How to Use the HackerOne MCP in Mastra AI

Q: How does Mastra AI handle rate limits when querying HackerOne?

The Mastra AI framework manages rate limits on calls like listreports or getreport by applying exponential backoff to HackerOne API requests. This prevents your workflows from breaking during high-traffic bug disclosures.

Q: Can I require human confirmation in Mastra AI before executing a HackerOne state change?

Yes, you can set requireToolApproval on the Mastra AI agent when calling the HackerOne changereportstate tool. This halts the workflow and sends a notification to your team, waiting for a manual click before updating the ticket.

Q: How do I register the HackerOne MCP Server tools in my Mastra AI agent?

Install @mastra/mcp and instantiate the MCP client using the Vinkius server URL to expose HackerOne tools to your Mastra AI agent. You then spread these tools directly into your agent's configuration object.

Q: Can my agent monitor multiple programs at the same time?

Yes, by calling listprograms and getprogram, your agent can discover and monitor every active security scope you manage. The workflow engine can loop through these programs sequentially to aggregate open vulnerabilities.

Automate HackerOne Triage Workflows with Mastra AI

The `list_reports` tool feeds raw HackerOne bug submissions directly into Mastra AI workflow pipelines for automated initial classification. Our framework evaluates the severity of the incoming HackerOne report and determines whether to escalate it immediately.

Resilient Bounty Payouts with Retries

The `award_bounty` tool executes financial transactions on HackerOne with the safety net of Mastra AI's built-in exponential backoff engine. If the HackerOne API experiences a temporary rate limit, the Mastra AI workflow automatically retries the payout.

Multi-Step Asset Auditing via MCP Server

The `list_assets` tool pulls your registered scope from HackerOne to cross-reference incoming bug reports in Mastra AI. Mastra AI can run a conditional branch to check if the reported HackerOne endpoint actually belongs to your official attack surface.

Setup guide

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

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

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