Overview

The Deno MCP Server Template is a batteries-included starting point for building production MCP servers in TypeScript. It provides a complete working server with STDIO + HTTP transports, security middleware, persistent state, sandboxed execution, and CI/CD workflows out of the box. The template supports multiple distribution formats including JSR packages, native binaries, DXT extensions, and cloud deployment on Deno Deploy, making it easy to ship MCP servers anywhere with a single codebase.
