# Variafy

> Variafy is a remote MCP server that lets AI assistants such as Claude, ChatGPT and Cursor work with Meta ad accounts on behalf of their owner. Reads are free and change nothing. Every change takes two calls: a preview, then a confirmation token. Anything that can increase ad spend is never applied from chat: a signed-in person approves it in the console.

MCP endpoint: https://www.variafy.com/mcp (Streamable HTTP; OAuth 2.1, or the header Authorization: Bearer sk_live_… for clients without OAuth). Start with the start_here tool.

HTTP API: the same operations without an assistant — GET https://www.variafy.com/v1/tools lists them, POST https://www.variafy.com/v1/tools/<name> runs one, with the same key and the same two-step confirmation.
