Install

Pick the AI app you use, then copy the settings.

Before you install

Basic checks: 1 of 1 passed
Runs on your computer with your user’s permissions (files, network, apps).
The registry lists no key to fill in.

Which app do you use?

ClaudeClaude CodeCursorVS CodeChatGPT

Pick your app above. We remember it, so next time the button says “Install in …”.

Open Claude Desktop → Settings → Developer → Edit Config, and paste this into claude_desktop_config.json

{
  "mcpServers": {
    "projgraph": {
      "command": "dnx",
      "args": [
        "ProjGraph.Mcp",
        "--yes"
      ]
    }
  }
}

Run this in your terminal

claude mcp add projgraph -- dnx ProjGraph.Mcp --yes

Open in Cursor

Or copy the settings yourself

Paste into .cursor/mcp.json in your project, or ~/.cursor/mcp.json

{
  "mcpServers": {
    "projgraph": {
      "command": "dnx",
      "args": [
        "ProjGraph.Mcp",
        "--yes"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

Open in VS Code

Or copy the settings yourself

Paste into .vscode/mcp.json in your project

{
  "servers": {
    "projgraph": {
      "type": "stdio",
      "command": "dnx",
      "args": [
        "ProjGraph.Mcp",
        "--yes"
      ]
    }
  }
}

Your browser asks to open the app, then the app shows the settings and asks you to confirm. Key values are left empty for you to fill in.

This one runs on your computer, and ChatGPT can only connect to servers on the internet. Pick another app.

Your choice stays on this device in a cookie; no account needed.

These settings are generated from the maker’s registry entry. If the README says otherwise, follow the README.

What it can do

Common questions

Is ProjGraph MCP Server safe?

It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.2.0) reached the registry 2 months ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. You also need .NET on your computer.

What can I use instead?

ProjGraph

.NET tool ecosystem for visualizing project dependencies, database schemas, and class hierarchies.

ProjGraph is a .NET tool ecosystem for visualizing project dependencies, database schemas, and class hierarchies. It provides both a CLI for manual analysis and an MCP server for AI-assisted exploration of your codebase architecture.

🚀 Quick Start

CLI Tool

Install and use the command-line tool for immediate visualization:

# Install

dotnet tool install -g ProjGraph.Cli

Visualize project dependencies

projgraph visualize ./MySolution.slnx

Generate Entity Relationship Diagram (from DbContext or ModelSnapshot)

projgraph erd ./Data/MyDbContext.cs

Generate Class Diagram for a class and its hierarchy

projgraph classdiagram ./Models/User.cs

Compute key solution metrics (project counts, depth, hotspots)

projgraph stats ./MySolution.slnx

📖 Full CLI Documentation

MCP Server

Configure your MCP client (e.g., GitHub Copilot, Claude) with the following settings:

Find the latest version number on NuGet

"servers": { "ProjGraph.Mcp": { "type": "stdio", "command": "dnx", "args": ["ProjGraph.Mcp@x.x.x", "--yes"] } } }

📖 Full MCP Documentation

✨ Key Features

📊 Multiple Output Formats: ASCII tree and Mermaid.js diagrams
🗄️ Entity Relationship Diagrams: Generate ERDs from EF Core DbContext or ModelSnapshot files
🏗️ Class Hierarchies: Visualize class diagrams with inheritance and dependencies
📈 Solution Metrics: Project counts, type breakdown, dependency depth, and hotspot detection
📁 Modern .NET Support: Full support for .slnx, .sln, and .csproj files
🤖 AI Integration: MCP server for GitHub Copilot, Claude, and other AI assistants
⚡ Fast & Reliable: Efficient parsing and graph algorithms

🛠️ Development

Prerequisites

.NET 10.0 SDK or later

Run Locally

# CLI

dotnet run --project src/ProjGraph.Cli -- visualize ./ProjGraph.slnx

Stats

dotnet run --project src/ProjGraph.Cli -- stats ./ProjGraph.slnx

MCP Server

dotnet run --project src/ProjGraph.Mcp

📝 Usage Examples

Analyze Project Dependencies

# Mermaid format (default)

projgraph visualize ./MySolution.sln

ASCII tree format

projgraph visualize ./MySolution.sln --format tree

Mermaid format for documentation

projgraph visualize ./MySolution.slnx --format mermaid --output docs/dependencies.mmd

Generate Database Diagrams

# Generate ERD from DbContext

projgraph erd ./Data/MyDbContext.cs

Generate ERD from ModelSnapshot (leveraging migrations)

projgraph erd ./Migrations/MyDbContextModelSnapshot.cs

Output to Markdown for documentation

projgraph erd ./Data/MyDbContext.cs --output docs/database-schema.md

Control how EF Core owned types (OwnsOne/OwnsMany) are rendered:

'mirror' (default) inlines a table-split owned type onto its owner as EF names it;

'classic' gives every owned type its own entity box regardless of table mapping

projgraph erd ./Data/MyDbContext.cs --owned-mode classic

Visualize Class Hierarchies

# Generate diagram for a class and its inheritance and dependencies

projgraph classdiagram ./Models/Admin.cs -i -d

Control discovery depth (default: 1)

projgraph classdiagram ./Models/Admin.cs -i -d --depth 5

Analyze Solution Metrics

# Display project counts, depth stats, and hotspot projects

projgraph stats ./MySolution.slnx

Show top 10 most-referenced projects

projgraph stats ./MySolution.slnx --top 10

With AI Assistants

Once the MCP server is configured:

You: "Analyze the dependencies in my solution"

AI: [Generate the architecture diagram]

You: "Generate a class diagram for the User class" AI: [Generates the class hierarchy]

You: "Show me the entity relationships in my DbContext" AI: [Generates the database schema]

You: "Give me a health summary of my solution" AI: [Returns project counts, depth stats, and hotspot projects]
