Motoko MCP Server Template for ICP Ninja

Welcome! This template provides a complete, ready-to-deploy Motoko MCP server for the Prometheus Protocol ecosystem, adapted for the ICP Ninja online IDE.

No need to install anything on your machine to get started. Let's dive in.

The ICP Ninja Workflow

In this IDE, you don't use a terminal for deployment. Instead, you have two main buttons:

• Run: Deploys your server to a temporary canister. This canister is free and perfect for testing, but it will be automatically destroyed after 45 minutes.
• Publish: Deploys your server to a permanent canister that you control. To use this, you'll need to have an account with ICP and cycles to power your application.

Part 1: Quick Start (Deploy in 60 Seconds)

This section will get your server live and testable in minutes.

Step 1: Deploy a Temporary Server

Click the Run button in the ICP Ninja interface.

Wait for the deployment process to complete. You'll see the output in the console panel, which will include your new temporary canister ID.

Step 2: Test with the MCP Inspector

Your server is now live with a couple default resources and a default get_weather tool. Let's test it.

1. Copy your Canister ID from the deployment output panel.
2. Construct the Inspector URL: Create a URL with this format:

   https://[YOUR_CANISTER_ID].icp0.io/mcp
   

3. Run MCP Inspector: From your terminal, run:

   npx @modelcontextprotocol/inspector
   

4. Open the URL: The MCP Inspector will open a browser tab. Enter your URL to your MCP server in the box and click 'connect'. You can now list and fetch resources and tools, and invoke the get_weather tool (spoiler alert, its always sunny!).

🎉 Congratulations! You have a working MCP server running on the Internet Computer.

Part 2: Unlocking Advanced Features (Local Development)

The ICP Ninja IDE is fantastic for quick deployments and testing. However, to unlock features like monetization (OAuth) and publishing to the Prometheus App Store, you'll need to download this project and work with it on your local machine.

Here's a brief overview of how that works.

Prerequisites for Local Development

If you decide to download the code, you'll need these tools on your system:

1. DFX: The DFINITY Canister SDK. Installation Guide.
2. Node.js: Version 18.0 or higher. Download.
3. MOPS: The Motoko Package Manager. Installation Guide.

Enabling Monetization 💰

Ready to add paid tools? The process involves enabling the Prometheus OAuth flow.

1. Activate Auth Code: In src/main.mo, you'll uncomment the block of code that initializes the authContext.
2. Deploy Changes: Run dfx deploy (or npm run deploy) from your local terminal.
3. Register with Auth Server: Use a built-in script to register your server as a client with the Prometheus Auth Server.

   # This command is run locally, not in the IDE
   npm run auth register
   

Publishing to the Prometheus App Store 🚀

To make your server discoverable, you can submit it for verification.

1. Initialize Manifest: A command-line wizard helps you create a prometheus.yml manifest file.

   # Run locally
   npm run app-store init
   

2. Submit for Verification: Once your manifest is complete (including a Git commit hash), you submit it for an audit.

   # Run locally
   npm run app-store submit
   

3. Publish WASM: After a successful audit, you publish the final, verified code to the Prometheus Registry.

   # Run locally
   npm run app-store -- publish --app-version "0.1.0"
