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 join, through one secure, audited handshake.

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 join — whether you signed up on the service itself or arrived on an invitation. 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 granted to you — 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 access works

From your service to inside, in four steps.

You start on the service you already use: its signup page hands you to the Hub for one short, secure handshake. Deliberate invitations still work exactly as they always have. Either way the whole handshake is hosted by the Hub, so your credentials live in exactly one trusted place.

01 · START

You start in your service

Sign up on the service you're joining — brainattic.ai today. It hands you to the Hub through a single-use link, for the identity step alone. An operator's invitation opens the same door for staff accounts and for onboarding done by hand.

02 · VERIFY

Your address is confirmed

Continue with Google and your address is trusted from the start. Otherwise the Hub emails you a single-use link — an invitation, good for seven days, or a confirmation that follows your signup rather than holding it up.

03 · SECURE

You choose how to sign in

Choose a password on a page hosted by the Hub itself, or keep signing in with Google. Either credential opens the same account, 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 join.

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.
