Deno MCP Template
by phughesmcr
A simple template for writing MCP servers using Deno, publishing them using JSR.io, and optionally using hosting on Deno Deploy. The example server also uses Deno KV to implement a simple knowledge graph tool, and allow for session resumability.

What is Deno MCP Template?
This is a template repository for creating Model Context Protocol (MCP) servers using the Deno runtime environment. It provides a foundation for building servers that can interact with applications like Claude, leveraging Deno's features and offering options for publishing and deployment.
How to use Deno MCP Template?
To use this template, replace placeholder values with your own information. You can configure the server to run via JSR, direct URL (SSE/HTTP), or STDIO. The README provides detailed instructions and examples for each method. You can also compile the server into a binary for easier deployment. Remember to configure environment variables and fine-tune Deno permissions before deploying to production.

FAQ from Deno MCP Template
What is MCP?
What is MCP?
MCP stands for Model Context Protocol. It's a protocol that allows applications to communicate with and extend the capabilities of large language models (LLMs).
What is Deno KV?
What is Deno KV?
Deno KV is a key-value database built directly into the Deno runtime, offering fast reads and writes without additional dependencies.
Do I need to use Deno Deploy?
Do I need to use Deno Deploy?
No, Deno Deploy is optional. You can publish your server on JSR or run it locally without using Deno Deploy.
How do I publish my server on JSR?
How do I publish my server on JSR?
You need to set up a JSR.io account and replace the relevant values in the codebase to match your package name and scope. Then, the publish.yml workflow will handle the publishing process.
What permissions should I use when deploying to production?
What permissions should I use when deploying to production?
The example server runs with deno run -A
, which enables all permissions. You should fine-tune the permissions to only grant the necessary access for your server to function securely.
