Fail-safe business day math in Mastra AI

The `business_deadline_tool` calculates deadlines on the fly by adding business days to a start date. This MCP integrates with your workflows to automatically skip weekends and holidays, ensuring your automated retries and billing loops execute on valid workdays. If a step fails, Mastra AI uses its built-in backoff engine to retry the calculation. You do not have to write custom loop logic or error handlers to keep your schedules accurate.

Clean calendar day offsets

The `calendar_deadline_tool` calculates standard calendar day offsets for your scheduling needs. It makes it easy to set up conditional branching in your workflows, like calculating a three-day grace period before sending an alert. This setup runs entirely on Vinkius, which means your serverless deployments stay fast and unburdened. You get reliable date math without configuring local timezone databases.

Dynamic holiday registry lookups

The `holiday_registry_tool` fetches regional holiday data to keep your schedules accurate. This prevents your workflows from triggering customer-facing notifications during national holidays. Connecting this MCP to Mastra AI takes a single configuration block. Once connected, your agents can coordinate with any of the other 4,000 tools available on the Vinkius catalog.

Setup guide

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

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

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