## Description

mcpx is a dynamic, reprogrammable MCP Server. You install new MCP servlets from mcp.run which are secure and portable WebAssembly modules. When you install a servlet from mcp.run, it will appear in your MCP Client (like Claude Desktop) ready to use - no additional configuration needed.

- Security
WebAssembly (Wasm) provides sandboxed execution, ensuring code runs safely and securely in any environment without compromising your system.

-  Portability
Write once, run anywhere. Wasm code works across platforms, languages, and environments such as your laptop, the cloud, the edge, the browser, your mobile device, and more!

-  User Experience
Users (or agents) don't need to install and configure a node or python service. They can search, install, and configure tools without leaving their client.
