Automated candidate pipelines in Mastra AI

Chain your hiring steps together using `list_applications` and `get_application`. If a step fails, the framework automatically retries to ensure no candidate slips through the cracks. This creates a predictable flow for your recruiting team. You define the logic, and the tools handle the data retrieval.

Conditional hiring logic for your agents

Use `list_jobs` to decide which hiring workflow to trigger next. If a job is marked as urgent, your agent can prioritize those applications automatically. It handles the branching logic based on real-time data. You spend less time managing the process and more time interviewing.

Manage your recruiting workspace

Query `list_departments` and `list_locations` to organize your recruitment data. This allows your agents to route tasks to the correct hiring manager automatically. Everything stays structured according to your business needs. You get a clear view of your entire organization structure.

Setup guide

Set up Join 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 Join 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: "join-mcp-client",
  servers: {
    "join-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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