For ChatGPT, Claude and other AI assistants
Ask Claude, ChatGPT or another assistant to colorize or restore an old photo. It works with your Recolor the Past account and credits, and only within the monthly limit you approve.
You
Here's a photo of my grandparents from 1952. Can you colorize it?
Assistant
Done. It used 1 credit from your Recolor the Past balance. Here's the colorized photo and a link to download it in full resolution.
Four steps, and you approve everything that matters.
Add Recolor the Past to your assistant, sign in and approve the connection. You choose how many credits it may spend each month.
Give the assistant an image link or attach the file. It can also send you an upload link so you can add photos yourself.
It picks the options, such as adding color or repairing faces and scratches, tells you the cost and orders the photo.
You get the colorized result and a download link. It's also saved under Photos on the website.
You always complete payments yourself. An assistant can only create a checkout link. It can never pay or see your card.
Recolor the Past works as an MCP server. Add it to your assistant with this address, then sign in and approve the connection.
https://api.recolorthepast.com/mcpMenu names change from time to time. Custom connectors may need a paid plan with your assistant's provider.

}These are the tools your assistant sees once it's connected. Billing tools only create links; you complete any payment yourself.
| Tool | What it does | Access |
|---|---|---|
get_account | Shows your credit balance, your plan, whether your free full-resolution photo is still available and this connection's monthly cap. | Account |
get_pricing | Lists the credit packs, the Pro plan and what each option costs. | Account |
estimate_cost | Works out how many credits a set of options will cost. | Account |
colorize_photo | Colorizes or restores a photo from an image link or an attached file. A full-resolution result spends credits. | Photos |
get_photo | Checks progress. When the photo is ready, it returns a download link and a preview. | Photos |
list_photos | Lists your recent photos, including the ones you uploaded on the website. | Photos |
upgrade_to_full_resolution | Orders the full-resolution version of a preview. Your first one is free. | Photos |
delete_photo | Permanently deletes a photo and its files. | Photos |
get_upload_link | Gives you a link where you can upload photos yourself. | Photos |
buy_credits | Creates a checkout link for a credit pack. You pay on the secure checkout page. | Billing links |
subscribe_pro | Creates a checkout link for the Pro plan, or a billing link if you already subscribe. | Billing links |
manage_billing | Creates a link to your billing page, where you can change or cancel your plan. | Billing links |
There's no separate AI price. Your assistant uses the same credits as the website: previews are free, and adding color to a photo in full resolution costs 1 credit. Optional repairs cost extra, and the assistant can check the cost before it orders.
See all prices350 credits every month. Unused credits roll over, up to 700.
One-off packs with no subscription. The same balance works on the website, in the app and with your assistants.
When you approve an assistant, you choose how many credits it may spend each calendar month. You can change the cap at any time.
You stay in control of every connection.
Every assistant and API key has its own monthly credit cap. Work that would go over it is refused until you raise the cap or the next month starts.
See and disconnect assistants and API keys in Account → AI assistants & API. Access stops immediately.
A connected assistant can work with your photos and create billing links. It can never change your password or two-step sign-in, see your billing details or delete your account.
Assistants can only create checkout links. Every payment happens on the secure checkout page, and only you can complete it.
Photos sent by an assistant follow the normal retention and deletion rules. They are never used to train AI.
Build your own integration with a personal API key and the REST API.
Create a key in Account → AI assistants & API. It's shown only once, so store it safely. Each key has its own monthly credit cap and can be revoked at any time.
Import the OpenAPI 3.1 description into your tools to see every endpoint an API key can use.
Send the key as a Bearer token. Ordering a full-resolution render spends credits.
