hyper-mcp

A fast, secure MCP server that extends its capabilities through WebAssembly plugins.

What is it?

hyper-mcp makes it easy to add AI capabilities to your applications. It works with Claude Desktop, Cursor IDE, and other MCP-compatible apps. Write plugins in your favorite language, distribute them through container registries, and run them anywhere - from cloud to edge.

Features

• Write plugins in any language that compiles to WebAssembly
• Distribute plugins via standard OCI registries (like Docker Hub)
• Built on Extism for rock-solid plugin support
• Sanboxing with WASM: ability to limit network, filesystem, memory access
• Lightweight enough for resource-constrained environments
• Support stdio transport protocol
• Deploy anywhere: serverless, edge, mobile, IoT devices
• Cross-platform compatibility out of the box
• Support tool name prefix to prevent tool names collision
• Dynamic plugin loading and unloading (configurable)

Security

Built with security-first mindset:

• Sandboxed plugins that can't access your system without permission
• Memory-safe execution with resource limits
• Secure plugin distributio
