Perstantia

Connect your AI

Perstantia is a remote MCP server. Add the address below to any MCP-capable client and your own AI reads and writes your record as you.

What your AI is being connected to

  1. Your future body, every week, from your own photos.

    Today · Draw a projection picture (AI, in the app)

  2. Studio progress pictures, automatically.

    Progress · Take a photoshoot — front, side and back, guided

  3. Log food from a photo and your notes together, or either on its own.

    Record · Estimate a meal from your description or a photograph (AI, in the app)

  4. A workout that survives your pocket, with the Watch counting rest.

    Workouts · Confirm a set from your Watch, adjusting reps or weight by the crown first

  5. Your AI knows your whole history.

    Settings · Connect your AI

  6. Intake against what you burnt.

    Settings · Have this phone hand over what Apple Health records

  7. Supplements that know when they run out.

    Record · See what needs reordering

  8. It never lies to you and never locks you out.

    Settings · Take your own data out of the product

The address, and how to add it

Add this address to your AI as a remote MCP server (Streamable HTTP). Your AI registers itself, opens a sign-in page here, and asks for your approval; after that it acts as you, under the same rules as this app.

How it signs in

Your client registers itself and asks you to approve what it may do — nothing to configure, no key to paste. Every call afterwards runs as you.

You can see every connected client, change what each may write, and disconnect any of them from Settings › Connection.

You need an account before a client can connect — the server has nothing to show an AI that is not signed in as somebody.

What this product runs, and what it does not

No chat window here, and no assistant of ours to pay for: yours is the one you already use. Nothing you say to it passes through here, only the calls it makes.
