Perplexity

Automated document creation with Mastra AI retries

`create_document` initiates the signature process inside your Mastra AI automated workflows. If the Eversign API rate limit kicks in, Mastra's built-in retry engine handles backoffs automatically. This prevents broken pipelines when sending high volumes of contracts. Your agent handles failures gracefully, ensuring no contract request gets lost in transit.

Dynamic business division routing

`list_businesses` retrieves the exact business IDs required for routing your electronic signatures. Passing this business directory directly to your Mastra AI agent via the MCP Server ensures correct ID matching. You can build conditional branches that check the business profile before generating a contract. This ensures compliance across multi-tenant setups without manual intervention.

Resilient template instantiation

`create_document` also instantiates reusable templates for standardized legal agreements. The Mastra AI workflow engine can trigger this tool after a webhook signals a successful payment. Human-in-the-loop approval can be enabled to require a manager's sign-off before the document is sent. This balances automation with strict operational oversight.

Setup guide

Set up Eversign (Cloud Electronic Signature) 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 Eversign (Cloud Electronic Signature) 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: "eversign-cloud-electronic-signature-mcp-client",
  servers: {
    "eversign-cloud-electronic-signature-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

const result = await agent.generate(
  "List recent Eversign (Cloud Electronic Signature) transactions"
);
console.log(result.text);
