Perplexity

Automated payment audit chains

Chain multiple tools together to create complex compliance checks. Your agents use `list_datasets` to identify the right file, then `query_dataset` to extract specific payment triggers for review. If the initial query fails due to network jitter, Mastra AI automatically retries the operation. This ensures your audit pipeline completes without manual intervention.

Conditional multi-step verification

Implement branching logic based on payment thresholds. You define conditions where an agent uses `search_physicians` first, and if the profile is flagged, it proceeds to fetch detailed hospital records via `search_hospitals`. This allows you to automate the discovery process. You catch high-risk relationships by routing them through a predefined logic flow that handles standard compliance verification.

Scheduled bulk data synchronization

Trigger `download_dataset` on a schedule to maintain a local mirror of payment records. This keeps your agent's memory updated with the latest federal disclosures without hitting live API limits for every single check. Your workflows remain fast and consistent. By localizing the data, your agents perform deep analysis on large datasets while respecting the constraints of the remote source.

Setup guide

Set up HHS Open Payments 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 HHS Open Payments 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: "hhs-open-payments-mcp-client",
  servers: {
    "hhs-open-payments-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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