How to Use the FastSpring MCP in Mastra AI

Q: Can I require admin approval before Mastra AI cancels a FastSpring subscription?

Yes, you can use Mastra AI's requireToolApproval feature on the cancelsubscription tool. This ensures your autonomous Mastra AI agent cannot terminate a customer's FastSpring plan without an explicit human sign-off.

Q: How do I sync FastSpring customer profiles with my CRM using Mastra AI?

Create a Mastra AI workflow that uses listaccounts to scan for new profiles, fetches details via getaccountdetails, and then pushes updates back using updateaccountinfo when CRM events occur. The entire FastSpring process runs through our secure MCP Server.

Q: Does Mastra AI support secure FastSpring customer login generation?

Yes, your Mastra AI agent can call generateauthlink to create secure FastSpring customer portal links. Mastra AI can then pass this link to your email or chat steps to guide users directly to their billing settings.

Automated Subscription Churn Recovery

Build automated Mastra AI workflows that handle failed FastSpring payments and churn risks without human intervention. Mastra AI uses the `cancel_subscription` and `get_subscription_details` tools to detect failing FastSpring accounts and trigger your custom TypeScript retention paths. You can write step-by-step Mastra AI logic that checks `charge_managed_subscription` rules before executing a FastSpring cancellation. If the FastSpring API rate limits you, Mastra's built-in exponential backoff ensures this MCP Server call retries until it succeeds.

Resilient Account Sync Pipelines

Keep your CRM and FastSpring payment gateways perfectly aligned using Mastra AI's TypeScript workflows. The Mastra AI framework coordinates `list_accounts` with `get_account_details` to search for FastSpring discrepancies and update records using `update_account_info` automatically. This MCP integration means you do not have to write fragile cron jobs to sync FastSpring customer data in Mastra AI. If a sync step fails, Mastra AI isolates the failure and retries the specific FastSpring update without crashing the entire pipeline.

Safe Plan Upgrades with Approval Gates

Manage complex FastSpring pricing tier changes safely by putting Mastra AI approval gates on sensitive billing tools. Use `update_subscription_plan` alongside `list_catalog_products` to propose FastSpring subscription upgrades to high-value clients. Mastra AI holds the execution of `update_subscription_plan` until an admin approves the FastSpring change via your workflow portal. This prevents your autonomous Mastra agents from making unauthorized or incorrect billing changes to your FastSpring catalog plans.

Setup guide

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

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

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

Common questions about FastSpring MCP in Mastra AI

Mastra AI uses its built-in workflow engine to automatically retry failed calls to `charge_managed_subscription`. If a network hiccup or rate limit occurs during a FastSpring payment check, the Mastra AI framework backs off and retries the tool execution without failing the entire workflow.

Yes, you can use Mastra AI's `requireToolApproval` feature on the `cancel_subscription` tool. This ensures your autonomous Mastra AI agent cannot terminate a customer's FastSpring plan without an explicit human sign-off.

Create a Mastra AI workflow that uses `list_accounts` to scan for new profiles, fetches details via `get_account_details`, and then pushes updates back using `update_account_info` when CRM events occur. The entire FastSpring process runs through our secure MCP Server.

Yes, your Mastra AI agent can call `generate_auth_link` to create secure FastSpring customer portal links. Mastra AI can then pass this link to your email or chat steps to guide users directly to their billing settings.

The MCP Server runs inside a secure sandbox where only specific, non-PCI FastSpring customer metadata and subscription properties are accessed. Mastra AI never handles raw credit card information, keeping your FastSpring customer profiles and billing history isolated and safe.
