"Eclipsed" means a higher-priority definition already exists and the duplicate lower-priority entry is suppressed. Remove any manually added `microsoft-learn` entry from your `~/.mcp.json` or workspace `.mcp.json` to avoid conflicts. The built-in server will then become active automatically. No additional configuration is required for Visual Studio users. | ### 🆘 Getting Support
