Automated contract workflows

Mastra AI agents use `create_document_from_template` to kick off legal processes. If a document fails to generate, your workflow engine handles the retry automatically. This keeps your operations moving. You define the logic once and let the agent handle the execution steps.

Conditional document monitoring

Chain `list_webhooks` and `get_document` to track when a user signs a contract. You can branch your workflow based on the document status returned by the server. This allows for complex logic like notifying an admin if a signature is delayed. Your agent acts based on the actual state of the file.

Centralized audit logs

Use `get_audit_logs` to feed compliance data into your Mastra AI agents. The crew can analyze these logs to ensure every step in your contract lifecycle meets internal standards. This provides a clear trail for every document. You get automated oversight of your entire signing process.

Setup guide

Set up Modusign 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 Modusign 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: "modusign-mcp-client",
  servers: {
    "modusign-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Modusign MCP in Mastra AI

Mastra AI uses built-in retry logic. If a call to a Modusign tool hits a network snag, the workflow engine automatically attempts the action again based on your settings.

Absolutely. You can chain tools like `list_templates` and `create_document_from_template` to build multi-step contracts that require no human intervention.

Define the server in your MCP client configuration and spread the tools into your agent definition. This makes every Modusign function available to your workflow.

Yes. You can require approval for any tool call, so you check the document details before the agent sends it out for a signature.

Your audit logs are handled through a secure MCP tunnel. Only your defined agents have access to the sensitive document metadata and signing records.
