How to automate social media posts

Short answer. Automation here means one of four things: a queue that publishes on a schedule, a spreadsheet or feed that drives it, a workflow tool like n8n or Make, or an AI agent calling a publishing API directly. The first is enough for most people; the last one is only worth it if you already run agents.

Workflow toolChaining generation, approval and publishingAn n8n or Make account; templates exist for this
AI agent (MCP)Agents that decide what to post themselvesAn MCP server the agent can call

The part automation does not solve

Whatever you build, the platform approvals are still yours unless the tool already holds them. Publishing to TikTok on behalf of a user requires passing TikTok's Content Posting audit. Instagram requires a Meta app review, an Instagram Business account and a linked Facebook Page. Reddit's self-serve app creation for this use case is effectively closed — it is a Data Access Request and a wait. Budget for that before choosing to self-host.

Automating without becoming a spammer

Two failure modes are worth naming. The first is repetition: a rotating queue of the same fifteen posts is visible to anyone who follows you, and it is worse than posting nothing. The second is identical copy across networks, which every algorithm discounts. If you automate, automate variety — different angle, different length, different network conventions — or automate less often.

Start free — 1 brand, 10 posts a month, no card

10 posts a month and 2 networks per post on the free plan. Starter is $9/month for three brands, 1,000 posts and every network in each post; Pro $29 for ten brands and unlimited posts (fair use). Priced per brand — every network connects free, no per-network fee.

Questions people ask

How can I automate social media posts for free?
Use a free tier with a queue: PostWire (1 brand, 10 posts a month, 2 networks per post, 3 scheduled posts at a time, no card) or Buffer (3 channels, 10 scheduled posts per channel). For workflow automation, n8n can be self-hosted for free and driven against a publishing API.
Can AI post to social media automatically?
Yes. An AI agent can publish through an MCP server or a REST API — PostWire exposes both, so Claude, Cursor or a custom agent publishes with one tool call. The platform side is unchanged: TikTok and YouTube still need a video, Instagram still refuses text-only posts.
Is automated posting against the platforms' rules?
Not when you publish through the official APIs, which is what these tools do. What breaks rules is scraping, browser automation pretending to be a person, or mass-posting identical content. Publishing your own content through an approved app is exactly what the APIs exist for.
