Perplexity

Automated Compliance Monitoring

Create agent workflows that use `search_federal_documents` to scan for new rules daily. If the search turns up a hit, your Mastra AI agent can trigger a follow-up task automatically. You can set up retries if the network blips. This keeps your compliance tracking running even when external services are flaky.

Reliable API Status Verification

Use `check_api_status` as the first step in your agentic workflow. If the system reports downtime, you can route the process to a standby task or notify your engineering team immediately. This prevents your agents from guessing why a search failed. You handle the error logic explicitly within your Mastra AI code.

Structured Agency Data Retrieval

Fetch a list of active government entities with `list_federal_agencies`. You can use this to dynamically update which agencies your Mastra AI agents monitor during their cycles. It ensures your workflows are always targeting the right source. You spend less time updating hardcoded lists and more time processing the actual data.

Setup guide

Set up Federal Register API 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 Federal Register API 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: "federal-register-api-mcp-client",
  servers: {
    "federal-register-api-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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

Common questions about Federal Register API MCP in Mastra AI

Mastra AI supports automatic retries. You define the backoff strategy in your workflow, and the MCP server will re-attempt the `search_federal_documents` call if it hits a temporary error.

Yes. Use the requireToolApproval setting. This lets a human review the search parameters before the agent actually fires the request to the Federal Register API.

You add the tools to your agent definition. Mastra AI detects them, and you can then sequence them alongside your other logic, like database writes or email alerts.

Absolutely. You can take the output from `search_federal_documents` and pass it into `get_federal_document_details` within the same agent step to get full text.

The server only touches public regulatory information. Your internal business logic remains separate, and all communication is encrypted through the Vinkius ephemeral tunnel.
