How to Use the Cheddar MCP in Mastra AI

Q: How do I register Cheddar tools inside a Mastra AI agent?

Install @mastra/mcp and initialize the client with your Vinkius URL. You then fetch the tools from the MCP Server and spread them into your Mastra agent's tool configuration.

Q: Can Mastra AI handle human approval before modifying Cheddar plans?

Yes, you can configure Mastra's requireToolApproval middleware for sensitive operations. Your agent will pause and wait for a manual confirmation before executing listcheddarplans or changing a customer's setup.

Multi-Step Billing Retries in Mastra AI

The `list_cheddar_invoices` tool checks the payment status of recent customer statements to identify failed transactions. Mastra AI uses this billing data to trigger automated retry workflows with exponential backoff when a Cheddar invoice remains unpaid. If a Cheddar payment fails, your Mastra AI agent automatically checks for active discounts before retrying. This workflow runs in the background without requiring manual intervention from your billing team.

Automated Promotion Management

The `list_cheddar_promotions` tool retrieves all active coupons and discount codes currently configured in your account. Your Mastra AI agent evaluates these Cheddar promotions against customer accounts to apply discounts during retention workflows. When a customer threatens to churn, the Mastra AI agent runs a conditional branch to offer an active Cheddar coupon. The system applies the discount instantly to keep the customer subscribed.

Usage-Based Charge Workflows

The `add_cheddar_charge` tool posts new usage records directly to a customer's pending invoice. Integrating this tool with a Mastra AI workflow lets you automate complex metered billing cycles based on Cheddar system events. The MCP Server processes these Cheddar charges as your Mastra AI agent monitors system resources. This setup ensures that your usage tracking and billing remain perfectly aligned.

Setup guide

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

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

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