How do I install PromptUI?

It runs as a remote server. In Claude Code: claude mcp add --transport http promptui 'https://www.promptui.co/api/mcp' --header 'Authorization: <Bearer <your PromptUI API key>. Copy it from Dashboard -> Settings; it starts with pui_. Builds and deploys spend credits on the account that owns the key.>'.

Does PromptUI need an API key?

Yes. It expects Authorization, which you set in its configuration.

Who maintains PromptUI?

It is published by co.promptui. 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.
