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
  • Lightweight enough for resource-constrained environments
  • Support all 3 protocols in the spec: stdio, sse and streamble-http.
  • Deploy anywhere: serverless, edge, mobile, IoT devices
  • Cross-platform compatibility out of the box

Security

Built with security-first mindset:

  • Sandboxed plugins that can't access your system without permission
  • Memory-safe execution with resource limits
  • Secure plugin distribution through container registries
  • Fine-grained access control for host functions
  • OCI plugin images are signed at publish time and verified at load time with sigstore.
