Apisign MCP server

What it does

An MCP server that lets AI agents draft, manage, and send documents for legally binding e-signatures through APISign's hosted service. It exposes tools for creating and managing reusable signature templates, and for creating, editing, and sending contracts to signers.

• Draft a contract from a template, fill in variable fields like dates and names, and send it to multiple signers for e-signature.
• List existing signature templates in your organization and retrieve their field definitions to understand what data they need.
• Check the status of sent contracts, see which signers have completed their signatures, and cancel drafts or sent documents.

Before you enable it

An MCP server runs with whatever access you give it. Start with a development account rather than production, and check which tools the server exposes before you let an agent call them unattended.
