ZapToMCP

What is ZapToMCP?

ZapToMCP is a monorepo containing TypeScript tools and libraries for building Model Context Protocol (MCP) servers and clients. It streamlines the creation and deployment of MCP-compatible services, providing transport implementations (in-memory, SSE, Stdio, Streamable HTTP) and a type-safe API built with Fastify.

How to use ZapToMCP?

Install the SDK via pnpm add @zaptomcp/sdk (requires Node.js 20+ and pnpm 10.8.1+). Use the exported McpServer and Client classes to create servers/clients, then connect them to a transport (e.g., FastifyTransport or HTTPClientTransport). For the monorepo, clone the repository and run pnpm install && pnpm bootstrap.
