
Claude: [Call extract_method] ...
     "Successfully extracted into a new method CalculateTotal..."

✨ Features

DotNetAnalyzer is a .NET global tool developed using .NET 8.0/9.0/10.0. By encapsulating the powerful Roslyn (.NET Compiler Platform) API, it enables Claude Code to deeply analyze and understand C# code.

Why is DotNetAnalyzer needed?

Claude Code is a powerful AI programming assistant, but it has limitations in understanding .NET code. DotNetAnalyzer bridges this gap through the MCP protocol, offering:

• ✅ Semantic-level code analysis - Not just syntax highlighting, but real type and symbol understanding
• ✅ Intelligent code navigation - Jump to definitions, find references, and understand inheritance hierarchies
• ✅ Project management - Solution analysis, dependencies, and build order
• ✅ In-depth insights - Call graph analysis, code metrics, and complexity assessment
• ✅ Performance optimization - LRU caching, incremental analysis, and quick response

Advantages as a .NET tool

• 🚀 One-click installation - Quickly install via dotnet tool install
• 📦 Automatic updates - Supports automatic updates with dotnet tool update
• 🔧 Cross-platform - Supports Windows, macOS, and Linux
• 🎯 Zero configuration - Ready to use out of the box, no manual builds required

📦 Building and Publishing

Local build

# Build the project
dotnet build -c Release

# Run tests
dotnet test

# Run all tests (including performance tests)
dotnet test --filter "Category=Performance"

# Create a NuGet package
dotnet pack -c Release

GitHub Actions CI/CD

The project uses GitHub Actions for automated building and publishing:

• Trigger conditions: Push to the main branch, create a Release, manual trigger
• Build process:
  1. Restore dependencies
  2. Run tests (skip performance tests in the CI environment)
  3. Create a NuGet package
  4. Publish to NuGet.org (only for Releases)
  5. Create a GitHub Release

Note: Performance benchmark tests are sensitive to the running environment and will be automatically skipped in the CI environment. You can run performance tests locally using dotnet test --filter "Category=Performance".

Version strategy

• Semantic versioning: Follow SemVer 2.0
• Pre-release versions: Use -beta, -rc, etc.
• Automatic publishing: Automatically publish when pushing a Git tag
