everything · Summary

Official MCP test server exercising all protocol features for client builders.

wasmcp · Summary

A WebAssembly Component SDK for building composable MCP servers with Rust, Python and TypeScript support.

everything · Use cases

  • Testing MCP client implementations against all protocol features
  • Learning MCP protocol capabilities through a reference server
  • Validating client compatibility with different transport methods

wasmcp · Use cases

  • Building modular MCP servers with isolated functionality in different languages
  • Creating distributed AI tool systems where each component handles specific domain tasks
  • Developing secure, containerized MCP services with limited attack surfaces
