Subscription Renewal Processor

Automates subscription renewals by sending advance notices, processing payments, handling failed payments with retry logic, and updating customer records. Reduces involuntary churn.

Toolkits Needed

You'll need access to these toolkits in your Arcade MCP Gateway:

Stripe
Hubspot
Gmail

Setup Guide

1

Sign up for Arcade

Create a free Arcade account to get access to MCP Gateway.

Create Arcade Account →
2

Create a new MCP Gateway

Navigate to MCP Gateway page in Arcade, then click Create MCP Gateway.

Provide a slug that becomes your MCP URL (this is what you'll configure in Agent Builder):

Example: If you choose slug my-agent, your MCP URL will be:
https://api.arcade.dev/mcp/my-agent
3

Select the specific tools you need

Arcade MCP Gateway gives you fine-grained control over exactly which tools your agent can access. Select these specific tools from the toolkits:

Stripe.ListCustomers
Stripe.ListInvoices
Hubspot.ListContacts
Hubspot.CreateContact
Hubspot.UpdateContact
Gmail.ListEmails
Gmail.SendEmail
Gmail.ReplyToEmail
Choose your tools in Arcade MCP Gateway

Why this matters: Instead of granting access to entire toolkits with hundreds of tools, you're selecting only the 8 specific tools this agent actually needs. This precision reduces risk and keeps your agent focused.
