How to Use the Modusign MCP in Vercel AI SDK

Q: What Modusign tools work best with Vercel AI SDK?

The generation tools like createdocumentfromtemplate are best for user-facing actions. Use the status tools to keep your application state in sync with actual signatures.

Stream Modusign contracts and audit logs directly into your Vercel AI SDK frontends for real-time document visibility.

Perplexity

Real-time document status in your UI

Your AI client pushes document data straight into your application interface. Use `list_documents` to pull active contracts and render them instantly without waiting for backend refreshes. This keeps your users informed. The data flows through your stream and appears on screen as soon as your agent finishes fetching it.

Generate contracts from templates

Trigger `create_document_from_template` during your application's checkout or onboarding flow. Your agent handles the document generation while the user stays within your own UI. This removes the need for redirects. You handle the template selection and document creation entirely through your SDK-connected server.

Audit trail visibility

Retrieve exact document histories using `get_audit_logs`. Your application can display who signed what and when, directly inside your dashboard. This gives your users a complete view of their document lifecycle. You show them the progress without making them jump over to the Modusign portal.

Setup guide

Set up Modusign MCP in Vercel AI SDK

Prerequisites

Node.js 18+ and a TypeScript project
ai + @modelcontextprotocol/sdk packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies

Run npm install ai @modelcontextprotocol/sdk plus your preferred model provider (e.g. @ai-sdk/openai).
2

Create the Streamable HTTP transport

Use StreamableHTTPClientTransport with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and use tools

Call mcpClient.tools() to auto-discover all Modusign tools. Pass them directly to generateText() or streamText() — no manual schema definitions needed.
4

Works with any model provider

Swap openai("gpt-4o") for any AI SDK provider — Anthropic, Google, Mistral. The MCP tools work identically across all supported models.

index.ts

import { experimental_createMCPClient as createMCPClient } from "ai";
import { StreamableHTTPClientTransport } from "@modelcontextprotocol/sdk/client/streamableHttp";
import { generateText } from "ai";
import { openai } from "@ai-sdk/openai";

const transport = new StreamableHTTPClientTransport(
  new URL("https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp")
);

const mcpClient = await createMCPClient({ transport });
const tools = await mcpClient.tools();

const { text } = await generateText({
  model: openai("gpt-4o"),
  tools,
  prompt: "List recent Modusign transactions",
});

console.log(text);
await mcpClient.close();
