Manage customers, addresses, subscriptions, charges and orders on Recharge, the subscription/recurring-billing platform for Shopify and BigCommerce stores.
Recharge ships in the w6w first-party pack. It declares 29 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.
io.w6w.rechargeRecharge runs recurring billing for ecommerce stores — mostly Shopify, also BigCommerce and custom integrations — turning a one-time product into a subscription with its own billing schedule, retry logic and customer self-service.
This app covers the day-to-day operations a workflow needs around a subscription’s lifecycle: creating and updating customers and their shipping addresses, creating subscriptions and one-time purchases, rescheduling or cancelling a subscription’s next charge, and skipping, unskipping or refunding an individual charge. Reads cover customers, addresses, subscriptions, charges, orders, the product catalog, discounts, payment methods and webhooks.
Health checks track Recharge’s own status page (scoped to its API component specifically, not the Shopify/BigCommerce integrations the same page also tracks) alongside the store’s live rate-limit headroom.
Three routes to the same 29 actions. The Workflow tab is generated from Recharge's own manifest and carries its real ids, so it is copy-pasteable; the Code and CLI examples are the same call for any action on any app, so every app-specific value in them is a blank you fill in.
address-update Modify an existing address's fields. Only the fields provided are changed.
charge-get Retrieve one charge by its Recharge charge id. A processed charge older than 90 days may no longer be retrievable — see List Charges for details.
charge-list Return a list of charges. Processed charges older than 90 days are not returned by Recharge; see the description for details.
customer-create Create a customer in Recharge. Does not create the customer on any other connected platform.
customer-update Modify an existing customer's profile fields. Only the fields provided are changed.
payment-method-list Return a list of payment methods in the store, or for one customer.
subscription-set-next-charge-date Change the date a subscription's next charge is scheduled to run.
token-information-get Return the connected API token's own name, scopes, and (for an OAuth-app token) the client that generated it.
webhook-list List webhooks owned by this connection's token. A private (merchant) token sees every webhook on the store; an integration token sees only its own.
A workflow step names the app and the action, and the editor fills in the
connection when you pick one. This is the Step shape from the
workflow spec, carrying Recharge's real ids.

Every app-specific value here is a blank you have to fill in. An
app action is reached through the connection that authenticates it, so the
address is a connection id, not the app id — and connections belong to your account,
so a public page cannot know yours. Create one for Recharge, then fill in
the three blanks: conn_YOUR_CONNECTION_ID, the action key, and the
parameters that action declares. The call itself is real — the shape is transcribed
from the studio's own snippet builder, which prints the same kind of blanks — but
nothing in it is specific to Recharge. The Workflow tab is where this app's
real ids are.

One MCP endpoint exposes every app, function and workflow the caller is entitled to, as tools it can discover and run. Access is granted per team while we onboard.
One tool call{
"name": "w6w_invoke",
"arguments": {
"ref": "app:io.w6w.recharge#address-get",
"input": {
"addressId": "<addressId>"
}
}
}
Every tool names its target with a single ref. The
app: form above doesn't name a connection at all — the
host resolves which of the caller's Recharge connections to sign
with, and refuses rather than guesses when the answer is ambiguous.
The token is attached host-side, at the moment of the call. It is never a tool argument, never in the model's context, and never in a transcript — so a prompt injection has nothing to exfiltrate.
Tools are derived per end user from what that person has actually connected and is entitled to — not one shared bot identity carrying the union of everyone's access.
Multi-step work runs on the workflow engine and returns a run handle the agent can poll — retries, branching and state survive the conversation that started them.
Recharge's declared health checks are on the surface too, so an agent can tell "the vendor is down" from "your credential expired" before it burns a retry on either.
The MCP surface is part of the hosted platform. Recharge itself is MIT, and the runtime that executes it is source-available (FSL).
Recharge declares its own checks, so its health is a property of the app rather than something the host guesses at.
The 'Recharge API' component from status.getrecharge.com. The page also tracks Shopify and BigCommerce components Recharge integrates with — those are surfaced for context but never drive this check's own verdict.
