About Roslyn Workbench MCP

Roslyn Workbench MCP is an MCP server published by the GitHub account lantean-code. Bring Visual Studio-style C# fixes and refactorings to your AI agent with local Roslyn Code Actions.

It runs on your own machine: your AI client starts it from the NuGet package Lantean.Roslyn.Workbench.Mcp at version 1.1.0.

It asks for no keys or passwords.

Version 1.1.0 was published on 20 October 2026, and the source code is public, so you can read it before installing.

Written from the registry entry. 7 automated checks on registry metadata: 4 pass, 0 warn, 0 fail, 3 info. How we check.

What it asks for

This server declares no environment variables, so it asks for no keys or settings.
