How to Use the Camunda (BPMN Engine) MCP in Vercel AI SDK

Q: Can I complete a user task using Camunda (BPMN Engine) in Vercel AI SDK?

Yes, you use the completeusertask tool to send data back to the engine. Your Vercel AI SDK app captures the form values and pushes them to the backend.

Q: What happens if a process fails in Camunda (BPMN Engine) with Vercel AI SDK?

You can use searchincidents to find exactly where the failure occurred. Your agent then reports the issue back to the user interface.

Q: How is my BPMN process variable data handled by Camunda (BPMN Engine) and Vercel AI SDK?

Your process variables are retrieved using getvariable or searchvariables. This data travels over an encrypted HTTPS connection and is never stored on the Vercel AI SDK server itself.

Stream Camunda (BPMN Engine) process data directly into your Vercel AI SDK frontends for live, interactive UI updates.

Real-time process monitoring in Vercel AI SDK

Pipe live process status directly into your components using `get_process_instance` and `search_process_instances`. Your users see the state of their workflows move through the engine without waiting for a stale page refresh. This MCP Server feeds the data stream so your React or Next.js app renders task updates as they hit the server. You stop guessing if a process finished and start showing the actual current step.

Managing human tasks via Vercel AI SDK

Give your interface the ability to handle user interaction with `assign_user_task` and `complete_user_task`. Your frontend now acts as a full control panel for every pending action in the business logic. Users interact with `get_user_task_form` to see exactly what fields they need to fill out. You get a clean way to bridge the gap between complex backend logic and the browser.

Dynamic deployment and execution control

Push new BPMN definitions to the cluster on the fly using `deploy_resources`. When you need to change a workflow, the agent makes the call and confirms the deployment instantly. Trigger new work with `start_process_instance` based on user input or automated events. You keep the engine running exactly how you want it without leaving your codebase.

Setup guide

Set up Camunda (BPMN Engine) 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 Camunda (BPMN Engine) 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 Camunda (BPMN Engine) transactions",
});

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