How to Use the Yousign MCP in Vercel AI SDK

Q: How do I list all signature requests with Yousign and Vercel AI SDK?

Just call listsignaturerequests. This returns a complete list of all current document signing processes associated with the account. You can then stream this data directly to your client-side components.

Q: Can I check signature status using Yousign and Vercel AI SDK?

Yes, you use getsignaturerequest. This function fetches the current state of a specific request. Because this data streams, your UI updates instantly when the document moves from 'pending' to 'completed'.

Q: What kind of metadata can I pass with Yousign and Vercel AI SDK?

When adding documents via adddocumenttorequest, you provide metadata. This allows your application logic—running on the client side—to track context beyond just the file itself, making the process more reliable.

Q: Does this MCP Server handle contact management for Yousign and Vercel AI SDK?

Yep. You can manage contacts by calling createyousigncontact or getting a full list using listyousigncontacts. It keeps your address book synchronized with the signing platform.

Check Request Status Live via MCP Server

You can call `get_signature_request` and stream the resulting status directly into React or Next.js components. This means users see the signature progress updating in real-time, not after a loading spinner. It's perfect for building user-facing products where knowing the current state—whether it’s pending or completed—is critical.

Manage Signers and Documents Dynamically

Need to adjust who signs? You can first call `list_signature_requests` to find a draft, then use `add_signer_to_request` to add new participants. You'll also pass metadata info when calling `add_document_to_request`, giving your frontend granular control. This flow lets you build sophisticated signing journeys where the UI updates instantly as changes are applied.

Retrieve Evidence and Audit Trails

After a document is signed, users need proof. Your AI client can call `get_audit_trail_link` to pull the evidence file link in real time. You'll also get account context using `get_workspace_details`. These functions give your application the immediate data it needs to display compliance information right where the user is looking.

Setup guide

Set up Yousign 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 Yousign 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 Yousign transactions",
});

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