🤖 MCP Server for Visual Studio

Bridge Visual Studio with AI Assistants using the Model Context Protocol

💡 Why This Extension?

AI coding assistants are excellent at reading and writing files - they don't need help with that.

What they CAN'T do on their own:

🧠 Access IntelliSense and semantic code understanding
🔍 Find symbol definitions, usages, and inheritance hierarchies
✏️ Perform solution-wide refactoring (rename symbols across all files)

What works BETTER through Visual Studio:

🔨 Builds - VS provides clean, structured error output (saves tokens!)
🧪 Tests - Async execution with progress tracking, optimized for AI consumption

This extension gives AI agents the IDE superpowers they're missing - not file editing, but the deep code intelligence and token-efficient operations that only Visual Studio provides.

What is MCP?

The Model Context Protocol (MCP) is an open standard that enables AI assistants to interact with development tools. This extension runs an MCP server inside Visual Studio, giving AI agents direct access to your IDE.

🚀 Quick Start

1. Start the Server

Open a solution in Visual Studio
Go to Tools → Start MCP Server
Server starts on http://localhost:3001/sdk/

2. Configure Your AI Agent

Add to your .mcp.json file:

{
  "mcpServers": {
    "vs-mcp": {
      "url": "http://localhost:3001/sdk/"
    }
  }
}

3. Start Coding with AI!

Your AI assistant can now navigate your codebase, find symbols, run builds, and refactor code directly through Visual Studio.
