Perplexity

Handling fact retrieval failures.

If one attempt to fetch a random fact fails, your workflow won't crash. You can set up automatic retries using the `get_random_fact()` tool. Mastra AI handles exponential backoff until it successfully pulls the trivia. This makes building complex content pipelines much safer because of its built-in error handling.

Targeted data fetching in workflows.

Need to ensure a specific piece of information is retrieved? Use `get_fact(id)` within your workflow. This gives you highly targeted data retrieval, which is crucial when multiple steps rely on one single fact. The process fits perfectly into conditional branching: if the first attempt fails, retry with this specific tool.

Mandatory daily content generation.

Set up a scheduled workflow that runs every day to grab `get_today_fact()`. This guarantees fresh, mandatory content without manual intervention. You can even specify the language for consistency. This is ideal for pipelines where daily updates are required, making failure handling critical.

Setup guide

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

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

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