Cursor MCP Installer

📢 NOW AVAILABLE ON NPM! Install with a simple npm install -g cursor-mcp-installer-free command or use directly with npx cursor-mcp-installer-free or uvx cursor-mcp-installer-free!

🔄 Latest Updates (v0.1.3): Improved path handling for all MCP server installations, better OpenAPI schema detection, and more robust server discovery in local directories. Thanks to @ItzAmirreza for submitting the initial installation path handling issue. See CHANGELOG.md for details.

Quick Start Guide

Step 1: Add to Cursor Configuration

Choose one of these methods to add the MCP Installer to your Cursor configuration:

Using npx (Easiest - No Installation Required)

Add this to your ~/.cursor/mcp.json file (create it if it doesn't exist):

{
  "mcpServers": {
    "MCP Installer": {
      "command": "npx",
      "type": "stdio",
      "args": [
        "cursor-mcp-installer-free@0.1.3",
        "index.mjs"
      ]
    }
  }
}

Using npm (Global Installation)

npm install -g cursor-mcp-installer-free@0.1.3

Then add to your ~/.cursor/mcp.json:

{
  "mcpServers": {
    "MCP Installer": {
      "command": "cursor-mcp-installer-free",
      "type": "stdio",
      "args": [
        "index.mjs"
      ]
    }
  }
}

Step 2: Restart Cursor

Close and reopen Cursor to apply the configuration changes.

Step 3: Use Claude to Install Servers

Ask Claude to install any MCP server for you:

Install the web search MCP server

or

Install the MCP server for OpenAPI schema exploration with my-schema.yaml

Step 4: What You'll See When Installed

Once properly installed and Cursor is restarted, you'll see the MCP Installer available in the sidebar when using Claude:

The MCP Installer provides three main tools:

• install_repo_mcp_server: Install MCP servers from npm packages or repositories
• install_local_mcp_server: Install MCP servers from local directories
• add_to_cursor_config: Add custom MCP server configurations

Features

• Install MCP servers from npm packages
• Install MCP servers from local directories
• Configure MCP servers for Cursor
• Add custom MCP server configurations

Prerequisites

Before using this tool, you need to have installed:

• Node.js (for npm packages)
• Cursor IDE

Installation

There are several ways to install and use the Cursor MCP Installer:

1. Using npm (Recommended)

npm install -g cursor-mcp-installer-free@0.1.3

After installation, add it to your Cursor MCP configuration file:

{
  "mcpServers": {
    "MCP Installer": {
      "command": "cursor-mcp-installer-free",
      "type": "stdio",
      "args": [
        "index.mjs"
      ]
    }
  }
}

2. Using npx (No Installation Required)

You can use npx to run the package without installing it globally:

{
  "mcpServers": {
    "MCP Installer": {
      "command": "npx",
      "type": "stdio",
      "args": [
        "cursor-mcp-installer-free@0.1.3",
        "index.mjs"
      ]
    }
  }
}

3. Direct from GitHub

Clone the repository and build it locally:

# Clone the repository
git clone https://github.com/matthewdcage/cursor-mcp-installer.git
cd cursor-mcp-installer

# Install dependencies and build
npm install
npm run build

Then configure Cursor to use your local installation:

{
  "mcpServers": {
    "MCP Installer": {
      "command": "node",
      "type": "stdio",
      "args": [
        "/path/to/cursor-mcp-installer/lib/index.mjs"
      ]
    }
  }
}

Replace /path/to/cursor-mcp-installer with the actual path where you've cloned the repository.

Where is the Cursor MCP Configuration File?

The Cursor MCP configuration file is located at:

• macOS/Linux: ~/.cursor/mcp.json
• Windows: %USERPROFILE%\.cursor\mcp.json

If the file doesn't exist, you can create it with the content from any of the installation methods above.

Path Handling Improvements in v0.1.3

Version 0.1.3 introduces significant improvements to path handling for MCP server installations:

Enhanced Path Resolution

• Properly normalizes both relative and absolute paths
• Handles paths with spaces and special characters
• Ensures consistent path formatting across different operating systems

Better Schema Detection

• Now scans all arguments for schema files, not just the first one
• Supports more schema file extensions (.yaml, .yml, .json, .openapi)
• Properly normalizes schema file paths before passing to servers

Improved Server Discovery

• Added detection of common server entry points in local directories
• Enhanced support for Python-based MCP servers
• Better error reporting for path-related issues

These improvements make the MCP Installer more robust for all types of server installations, especially when dealing with custom file paths, OpenAPI schemas, and local directory installations.

Usage

Once installed, you can use Claude or Cursor to interact with the MCP Installer. Here are some example prompts:

Install an npm package as an MCP server

Install the MCP server named mcp-server-fetch

Install with arguments

Install the @modelcontextprotocol/server-filesystem package as an MCP server. Use ['/home/user/documents'] for the arguments

Install a local MCP server

Install the MCP server at /home/user/projects/my-mcp-server

Install with environment variables
