About

Baremetrics ships in the w6w first-party pack. It declares 30 actions, 2 health checks, and the host runs its code in a sandbox that never sees the credential.

Overview

Baremetrics turns subscription billing data into the metrics a SaaS business steers by: MRR, ARR, churn, LTV, trials and more. This app reads those metrics over any date range, broken out by plan or down to the customers behind a number, and lists the customers, plans, subscriptions, charges and refunds in each connected source.

For teams that bill outside Stripe, Recurly or Braintree, it can also write to the Baremetrics API source: create, update and delete customers, plans, subscriptions and charges. Data that comes from a payment-provider source is read-only, as Baremetrics itself enforces.

Health checks verify the API key and track the hourly request allowance from Baremetrics’ own rate-limit headers.

Build with Baremetrics

Three routes to the same 30 actions. The Workflow tab is generated from Baremetrics'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.

Get Account

account-get

Fetch the account: id, default currency, company name and creation time.

List Annotations

annotations-list

List the annotations shown on the account's graphs.

Create Charge

charge-create

Record a charge in the Baremetrics API source.

Delete Charge

charge-delete

Delete a charge that was added through the API.

Get Charge

charge-get

Fetch one charge by oid.

List Charges

charge-list

List charges in a source, optionally by time range, customer or subscription.

Create Customer

customer-create

Create a customer in the Baremetrics API source. Only oid is required.

Delete Customer

customer-delete

Delete a customer that was added through the API.

List Customer Events

customer-events-list

List the events recorded for one customer.

Get Customer

customer-get

Fetch one customer by its oid.

List Customers

customer-list

Update Customer

customer-update

Update a customer's name, email, notes or created time. Only customers added through the API can be modified.

List Goals

goals-list

List the account's revenue goals.

List Metric Customers

metric-customers

The customers behind one metric over a date range.

Get Metric

metric-get

Daily values of one metric over a date range, optionally compared with an earlier period.

Get Metric Plan Breakout

metric-plans

One metric broken out by plan over a date range.

Get Metrics Summary

metrics-summary

Daily summary of every core metric (MRR, ARR, customers, churn, LTV and more) over a date range.

Create Plan

plan-create

Create a plan in the Baremetrics API source.

Delete Plan

plan-delete

Delete a plan that was added through the API.

Get Plan

plan-get

Fetch one plan by oid.

List Plans

plan-list

List plans in a source.

Update Plan

plan-update

Rename a plan. The name is the only field the vendor allows to change.

List Refunds

refund-list

List refunds in a source, optionally by time range.

List Sources

sources-list

List the sources (payment providers and the Baremetrics API source) on the account. Every source-scoped action needs one of these ids.

Cancel Subscription

subscription-cancel

Cancel a subscription at a given time.

Create Subscription

subscription-create

Create a subscription in the Baremetrics API source.

Delete Subscription

subscription-delete

Delete a subscription that was added through the API.

Get Subscription

subscription-get

Fetch one subscription by oid.

List Subscriptions

subscription-list

List subscriptions in a source, optionally for one customer.

Update Subscription

subscription-update

Change a subscription's plan, quantity, discount or add-ons.

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 Baremetrics's real ids.

+25 more actions available

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 Baremetrics, 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 Baremetrics. The Workflow tab is where this app's real ids are.

Install
npm install @w6w/sdk
yarn add @w6w/sdk
pnpm add @w6w/sdk
deno add npm:@w6w/sdk
Code
import { W6wClient, isActionRun } from "@w6w/sdk";

// Reads W6W_BASE_URL and W6W_TOKEN from the environment when omitted.
const client = new W6wClient();

const envelope = await client.run({
  urn: "conn_YOUR_CONNECTION_ID",
  action: "charge-create",
  payload: {
    source_id: "<value>",
    oid: "<value>",
    amount: "<value>",
    currency: "<value>",
    customer_oid: "<value>",
    // created: "<value>",
    // status: "<value>",
    // fee: "<value>",
    // subscription_oid: "<value>",
  },
});

if (isActionRun(envelope)) console.log(envelope.value);
Install the CLI
npm install -g @w6w/cli

w6w run conn_YOUR_CONNECTION_ID --action charge-create --payload '{"source_id":"<value>","oid":"<value>","amount":"<value>","currency":"<value>","customer_oid":"<value>"}'

Give an AI agent Baremetrics — without giving it Baremetrics's credentials. 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.baremetrics#charge-create",
    "input": {
      "source_id": "<source_id>",
      "oid": "<oid>",
      "amount": "<amount>"
    }
  }
}

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 Baremetrics connections to sign with, and refuses rather than guesses when the answer is ambiguous.

What the agent gets

Credentials it can't read

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.

A tool surface scoped to the caller

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.

A durable workflow in one call

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.

Health-aware discovery

Baremetrics'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. Baremetrics itself is MIT, and the runtime that executes it is source-available (FSL).

Request MCP access

Health checks

Baremetrics declares its own checks, so its health is a property of the app rather than something the host guesses at.
