Contracts and e-signature for Claude agents
Give your Claude agent the ability to generate a contract, get it signed, and collect payment through Stripe. LetSign installs as an MCP server in one click, so the whole proposal to contract to payment flow lives right inside the conversation.
START FREE FROM CLAUDE - ONE CLICKFrom conversation to signed and paid in four steps
Install the MCP
Add the LetSign MCP in Claude in one click, for free. Nothing to build, no keys to wire up before your agent can start.
Your agent drafts it
From the conversation, your agent authors a proposal or contract with the scope, terms, and pricing you agreed.
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 the agreement.
What your agent can do
Once the MCP is connected, these actions become part of your agent-native contract workflow, driven straight from the chat.
Create proposals
Turn a conversation into a structured proposal or contract, with scope, terms, and a signature block.
Offer conditional pricing
Present several pricing options in one contract. The recipient picks, and terms plus billing adjust to their choice.
Send and track status
Send the signing link and check whether it has been opened, signed, and paid, without leaving the chat.
Collect payment
Take a one-off payment or set up a subscription through your Stripe. See agent contracts with Stripe payments.
It lives inside the agent, not in a separate dashboard
Because LetSign is an MCP server, it installs directly into the agent's own workflow. There is no separate tool to open, no context to copy across, and no handoff to a human to build or send the document. Your agent drafts, sends, and tracks the contract in the same conversation where the work is already happening, and payment runs through the Stripe account you already control.
Frequently asked
How do I add contracts and e-signature to a Claude agent?
Install the LetSign MCP server in Claude in one click, for free. Once connected, your agent can draft a proposal or contract from the conversation, send a public signing link, and collect payment through your Stripe. No code and no separate integration work is required.
Is it really one-click to install?
Yes. LetSign is delivered as an MCP server, so you add it from the connectors screen in one click and it is free to install. There is nothing to build and no API keys to wire up before your agent can start drafting and sending contracts.
Does it work in Claude and Claude Code?
Yes. LetSign runs as a standard MCP server, so any MCP-capable client can use it, including Claude and Claude Code. The same proposal, signing, and payment tools are available wherever your agent runs.
How are payments handled?
Payments run through your own Stripe connection. Your agent can collect a one-off payment or set up a subscription, and the recipient pays inside the same flow right after they sign. A $0 option is a no-charge agreement that signs without sending anything to Stripe.
