MCP Helper Library

MCPOpen Source24.3

by mizchi • Frontend & UI

A small Deno library for building type-safe Model Context Protocol (MCP) servers with Zod validation and an in-memory test client.

Example Use Cases

1
Expose small, type-safe tools over MCP from a Deno server with Zod-validated inputs and outputs.
2
An in-memory test client to unit-test MCP tool handlers without spawning external processes.
3
A lightweight, TypeScript-first development workflow for building and iterating on MCP tool implementations.

Description

This library provides a TypeScript-first helper for creating MCP servers in Deno, offering Zod schema validation for inputs and outputs and compile-time type safety for handlers and clients. It includes an in-memory test client for easy, type-safe testing of tools and an experimental CLI integration note. The project is open-source (MIT) and geared toward developers building and testing MCP-compatible tools locally.
