Can this be used with Visual Studio 2026? If so, could I have some guidance.

Hello👋, this might not be a useful reply since i don't know the exact answer. But here is what i know:

MCP for Unity works by bridging your unity editor with an AI assistant (Claude, Cursor, Windsurf, etc) through the Model Context Protocol. The actual requirements are just:

• Unity 2021.3 LTS or newer
• Python 3.10+ (with uv)
• An MCP client of your choice

Visual Studio 2026 can technically be one of those MCP clients if it supports MCP, but the docs don't list it explicitly. The clients with documented supports right now are:

• Claude Desktop
• Claude Code
• Cursor
• VS Code (Copilot) [which is different than just 'Visual Studio']
• Windsurf
• Cline
• And a few others

So the honest answer is: if Visual Studio 2026 has MCP client support built in (similar to how VS Code relies on the Copilot extension for this), you should be able to wire it up manually by pointing it at http://localhost:8080/mcp. If it doesn't, you'd need to pair it with one of the supported clients separately, and Visual Studio would just be your code editor as usual, while something like Cursor handles the AI side

Worth checking if VS 2026 ships with a Copilot or MCP extension, from a quick google search (1) (2), i can see that it does! (so it should work)

To wire it up, you'd add MCP for Unity's local server to your .mcp.json config file in Visual Studio:

{
  "servers": {
    "unityMCP": {
      "type": "http",
      "url": "http://localhost:8080/mcp"
    }
  }
}

Make sure that you've installed the Unity MCP from Git URL

https://github.com/CoplayDev/unity-mcp.git?path=/MCPForUnity#main

and follow the setup wizard

MCP for Unity has no Visual Studio entry in its client list (the configurators on beta are in MCPForUnity/Editor/Clients/Configurators/: VS Code, Rider, Cursor and others, but not Visual Studio), so you add it by hand.

Visual Studio 2026 (and 2022 17.14+) supports MCP servers in GitHub Copilot's Agent mode. It reads server config from several places, including %USERPROFILE%\.mcp.json (all solutions) and <SOLUTIONDIR>\.mcp.json (Microsoft docs). The format has a top-level servers key, which is the same layout the package already writes for VS Code (ConfigJsonBuilder.GetContainerKey returns "servers" for VS Code-style clients).

With the default HTTP transport (start the server from Window → MCP for Unity first):

{
  "servers": {
    "unityMCP": {
      "type": "http",
      "url": "http://127.0.0.1:8080/mcp"
    }
  }
}

That URL is the package's default local endpoint (HttpEndpointUtility: http://127.0.0.1:8080 + /mcp). If you changed the port, use the one shown in the MCP for Unity window. For stdio, pick VSCode GitHub Copilot in the client dropdown and open the manual configuration foldout. It shows the same servers shape, so the unityMCP block can be copied into .mcp.json as it is.

Then in Visual Studio, open Copilot Chat, switch to Agent mode, click Tools and enable the unityMCP tools. Visual Studio turns new MCP tools off by default.

I haven't run this in VS 2026 myself. It comes from the package source and Microsoft's docs.
