How to Use the DocuSeal MCP in Mastra AI

Q: How do I require human approval before Mastra AI sends a DocuSeal request?

Set the requireToolApproval option to true when registering the createsubmission tool in your MCP setup. This pauses the Mastra AI workflow and waits for an admin to click approve before DocuSeal dispatches the document.

Q: Can I dynamically update templates using DocuSeal and Mastra AI?

Yes, your agent can call updatetemplate to modify layout fields during active workflows. Mastra AI passes the updated schema directly to DocuSeal, ensuring the signer sees the correct fields.

Q: How do I download completed PDFs in a Mastra AI workflow?

Use getsubmissiondocuments to retrieve the PDF download URLs once the signing is complete. Your Mastra AI agent can then pass these URLs to a downstream file-storage step.

Resilient DocuSeal Workflows with Mastra AI

`create_submission` initiates the signing process inside a Mastra AI workflow step powered by this MCP server. If the recipient's email bounces, Mastra's built-in retry engine catches the failure and attempts the call again with exponential backoff. You can chain `get_submitter` right after the submission step to verify the recipient's details. The Mastra agent uses this data to decide whether to escalate the workflow or proceed to the next signing phase.

Conditional Template Management

`list_templates` scans your active DocuSeal library to find matching contract forms before triggering a workflow. Mastra AI uses conditional branching to select the correct template ID based on the customer's subscription tier. If the agent finds no suitable match, `create_template` generates a new document layout from raw HTML. This automated fallback ensures your signing pipeline never stalls due to missing assets.

Automated Signer Updates and Cleanups

`update_submitter` modifies recipient metadata on the fly when a customer changes their contact info mid-workflow. Your Mastra AI agent handles this change automatically without requiring you to write custom webhook integration code. When a transaction is aborted, `delete_submission` cancels the signing request to prevent unwanted follow-ups. The Mastra workflow logs the cancellation and triggers an email notification to your sales team.

Setup guide

Set up DocuSeal MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All DocuSeal tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "docuseal-mcp-client",
  servers: {
    "docuseal-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "DocuSeal Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to DocuSeal tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent DocuSeal transactions"
);
console.log(result.text);

Common questions about DocuSeal MCP in Mastra AI

Set the `requireToolApproval` option to true when registering the `create_submission` tool in your MCP setup. This pauses the Mastra AI workflow and waits for an admin to click approve before DocuSeal dispatches the document.

Mastra AI handles transient network errors automatically using its native retry policies. If `get_submission` fails due to a rate limit, the framework backs off and retries without crashing your execution thread.

Yes, your agent can call `update_template` to modify layout fields during active workflows. Mastra AI passes the updated schema directly to DocuSeal, ensuring the signer sees the correct fields.

Use `get_submission_documents` to retrieve the PDF download URLs once the signing is complete. Your Mastra AI agent can then pass these URLs to a downstream file-storage step.

All tool calls pass through the secure Vinkius MCP sandbox, ensuring your DocuSeal credentials remain encrypted. Mastra AI executes the MCP server tools locally or on your server, meaning signer emails and contract metadata are never exposed to external parties.
