A working SaaS you build on: accounts, organizations, billing, an API and an MCP server, with a placeholder resource called items. Replace the items with what your product does.

What does the free plan include?

1,000 credits every month, every feature, and no card. Move to a plan when you need more.

What does a call cost?

Creating or editing an item costs 1 credit. Reading costs 0. Your usage page shows every call and what it cost.

In a Cloudflare D1 database and an R2 bucket, in the European Union. You can export your items at any time from the settings.

Can an AI agent use it?

Yes. The MCP server lets an agent sign in through OAuth and act with the role of the person who connected it. An agent that cannot open a browser can use an API key with the mcp scope.

In the box

Everything a SaaS needs before its first feature

Each part is wired to the others and tested, so you start on your product on day one.

Accounts

Sign-up and sign-in

Better Auth with email and password, magic links, GitHub and Google.

Two-factor authentication with backup codes
Email verification and password reset
Turnstile on every public form

Billing

Plans and credits

Stripe Checkout and the customer portal, with the prices kept in code.

Monthly and yearly plans
Credit packs for the busy months
Invoices, grace periods and dunning notices

API

A public API with keys

A REST API under /v1, with an OpenAPI document and errors that say what to do.

Keys scoped to read, write or the MCP server
A write costs 1 credit, and retries are idempotent
Rate limits per key and per organization

AI agents

An MCP server

Agents connect through OAuth and act with the role of the member who allowed them.

Works with Claude, Cursor and VS Code
A call log for every tool call
One switch to stop every agent

Teams

Organizations and roles

Invite members as owner, admin, developer or billing, each with the access the API enforces.

Invitations by email
An audit log of every change
Usage by day and by key, with a CSV export

Guard

Fraud and moderation

Sign-ups, sign-ins and what users write are checked by openshield, and what it holds waits for a review.

Fake sign-ups refused or challenged
Texts and files moderated before they are stored
Off until you add an API key
