Workers + Stytch TODO App MCP Server

This is a Workers server that composes three functions:

User and client identity is managed using Stytch. Put together, these three features show how to extend a traditional full-stack application for use by an AI agent.

Set up

Follow the steps below to get this application fully functional and running using your own Stytch credentials.

In the Stytch Dashboard

  1. Create a Stytch account. Within the sign up flow select Consumer Authentication as the authentication type you are interested in. Once your account is set up a Project called "My first project" will be automatically created for you.

  2. Navigate to Frontend SDKs to enable the Frontend SDK in Test

  3. Navigate to Connected Apps to enable Dynamic Client Registration

  4. Navigate to Project Settings to view your Project ID and API keys. You will need these values later.

On your machine

In your terminal clone the project and install dependencies:

git clone https://github.com/stytchauth/mcp-stytch-consumer-todo-list.git
cd mcp-stytch-consumer-todo-list
pnpm i

Next, create an .env.local file by running the command below which copies the contents of .env.template.

cp .env.template .env.local

Open .env.local in the text editor of your choice, and set the environment variables using the public_token found on Project Settings.

# This is what a completed .env.local file will look like
VITE_STYTCH_PUBLIC_TOKEN=public-token-test-abc123-abcde-1234-0987-0000-abcd1234

Open wranger.jsonc in the text editor of your choice, and set vars.STYTCH_PROJECT_ID using the Project ID found on Project Settings.

// This is what a completed wrangler.jsonc will look like
"vars": {
   "STYTCH_PROJECT_ID": "project-test-6c20cd16-73d5-44f7-852c-9a7e7b2ccf62"
},

Running locally

After completing all the setup steps above the application can be run with the command:

pnpm run dev

The application will be available at http://localhost:3000 and the MCP server will be available at http://localhost:3000/sse.

Test your MCP server using the MCP Inspector

npx @modelcontextprotocol/inspector@latest

Deploy to Cloudflare Workers

  1. Create a KV namespace for the TODO app to use
wrangler kv:namespace create TODOS
  1. Update the KV namespace ID in wrangler.jsonc with the ID you received:
"kv_namespaces": [
   {
      "binding": "TODOS",
      "id": "your-kv-namespace-id"
   }
]
  1. Deploy the worker
pnpm run deploy
  1. Grant your deployment access to your Stytch project. Assuming your Stytch project was deployed at https://mcp-stytch-consumer-todo-list.$YOUR_ACCOUNT_NAME.workers.dev:
    1. Add https://mcp-stytch-consumer-todo-list.$YOUR_ACCOUNT_NAME.workers.dev/authenticate as an allowed Redirect URL
    2. Add https://mcp-stytch-consumer-todo-list.$YOUR_ACCOUNT_NAME.workers.dev as an allowed Authorized Application in the Frontend SDKs configuration
