Cursor Flux Cloud Prompt/deploy_on_flux
How to: Cursor Flux Cloud deploy_on_flux
Add Flux Cloud to Cursor
-
01
Open ~/.cursor/mcp.json and merge this in. Keep any servers already there.
{
"mcpServers": {
"flux-cloud-mcp": {
"url": "https://mcp.runonflux.com/mcp"
}
}
}-
02
Save the file and restart Cursor.

deploy_on_flux is surfaced in the client's prompt or command menu. Unlike a tool, you invoke it deliberately — Cursor will not call it for you.

Same prompt, other clients
Read from the server itself, by connecting to it and calling prompts/list on 24 September 2026.
A listing does not declare its prompts, so asking is the only way to know them, and this
is what the server actually offers rather than what its listing claims. Names only are
stored; connect the server for each prompt's arguments.
