Agent contracts with Stripe payments
Let your AI agent send a contract and collect payment through your own Stripe, one-off or subscription, right inside the signing flow. LetSign installs as an MCP server in one click, so money and signature happen in a single step with no separate invoicing.

Install the MCP
Add the LetSign MCP in Claude in one click, for free. Nothing to build and no keys to wire up before your agent can start.
Your agent drafts the deal
From the conversation, your agent authors a proposal or contract with the scope, terms, and the price you want to charge.
The recipient signs
They open a public link, pick a plan, verify their email, and sign a binding e-signature. You never drive their signing.
They pay via Stripe
Payment happens in the same flow, through your own Stripe connection, right after they sign. No separate invoice to chase.
Ways your agent can get paid
Every option runs through your own Stripe as part of the contract flow for Claude agents, driven straight from the chat.
One-off payments
Charge a single amount when the recipient signs. The payment runs through your own Stripe, inside the same flow, with no separate invoice.
Subscriptions
Set up recurring billing so the recipient starts a subscription the moment they sign, all through the Stripe account you already control.
Card on file, charge later
Save a card at signing and charge it later. Useful when the amount is confirmed after the agreement, with nothing charged up front.
No-charge agreements
A $0 option signs and activates without sending anything to Stripe, so a plain agreement and a paid one share the same flow.
Money and signature in one flow, not two tools
With most tools, getting paid means signing in one place and invoicing in another. LetSign collapses that into a single step, part of an agent-native contract: the recipient signs and pays via Stripe in the same flow, so there is no separate invoicing step to chase. Payment runs through the Stripe account you already control, and your agent never touches card details because Stripe handles the checkout.
Frequently asked
How does an AI agent collect payment on a contract?
Install the LetSign MCP server in one click, for free. Your agent drafts the contract or proposal, sends a public link, and the recipient picks a plan, verifies their email, signs a binding e-signature, and pays via Stripe in the same flow. There is no separate invoicing step, and your agent never touches card details.
Do payments go through my own Stripe?
Yes. Payments run through your own Stripe connection, so the money lands in the account you already control. LetSign simply orchestrates the checkout inside the signing flow, and you keep full ownership of payouts, refunds, and reporting in your Stripe dashboard.
Can it charge subscriptions, not just one-off?
Yes. Your agent can collect a one-off payment or set up a recurring subscription through your Stripe. It can also save a card on file to charge later, and a $0 option is a no-charge agreement that signs without sending anything to Stripe.
Is card data handled securely?
Card details are entered and processed by Stripe, not by LetSign and not by your agent. The recipient pays through Stripe's own checkout, so sensitive card data never passes through the conversation or your agent, and Stripe handles the payment security.
