How to Use the Eversign (Cloud Electronic Signature) MCP in Vercel AI SDK

Q: How do I connect the Eversign (Cloud Electronic Signature) MCP Server to my Vercel AI SDK project?

Install @ai-sdk/mcp and create an HTTP client pointing to your Vinkius endpoint. This connects the server to your app. Pass the tools from the client directly into your text generation function.

Q: Can I use Eversign (Cloud Electronic Signature) templates with the Vercel AI SDK?

Yes, you can. The createdocument tool lets your agent specify template IDs and pre-fill signer fields dynamically.

Stream Eversign document workflows directly into your Next.js or React UI using the Vercel AI SDK and this MCP Server.

Live document generation in your frontend

`create_document` lets your Vercel AI SDK agent build and send electronic signature requests directly from your React or Next.js UI. Instead of making users wait for an API response, your frontend displays the document generation steps in real-time. You get immediate UI updates as the contract is compiled. This setup runs on Edge Functions, keeping your signature workflows fast and responsive without cold starts.

Multi-tenant business context mapping

`list_businesses` pulls all active business profiles associated with your Eversign account. Your AI client needs this tool to route documents to the correct legal entity dynamically. Passing this business directory directly to your Vercel AI SDK client ensures correct ID matching. No hardcoding or manual mapping is required when switching between different business units.

Instant template deployment via Vercel AI SDK

`create_document` also handles template generation and deployment for recurring contract types. Your agent can trigger pre-approved templates instantly based on user prompts. This MCP Server integration handles the heavy lifting of payload formatting. Your users watch their signing links appear live on screen as the Vercel AI SDK streams the output.

Setup guide

Set up Eversign (Cloud Electronic Signature) 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 Eversign (Cloud Electronic Signature) 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 Eversign (Cloud Electronic Signature) transactions",
});

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