Multiverse MCP Server: Enabling Isolated Instances of AI Applications

Overview: What is Multiverse MCP Server?

The Multiverse MCP Server is a middleware solution designed to facilitate multiple isolated instances of the same MCP servers, allowing them to coexist independently while maintaining unique namespaces and configurations. This capability makes it an invaluable tool for developers who need to run multiple instances of the same server type (like MySQL or Git) with distinct settings, ensuring that separate contexts or projects can operate seamlessly without conflicts.

🔧 Core Features & MCP Capabilities

The Multiverse MCP Server offers several core features that significantly enhance AI application integration. These include:

• Run Multiple Instances: The ability to run multiple instances of the same MCP server type (e.g., mcp-server-mysql, mcp-server-git, and mcp-server-filesystem) independently within isolated universes, each with its own configuration.

• Automatic Server Restart: Register your server during development with file watching capability. The Multiverse MCP Server will detect changes in the specified directory and perform a graceful restart, ensuring seamless testing and development.

• JSON-based Configuration System: Users can define their setup using a flexible JSON format that supports detailed configurations for each server instance, including command execution, environment variables, path resolution rules, file watching settings, and more.

Each feature is designed to provide robust AI application integration capabilities, making it easier for developers to manage multiple instances of various server types within a single project. The JSON configuration system, in particular, offers flexibility and customization that can accommodate diverse deployment scenarios.

⚙️ MCP Architecture & Protocol Implementation

The Multiverse MCP Server leverages Model Context Protocol (MCP) to enable seamless integration between AI applications and data sources or tools. The protocol flow diagram below outlines the fundamental interactions between an AI application, a MCP client, a MCP server, and external resources/tools.

This diagram illustrates the key steps involved in a typical interaction, from an AI application initiating requests through MCP clients and servers to accessing external data sources or tools. The server acts as the intermediary, ensuring that each instance operates independently within its universe while maintaining coherence with the broader MCP framework.

🚀 Getting Started with Installation

To get started with the Multiverse MCP Server, follow these steps:

1. Ensure Prerequisites: Download and install the Claude Desktop app and verify that npm is installed on your system.
2. Add Configuration to claude_desktop_config.json:
   • Locate the JSON configuration file in your operating system's default path (e.g., Mac: ~/Library/Application\ Support/Claude/claude_desktop_config.json, Windows: C:\Users\<username>\AppData\Roaming\Claude\claude_desktop_config.json).
3. Configure Servers to Be Run:
   • To run two instances (one for your job and one for a side project), add the following configuration:

{
  "mcpServers": {
    "job-multiverse": {
      "command": "npx",
      "args": [
        "-y",
        "@lamemind/mcp-server-multiverse@latest",
        "/path/to/your/job-multiverse.json"
      ]
    },
    "side-project-multiverse": {
      "command": "npx",
      "args": [
        "-y",
        "@lamemind/mcp-server-multiverse@latest",
        "/path/to/your/side-project-multiverse.json"
      ]
    }
  }
}

This configuration ensures that the Multiverse MCP Server starts when you launch the Claude Desktop application.

💡 Key Use Cases in AI Workflows

The Multiverse MCP Server supports multiple use cases critical to modern AI workflows, including:

1. Multiple MySQL Servers: Running different instances of mcp-server-mysql with distinct database configurations can help manage separate projects or environments without conflicts.
2. Filesystem Access Control: Using mcp-server-filesystem allows developers to control access and operations on files based on the configured root path while maintaining isolation between universes.

Example Implementation: Running Multiple MySQL Servers

{
  "serverName": "JobMultiverse",
  "functionsPrefix": "job",
  "servers": [
    {
      "command": "npx",
      "args": [
        "-y",
        "@benborla29/mcp-server-mysql"
      ],
      "env": {
        "MYSQL_HOST": "127.0.0.1",
        "MYSQL_PORT": "3306",
        "MYSQL_USER": "root",
        "MYSQL_PASS": "",
        "DATABASE_NAME": "job_db"
      }
    },
    {
      "command": "npx",
      "args": [
        "-y",
        "@benborla29/mcp-server-mysql"
      ],
      "env": {
        "MYSQL_HOST": "127.0.0.1",
        "MYSQL_PORT": "3306",
        "MYSQL_USER": "root",
        "MYSQL_PASS": "",
        "DATABASE_NAME": "sideproject_db"
      }
    }
  ]
}
