How to Use the ExchangeRate-API MCP in Mastra AI

Q: Does Mastra AI support human approval for ExchangeRate-API calls?

Yes. Enable requireToolApproval in your configuration. You can pause the workflow until you verify the currency conversion manually.

Q: Can I use ExchangeRate-API with Mastra AI branching logic?

You can branch based on the output of getlatestrates. If the rate crosses a threshold, trigger a specific workflow path.

Automated rate retrieval in Mastra AI

Trigger `get_latest_rates` as a step inside your agentic workflow. If the network blips, Mastra handles the retry logic automatically. This keeps your currency data flow stable during high-traffic periods. Your agents stay focused on decision-making.

Multi-step currency conversion

Chain `convert_currency_pair` with other logic to automate payments or invoicing. The agent calculates the rate before moving to the next step. It handles the conversion logic entirely inside the workflow execution. You define the sequence, and the agent executes it.

Historical data analysis for agents

Give your agents access to `get_historical_rates` to spot trends. They can audit past performance before suggesting a new transaction. This adds a layer of logic to your automated operations. Your agent makes informed choices based on the data retrieved.

Setup guide

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

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

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