Identity Provider · Authorization Server

One identity for every Finite app.

FSS MCP Hub is the single sign-on and authorization core behind Finite Software Systems' growing family of products — beginning with brainattic.ai. One account opens every app you're invited to, through one secure, audited handshake.

one core · many apps

the single IdP

Sign in once. The whole family opens up.

Finite Software Systems builds a range of products. They share one front door: FSS MCP Hub issues and checks every credential, so you carry a single identity from app to app — never a new password, never a separate account to manage.

Sign in once

One account from Finite Software Systems opens every app you're invited to. No new password to set per product, no separate logins to keep track of.

Scoped to exactly you

Your access is confined to your own workspace and the apps you've been invited to — and nothing beyond it. The Hub pins each account to its place.

Every action accounted for

Because authorization runs through one core, access stays consistent and traceable across the family. Each grant and sign-in is recorded.

how invitations work

From invite to inside, in four steps.

You don't sign up — you're invited. The whole handshake is hosted by the Hub, so your credentials live in exactly one trusted place.

01 · INVITE

You're invited

A workspace admin issues an invitation for one app and one team. Nobody self-registers — every account starts from a deliberate invite.

02 · DELIVER

A link arrives

The Hub emails you a single-use link that's good for seven days. Open it to begin — no account exists until you do.

03 · ACTIVATE

You set a password

On a page hosted by the Hub itself, you choose a password. Your account is created and pinned to exactly your workspace — nothing more.

04 · CONNECT

You're inside

You land signed-in, straight in your app. From then on, that same identity opens every other Finite app you're invited to.

the mark

A processor for identity.

The logo is a single chip with FSS MCP HUB etched into its face, and copper traces escaping its edges like routing fanning off a processor on a board.

One core issues the credentials. The traces carry that identity outward — to every app in the family.
