How to Use the Duffel MCP in Mastra AI

Q: Can I require human approval before Mastra AI executes a Duffel booking?

Absolutely. You can mark the createorder tool as requiring manual validation, pausing the workflow until an operator reviews the flight details.

Q: How do I track payments for flight holds in Duffel using Mastra AI?

Use createpayment to authorize funds for a held order. The agent can monitor the payment state with getpayment to confirm the booking is finalized.

Q: What happens if a hotel rate expires mid-workflow?

The fetchstayrates tool will return an error, prompting your agent to run searchstays again to find an alternative room.

Build resilient, self-healing flight booking workflows in Mastra AI using automated retries and conditional logic.

Perplexity

Multi-step booking workflows

`create_order` executes the final booking through the MCP server once your workflow confirms payment details. If the carrier API times out, Mastra AI uses its built-in engine to retry the call using exponential backoff. You can set up conditional branches that handle failures gracefully. For example, if a booking fails, the workflow can trigger `cancel_order` to clean up pending holds and alert your team.

Programmatic stay booking with an MCP Server

`search_stays` queries hotel inventories based on location, dates, and guest count. The resulting data feed goes straight into your agent's decision loop. From there, `quote_stay` locks in the rate for a specific room before final payment. This ensures your workflow never books a room that just changed prices or sold out.

Real-time updates via travel webhooks

`create_webhook` registers endpoints to listen for flight delays, schedule changes, or cancellation events directly from carriers. Your agent can monitor these incoming events to trigger automatic rebooking sequences. When an event fires, `list_webhook_events` helps verify the payload authenticity. This keeps your system synced with airline operational changes without constantly polling their APIs.

Setup guide

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

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

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

Common questions about Duffel MCP in Mastra AI

You configure the Mastra workflow engine to throttle outgoing requests. The framework queues calls to tools like `list_offers` so you don't hit carrier-imposed limits.

Absolutely. You can mark the `create_order` tool as requiring manual validation, pausing the workflow until an operator reviews the flight details.

Use `create_payment` to authorize funds for a held order. The agent can monitor the payment state with `get_payment` to confirm the booking is finalized.

The `fetch_stay_rates` tool will return an error, prompting your agent to run `search_stays` again to find an alternative room.

Payment card data never rests on Vinkius servers. The MCP tool sends the billing details directly to the PCI-compliant API gateway, keeping your local database out of scope for compliance audits.
