  • smile_list_customers

  • smile_create_activity

    WRITE: record that a customer performed an action (identified by an activity type token configured in Smile Admin, e.g. a custom 'newsletter signup' activity). Smile then asynchronously applies the store's earning rules and may issue points or rewards. Identify the customer by cu

  • smile_purchase_points_product

    WRITE — SPENDS THE CUSTOMER'S POINTS: redeem points on the customer's behalf by purchasing a points product; Smile deducts the points and issues the reward (the response's points_purchase.reward_fulfillment usually holds a discount code). Only do this when the customer asked for

Common questions

Is Smile.io MCP by usefulapi safe?

It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed yesterday, and the latest version (1.37.3) reached the registry yesterday.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT Business and above.

What can I use instead?

Smile.io MCP by usefulapi

Use Smile.io from Claude, Cursor, or any MCP client — look up loyalty customers, points balances and history, ways to earn and redeem, issued rewards and VIP tiers, and adjust points. Hosted, no local install: connect with your own Smile.io credentials.

Live endpoint: https://smile-io.usefulapi.io/mcp · Homepage: https://usefulapi.io/smile-io

Connect

  • Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://smile-io.usefulapi.io/mcp.
  • Claude Code: claude mcp add --transport http smile-io https://smile-io.usefulapi.io/mcp, then run /mcp to log in.
  • VS Code: Add to VS Code.
  • Cursor and other clients: add the URL as a remote MCP server:
{

"mcpServers": { "smile-io": { "url": "https://smile-io.usefulapi.io/mcp" } } }

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Smile.io credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/smile-io/

On first connect you'll provide your Smile.io merchant API key (Smile Admin → Settings → Developer tools → API keys). They're validated, stored per-user, and scoped to you — no keys in config files.
