What is Deno MCP Template Server?

This is a ready-to-use template for creating MCP (Model Context Protocol) servers using Deno runtime. It provides all the necessary infrastructure including deployment options, database integration, and publishing capabilities.

How to use this server?

You can run the server locally, compile it to a binary, or use it directly from JSR package registry. It supports multiple connection methods including HTTP endpoint and STDIO.

Use Cases

Ideal for building knowledge graph tools, AI memory systems, or any application requiring persistent context management with Claude AI.

Key Features

Deno Runtime

Built using Deno for secure TypeScript execution with built-in tooling

Deno KV Database

Integrated key-value storage for persistent data without external dependencies

Flexible Deployment

Supports JSR publishing, Deno Deploy hosting, and binary compilation

MCP Protocol Support

Implements the Model Context Protocol specification for AI context management

Advantages

No external database required (uses Deno KV)

Simple deployment options including serverless

TypeScript support out of the box

Built-in CI/CD workflows

Limitations

Requires Deno runtime (not Node.js compatible)

KV database is currently unstable in Deno

Default configuration shares KV storage across all users

Getting Started

🚀 Deno MCP Template Repository

This repository provides a Model Context Protocol (MCP) template implemented with Deno, aiming to simplify the development process and enhance efficiency.

🚀 Quick Start

Local Run

Clone the repository:

git clone https://github.com/yourusername/deno-mcp-template.git
cd deno-mcp-template

Install dependencies: Deno handles dependencies automatically, no additional installation is required.

```
deno run -A --unstable-kv db.ts
```

Deploy to Deno Deploy

Log in to your Deno account and create an application.
Push the repository to Deno's Git service or integrate with GitHub.
Configure environment variables and deploy.

✨ Features

.github/workflows/: Contains GitHub workflows for publishing and deployment.
db.ts: Implements the knowledge graph storage logic using the Deno KV database.
vendor/schema.ts: Referenced from 2025-03-26 MCP Schema under the MIT license.

📚 Documentation

Development Information

Deno KV: A key - value database used directly in the Deno runtime, no additional configuration is needed. When running locally, it will automatically generate file storage, and Deno Deploy has built - in support.
Knowledge Graph Memory Server: Implements the knowledge graph storage logic based on MCP Example.
