# Introduction

> Postbase is an open-source, MCP-native, multi-channel social scheduler.

Postbase lets you write once and publish everywhere — X, LinkedIn, Instagram,
TikTok, YouTube, Bluesky, and Mastodon — from a single composer, calendar, and
media library. It's **open source** (AGPL), **self-hostable**, and **MCP-native**,
so an AI agent can draft and schedule posts for you over the Model Context
Protocol.

    and publish for you — with or without an API key.

    A small REST API to list channels and create or cancel scheduled posts from

## How it's organised

<Note>
  The docs are split by what you're trying to do — use the product, wire up an
  agent, call the API, or run your own instance.
