How to Use the Ninehire MCP in Mastra AI

Q: How do I register the Ninehire tools inside a Mastra AI agent?

Install @mastra/mcp and instantiate the client pointing to your Vinkius MCP Server URL. Call mcpClient.listTools() and spread them directly into your agent's tools configuration array.

Q: Can Mastra AI handle human-in-the-loop approvals before updating Ninehire data?

Yes, you can enable requireToolApproval on your Mastra agent. This pauses the execution whenever the agent attempts to run a state-changing tool like registernewapplicant.

Q: How is my webhook and hiring team data protected when using Mastra AI?

Your webhook configurations from listconfiguredwebhooks and company structures from listhiringteams are processed inside a secure, ephemeral V8 isolate. Every transaction is completely sandboxed, ensuring no setup details leak to external networks.

Build resilient hiring pipelines in Mastra AI

Recruitment workflows break when APIs hiccup, but this integration keeps things moving. By registering this MCP Server with your Mastra agent, you can build multi-step pipelines that automatically retry `register_new_applicant` if a network blip occurs. Use Mastra's workflow engine to handle conditional branching when candidates apply. For instance, if `register_new_applicant` succeeds, automatically trigger `list_hiring_teams` to route the applicant profile to the right department.

Automate applicant screening with this MCP Server

Stop manually sorting through hundreds of resumes. This MCP Server lets your Mastra agent fetch candidate details using `get_applicant_profile` and run them through automated screening steps. You can set up workflows that branch based on evaluations. If `list_candidate_evaluations` returns a high score, the agent automatically triggers a webhook notification; otherwise, it archives the profile.

Manage active recruitment webhooks on any cloud

Deploy your recruitment agents to any cloud provider with a single command. Your Mastra AI agents can monitor and manage active integrations using the `list_configured_webhooks` tool to ensure your event pipelines stay healthy. If a webhook endpoint fails, Mastra's built-in retry logic with exponential backoff kicks in. The agent can double-check the API status using `check_api_health` before attempting to re-register the failing webhook.

Setup guide

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

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

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

Yes, you can enable `requireToolApproval` on your Mastra agent. This pauses the execution whenever the agent attempts to run a state-changing tool like `register_new_applicant`.

Mastra automatically detects the transport type, whether it is Streamable HTTP or SSE. You just supply the Vinkius endpoint URL, and the framework handles the communication protocols under the hood.

Mastra's workflow engine catches the failure and applies exponential backoff retries. The agent can also run `check_api_health` via the MCP gateway to verify if the service is online before retrying.
