+::::tip[For agents]
+The [Link CLI](/tools/wallet#link-cli) handles `stripe.charge` end-to-end—`link-cli mpp pay` parses the 402 Challenge, creates an SPT from the user's Link wallet, and retries the request with the Credential. No code required.
+::::
+
 Use `stripe` with `Mppx.create` to automatically handle `402` responses. The client parses the Challenge, creates an SPT through the `createToken` callback, and retries with the Credential.
 
 SPT creation requires a Stripe secret key, so the client accepts a `createToken` callback that proxies through a server endpoint. You can optionally pass a `client` (a Stripe.js instance from `@stripe/stripe-js`) which is forwarded to the `createToken` callback for use with Elements.

+## Link CLI
+
+[Link CLI](https://github.com/stripe/link-cli) lets agents pay for MPP services using a [Link](https://link.co) wallet. The agent authenticates with Link, then `link-cli mpp pay` handles the full `402` → SPT → retry flow automatically—no Stripe integration code required.
+
+The user approves each purchase via the Link app, and credentials are one-time-use tokens scoped to a specific merchant and amount.

 ## `mppx`
 
 The [`mppx`](/sdk/typescript/cli) CLI is a lightweight MPP client bundled with the `mppx` package. It handles `402` responses automatically using a local keychain account—ideal for development, testing, and debugging.
