Perplexity

Conditional screening with Mastra AI

Use `add_hr_packages` to build branching logic that triggers different screening levels based on job role. If a check flags an issue, the agent automatically pauses the workflow. This keeps your hiring pipeline compliant without manual oversight. You define the rules and the agent executes the checks.

Reliable background checks in Mastra AI

Leverage the built-in retry mechanisms to handle intermittent API hiccups when calling `list_hr_applicants`. Your agent ensures every applicant gets screened, even if the network blips. It tracks the state of every invite. You don't have to worry about missing a candidate in the queue.

Managed MCP Server workflows

This MCP Server integrates into your agents to handle human-in-the-loop approvals for `invite_hr_application`. The agent presents the data for your review before sending the invite. It puts you in control of the process. You approve the check and the agent finishes the job.

Setup guide

Set up Certn MCP in Mastra AI

Prerequisites

Node.js 18+ and a TypeScript project
@mastra/mcp + @mastra/core packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run npm install @mastra/mcp @mastra/core plus your preferred model provider (e.g. @ai-sdk/openai).
2

Configure the MCPClient
Create an MCPClient with your Vinkius endpoint as a URL object. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Discover and inject tools
Call mcpClient.listTools() and spread the result into your agent's tools object. All Certn tools become native Mastra tools.
4

Run with any model
Swap openai("gpt-4o") for any AI SDK-compatible provider. Call agent.generate() and the agent routes tool calls through MCP automatically.

agent.ts

import { MCPClient } from "@mastra/mcp";
import { Agent } from "@mastra/core/agent";
import { openai } from "@ai-sdk/openai";

const mcpClient = new MCPClient({
  id: "certn-mcp-client",
  servers: {
    "certn-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

const agent = new Agent({
  name: "Certn Agent",
  model: openai("gpt-4o"),
  instructions: "You have access to Certn tools.",
  tools: {
    ...(await mcpClient.listTools()),
  },
});

const result = await agent.generate(
  "List recent Certn transactions"
);
console.log(result.text);
