AI Meta MCP Server

A dynamic MCP server that allows AI models to create and execute their own custom tools through a meta-function architecture. This server provides a mechanism for AI to extend its own capabilities by defining custom functions at runtime.

Features

  • Dynamic Tool Creation: AI can define new tools with custom implementations
  • Multiple Runtime Environments: Support for JavaScript, Python, and Shell execution
  • Sandboxed Security: Tools run in isolated sandboxes for safety
  • Persistence: Store and load custom tool definitions between sessions
  • Flexible Tool Registry: Manage, list, update, and delete custom tools
  • Human Approval Flow: Requires explicit human approval for tool creation and execution

Security Considerations

⚠️ WARNING: This server allows for dynamic code execution. Use with caution and only in trusted environments.

  • All code executes in sandboxed environments
  • Human-in-the-loop approval required for tool creation and execution
  • Tool execution privileges configurable through environment variables
  • Audit logging for all operations

Installation

npm install ai-meta-mcp-server

Usage

Running the server

npx ai-meta-mcp-server

Configuration

Environment variables:

  • ALLOW_JS_EXECUTION: Enable JavaScript execution (default: true)
  • ALLOW_PYTHON_EXECUTION: Enable Python execution (default: false)
  • ALLOW_SHELL_EXECUTION: Enable Shell execution (default: false)
  • PERSIST_TOOLS: Save tools between sessions (default: true)
  • TOOLS_DB_PATH: Path to store tools database (default: "./tools.json")

Running with Claude Desktop

Add this to your claude_desktop_config.json:

{
  "mcpServers": {
    "ai-meta-mcp": {
      "command": "npx",
      "args": ["-y", "ai-meta-mcp-server"],
      "env": {
        "ALLOW_JS_EXECUTION": "true",
        "ALLOW_PYTHON_EXECUTION": "false",
        "ALLOW_SHELL_EXECUTION": "false"
      }
    }
  }
}

Tool Creation Example

In Claude Desktop, you can create a new tool like this:

Can you create a tool called "calculate_compound_interest" that computes compound interest given principal, rate, time, and compounding frequency?

Claude will use the define_function meta-tool to create your new tool, which becomes available for immediate use.

Architecture

The server implements the Model Context Protocol (MCP) and provides a meta-tool architecture that enables AI-driven function registration and execution within safe boundaries.

    I've been using the ai-meta-mcp-server by alxspiker and it's simply outstanding! The seamless integration and efficient performance of this server are remarkable. The clear documentation on the GitHub page makes it easy to set up and use. Highly recommended for anyone needing a robust MCP server solution.
