How to Use the DevSkiller MCP in Vercel AI SDK

Q: How does Vercel AI SDK render the DevSkiller candidate profiles?

The SDK streams tool calls like getcandidateprofile directly to the UI using helper components. This lets your React application render structured candidate data as soon as the API responds.

Pipe live DevSkiller test scores and candidate updates straight into your Next.js app using the Vercel AI SDK.

Live Candidate Screening in the Vercel AI SDK UI

This DevSkiller MCP Server exposes real-time screening tools directly to your edge-rendered frontend. Your AI client invokes `list_assessment_candidates` and streams the active pipeline straight into a React table without making the recruiter stare at a blank loading screen. When you need details, the SDK triggers `get_candidate_profile` on the edge, pulling candidate history into the UI instantly. You get immediate visual updates as your team filters applicants, making the screening process feel fast and responsive.

Instant Test Dispatch and Progress Tracking

Sending test invitations happens instantly when your AI client triggers `invite_candidate_to_test` through the DevSkiller MCP Server. The UI updates the moment the invitation goes out, showing the change in status without requiring a manual page refresh. To keep recruiters updated, the agent uses `list_recently_sent_invitations` to display a live feed of active assessments. This setup ensures that your team sees exactly who received a test in the last 24 hours without leaving their main dashboard.

Interactive Score Filtering and Reports

Your Vercel AI SDK agent uses `list_high_score_candidates` to filter top performers and render their scores live. It bypasses the need for manual CSV exports by feeding raw assessment metrics straight into your frontend component. Clicking a high scorer prompts the agent to call `get_candidate_assessment_report` and render the full breakdown. Recruiters can review specific coding skills and test metrics on the fly while the AI handles the background data fetching.

Setup guide

Set up DevSkiller 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 DevSkiller 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 DevSkiller transactions",
});

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

Common questions about DevSkiller MCP in Vercel AI SDK

You initialize the MCP client in your route handler and pass the tools to `streamText`. Use the HTTP transport to keep the connection lightweight and fast on the edge. Remember to call `mcpClient.close()` to prevent memory leaks in your serverless environment.

Yes, you can chain calls in your server action or API route. The agent can search for an applicant using `search_candidates_by_identity` and then immediately trigger `invite_candidate_to_test` based on the search results.

The SDK streams tool calls like `get_candidate_profile` directly to the UI using helper components. This lets your React application render structured candidate data as soon as the API responds.

The SDK catches the error from the MCP server and passes it to the client-side error boundary. You can handle this gracefully in your UI by displaying a fallback message while preserving the rest of the conversation history.

All candidate personal identifiers and test scores pass through Vinkius's isolated sandbox, which never writes this data to disk. The connection between your app and the DevSkiller API uses encrypted HTTPS endpoints, ensuring candidate details remain completely confidential.
