Build resilient financial workflows

Retail investors need accurate yield data before making decisions. When you build automated financial advisors, you need reliable math that integrates perfectly with conditional logic. This MCP provides the exact numbers required for complex routing. Your agent can run `calculate_cd_yield` to determine the exact return on a locked deposit. If the yield falls below a specific threshold, Mastra AI can automatically branch the workflow to suggest alternative investment strategies. The math is concrete and actionable.

Compare alternatives automatically

Locking up capital carries an opportunity cost. Your workflow needs to evaluate liquid alternatives automatically to provide responsible advice. This tool supplies the baseline data for those comparisons. Use `fetch_market_benchmarks` to grab hardcoded rates for high-yield savings and money market funds. Mastra AI can use these figures to trigger automated alerts when liquid rates outpace locked terms. You build the logic and this catalog supplies the data.

Generate full comparison matrices in Mastra AI

Presenting a single number rarely helps an investor. They need side-by-side scenarios. You can configure your agent to compile these scenarios automatically during a scheduled workflow execution. Call `generate_investment_comparison` to produce a high-level view of locked versus liquid returns. Your agent processes this matrix and routes it to the user via email or a notification system. The entire sequence runs autonomously based on your predefined rules.

Setup guide

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

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

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

Common questions about CD Return Calculator MCP in Mastra AI

Install the latest Mastra package and instantiate the client with the Vinkius URL. List the available tools and spread them directly into your agent configuration. The framework handles the transport layer automatically.

Yes. The framework includes built-in exponential backoff for all tool calls. If a network timeout occurs during a calculation, your agent will retry the operation automatically before failing the workflow.

The framework parses the JSON response from the tool and stores it in the workflow state. You can reference those specific yield figures in subsequent steps or conditional branches.

Vinkius hosts over 4,000 tools in one catalog. You connect your agent once and immediately access this calculator alongside thousands of other utilities. It saves you weeks of custom development.

The calculator only processes anonymous numbers like principal balances and interest rates. It requires zero personal identification or account linkage. Vinkius processes the mathematical request and immediately discards the inputs.
