What is the DocuSeal MCP Server?
Connect your DocuSeal account to any AI agent to streamline your electronic signature processes through natural language. This MCP server provides full control over document templates and signing lifecycles.

- Template Management — List, create, and update document templates. You can even generate new templates directly from HTML content.
- Signature Requests — Create new submissions (signature requests) by linking templates to specific signers and choosing whether to send automated emails.
- Signer Tracking — Retrieve detailed information about submitters and monitor the progress of individual signature requests.
- Data Pre-filling — Update submitter information or pre-fill form fields programmatically before the document is sent for signing.
- Document Archiving — Manage the lifecycle of your documents by retrieving or deleting templates and submissions as needed.

Frequently asked questions
Can I create a document template using raw HTML code?
Yes! Use the create_template tool and provide your HTML content in the html parameter. DocuSeal will convert it into a reusable document template.
How do I send a document to multiple signers at once?
Use the create_submission tool. You can pass an array of signer objects (including email, name, and role) to the submitters parameter to initiate the signing process for everyone involved.
Is it possible to pre-fill form fields before the signer opens the document?
Absolutely. Use the update_submitter tool with the specific Submitter ID and provide a JSON object in the values parameter to map data to the form fields.
How does Mastra AI connect to MCP servers?
Create an MCPClient with the server URL and pass it to your agent. Mastra discovers all tools and makes them available with full TypeScript types.
Can Mastra agents use tools from multiple servers?
Yes. Pass multiple MCP clients to the agent constructor. Mastra merges all tool schemas and the agent can call any tool from any server.
Does Mastra support workflow orchestration?
Yes. Mastra has a built-in workflow engine that lets you chain MCP tool calls with branching logic, error handling, and parallel execution.
