FAQ from WASM MCP Server

What is MCP?

Model Context Protocol (MCP) is a protocol for managing and accessing models and their associated context.

What is WASM?

WebAssembly (WASM) is a binary instruction format for a stack-based virtual machine. WASM is designed as a portable target for compilation of high-level languages like C/C++/Rust, enabling deployment on the web for client and server applications.

What are the dependencies?

The project depends on @modelcontextprotocol/sdk, Zod, TypeScript, and Vite.

What are the future enhancements?

Future enhancements include additional calculator operations, persistent storage across sessions, enhanced UI/UX, additional MCP tools and resources, and WASM optimization.

Where can I find the server implementation?

The core MCP server implementation is located in server.ts within the src/web/ directory.
