Automated bond valuation workflows

Trigger `calculate_bond_valuation` within your Mastra AI agent chains to automate your investment analysis. If a bond price hits a threshold, the agent acts on the result immediately. This setup allows for conditional logic based on YTM. You can build a workflow that alerts your team only when specific return criteria are met.

Multi-currency yield monitoring

Use `calculate_currency_equivalent_yield` to build agents that track global sovereign debt. You can set up retries if the data fetch fails, ensuring your records stay accurate. Your Mastra AI agent handles the conversion logic as a distinct step. This keeps your main business logic clean and focused on decision-making.

Inflation impact analysis

Integrate `calculate_inflation_adjusted_return` into your routine reporting tasks. The agent calculates the real return for various bonds and generates a summary for your review. It handles the heavy lifting of the Fisher equation. You just define the workflow, and the agent executes the calculation whenever new market data arrives.

Setup guide

Set up Treasury Return Calculator 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 Treasury Return Calculator 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: "treasury-return-calculator-mcp-client",
  servers: {
    "treasury-return-calculator-mcp": {
      url: new URL(
        "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
      ),
    },
  },
});

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

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