# Introduction

> Brief once. Reach every seller. Let agents do the legwork.

Semicola is an ad gateway built on AdCP. Buyers send one brief to many media sellers, through
the Semicola app, through Claude or ChatGPT over MCP, or through their own agent. Media companies
open a storefront whose agent answers briefs in their own voice, under their own rules.
