How to Set Up and Use NDepend MCP Server
NDepend MCP Server is an open-source Model Context Protocol server that exposes NDepend's deep .NET code analysis capabilities directly to AI coding assistants like GitHub Copilot and Claude. It gives the AI structured, unbiased workspace data — dependency graphs, code metrics, Roslyn analyzer results, ReSharper inspections, quality gate status, and NDepend CQLinq queries — without sending raw source code to the LLM, keeping responses fast and token costs low. .NET developers and architects use it to ask natural-language questions about their codebase, automatically fix complex multi-file issues, generate custom code rules, and explore architectural dependencies.
Prerequisites
- .NET 10.0 SDK installed (required to build the server)
- NDepend redistributable downloaded from https://www.ndepend.com/download and extracted; VisualNDepend.exe run at least once to activate a license or start an evaluation
- Visual Studio 2022+ or VS Code with GitHub Copilot (agent mode) or another MCP-compatible client
- Git to clone the repository
Clone the repository and extract NDepend
Clone the NDepend MCP Server repo and place the NDepend redistributable files inside the artifacts/ndepend subdirectory as expected by the build.
git clone https://github.com/ndepend/NDepend.MCP.Server.git
# Then unzip the NDepend redistributable into:
# NDepend.MCP.Server/artifacts/ndepend/Activate NDepend license
Run VisualNDepend.exe from the artifacts/ndepend directory to start a trial or enter a license key. This step is required before the server can analyze code.
.\artifacts\ndepend\VisualNDepend.exeBuild the solution
Open the solution file in Visual Studio or build from the command line with dotnet. The compiled binaries land in artifacts/bin/.
dotnet build NDepend.Mcp.Server.sln --configuration DebugRegister the server in your MCP client
Add the stdio server entry to your MCP configuration file. In VS Code, this is .vscode/mcp.json or the global mcp.json; in Visual Studio, it is .vs/mcp.json or .mcp.json at the solution root.
{
"servers": {
"NDepend.Mcp.Server": {
"type": "stdio",
"command": "C:\\path\\to\\NDepend.MCP.Server\\artifacts\\bin\\NDepend.Mcp.StdioServer\\Debug\\net10.0\\NDepend.Mcp.StdioServer.exe",
"env": {}
}
}
}Initialize analysis in the AI assistant
In a Copilot or Claude conversation, ask the assistant to initialize NDepend against your .NET solution. This is required before any other NDepend tools can run.
Run analysis and explore results
After initialization, ask natural-language questions about code quality, dependencies, or issues. NDepend generates and executes CQLinq queries on the fly to answer them.

}
}Prompts to try
Natural language questions you can ask once the server is initialized.
- "Run NDepend analysis on my solution and give me a summary."
- "Which methods are both poorly maintainable and insufficiently tested?"
- "Show callers and callees for the OrderService class."
- "List the new issues introduced since the baseline."
- "Find Clean Architecture violations in this solution."
- "Which Roslyn Analyzer rules are failing with more than 5 issues?"Troubleshooting NDepend MCP Server
Server fails to start or logs show 'license not found'
VisualNDepend.exe must be run at least once before the MCP server can operate. Navigate to artifacts/ndepend/ and launch VisualNDepend.exe to complete license activation, then restart the MCP server.
'REQUIRED FIRST STEP' error when calling any NDepend tool
The ndepend-initialize-from-solution tool must be called before any other tool. Ask your AI assistant to 'initialize NDepend from my solution file at <path>.sln' to trigger initialization.
Build fails with .NET version mismatch
The server requires .NET 10.0 SDK. Run 'dotnet --version' to check your installed version. Download and install .NET 10.0 SDK from https://dotnet.microsoft.com/download if needed.
