MCPOpen Source20.0

by lotharschulz • Tools & CLI

A simple MCP server example that exposes a Rust (WASM) function to Claude Desktop via the Model Context Protocol.

Example Use Cases

1
Execute lightweight Rust/WASM functions (e.g., factorial) via a local MCP server.
2
An example of how to configure Claude Desktop to call local MCP server functions.
3
A minimal testbed to validate Rust-to-WASM build and integration with MCP clients.

Description

This repository demonstrates how to build and expose a Rust function (compiled to WebAssembly) and connect it to an MCP-compatible client such as Claude Desktop. It includes build and release steps for the Rust/WASM code, instructions to configure Claude Desktop to point to a local MCP server, and troubleshooting tips for common import issues. The package is useful as a minimal working example for integrating custom functions into an MCP-enabled assistant.
