Visual Studio Mcp Server
MCP Server for Visual Studio bridges your IDE with AI coding assistants like Claude Code, Cursor, Windsurf, and Cline.
Unlike file-based tools, this extension provides what AI agents CAN'T do alone:
• IntelliSense & semantic code understanding (powered by Roslyn)
• Symbol search - definitions, usages, inheritance hierarchies
• Solution/project navigation and document outlines
• Build execution with clean, structured error output
• Async test execution with progress tracking
• Solution-wide refactoring (rename symbols across all files)
20 tools designed for AI consumption with token-efficient output.
Windows only. Supports VS 2022 (17.13+) and VS 2026.

🤖 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.

Zhipu Web SearchZhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
