FrontMCP is the TypeScript-first framework for MCP. You write clean, typed code; FrontMCP handles the protocol, transport, and execution flow.

Why FrontMCP?

  • 🧑‍💻 TypeScript-native DX — decorators, Zod, and strong typing end-to-end
  • 🧠 Scoped invoker + DI — secure, composable execution with hooks
  • 🧩 Adapters & Plugins — extend your server without boilerplate
  • 🔌 Spec-aligned transport — Streamable HTTP for modern MCP clients

Core concepts

  • Server — entry point via @FrontMcp({...})
  • App — a logical bundle of tools via @App({...})
  • Tool — typed units of work via @Tool({...})
  • Hooks — cross-cutting behaviors (auth, logging, rate limits)
  • Adapters/Plugins — load tools dynamically; enrich behavior
FrontMCP follows MCP protocol principles and secured transport requirements. You get sessions, streaming, and validation out of the box—no custom wiring needed.
