Frequently asked questions
What is Refcat?
Search 1M real UI flows and 3.3M screens from shipped apps, sites, emails and games.
How do I install Refcat?

For other clients, paste the JSON configuration from this page into their MCP settings.
Does Refcat need an API key?
Yes. It expects Authorization, which you set in its configuration.
Who maintains Refcat?
It is published by app.refcat. AI.tn lists it but does not maintain or endorse it.
From the official MCP Registry. Listing is not an endorsement: review a server's code and permissions before giving it access to your data.
