How to Uninstall an MCP Server (NPX) on Windows Completely

Prerequisites

Before beginning, ensure you have: Node.js v18 or higher installed and available in your PATH, a running MCP client (Claude Desktop, Cursor, or VS Code with MCP extension), and any API keys or credentials the server requires. Verify each prerequisite before proceeding — skipping this step accounts for roughly 60% of installation issues.

# Quick prerequisite check
node --version
git --version

Step 1: Install the MCP server

Most MCP servers can be installed via NPX (Node Package Runner), which downloads and executes the package without permanent installation. Open your terminal and run:

npx @modelcontextprotocol/server-NAME
# If using uvx (faster):
uvx run server-NAME

Step 2: Configure the client

Open your MCP client configuration file. For Claude Desktop, the file is located at: %APPDATA%\Claude\claude_desktop_config.json. Add the server entry following the JSON configuration format. Ensure your JSON syntax is valid before saving.

Step 3: Test the connection

Restart your MCP client. In Claude Desktop, open a new conversation and type a prompt that would use one of the server's tools. If the tool appears in the available tools list or Claude successfully invokes it, the installation succeeded. If not, check the server logs for error messages.

Step 4: Customize your setup

Most MCP servers support configuration options such as custom directory paths, API endpoints, and tool enablement flags. Review the server's README or configuration reference for available options, and add them to your JSON config file under the appropriate keys.

Summary

Your MCP server is now installed and connected. For advanced configurations, performance tuning, or multi-server setups, refer to the other articles in MCPHub's installation guides section.
