Automated member onboarding workflows in Mastra AI

This MCP Server lets you write workflows that trigger when a new user signs up, using `get_member` to pull their Memberstack profile and verify their status. If the profile is incomplete, the Mastra AI workflow branches to update their details. The Mastra AI agent can automatically inspect `list_custom_fields` to find missing registration data. If fields are empty, the Mastra workflow queues a notification sequence to prompt the user, keeping your Memberstack database clean without manual checks.

Resilient plan updates with Mastra AI workflows

When syncing subscription tiers, the Mastra AI agent calls `get_member_plans` to check what a user has purchased. If the Memberstack API rate limit is hit, Mastra automatically pauses and retries the call. You can build conditional paths based on the results of `list_plans`. If a member's Memberstack plan doesn't match their current usage, the Mastra AI workflow uses `get_plan` to fetch pricing and flags the account for your billing team.

Bulk member audits and coupon validation

Your Mastra AI agent can run scheduled workflows that call `list_members` to scan your entire Memberstack user base. It cross-references active accounts against active promotions using `list_promotions` to flag expired deals. The Mastra AI workflow can also pull `list_coupons` to verify that active Memberstack discounts are applied correctly. If an anomaly is found, the Mastra AI agent logs the discrepancy directly into your internal systems.

Setup guide

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

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

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

Common questions about Memberstack MCP in Mastra AI

Instantiate the client using the Mastra MCP class and point it to your Vinkius server URL. Once configured, you can spread the tools directly into your Mastra agent's tool array.

Yes. Mastra workflows can execute conditional steps that query custom fields using `list_custom_fields` and use that data to route users to specific onboarding steps.

Mastra has built-in retry mechanisms with exponential backoff. If calls to `list_members` or `search_members` run into rate limits, the workflow engine pauses and retries the request automatically.

Yes. Mastra AI supports human-in-the-loop approvals, meaning the agent can query `get_plan` but will wait for manual sign-off before executing subsequent billing actions.

Yes, it is. All API tokens and member details are transmitted over TLS directly to Memberstack. Vinkius executes the server in a zero-trust, ephemeral sandbox that destroys the runtime state immediately after processing your workflow calls.
