PostWire's Smart Distribute writes the best native post for each network from a single prompt — the right hashtags, length, SEO and format per platform, never the same text everywhere. One MCP server + REST API for TikTok, Instagram, YouTube, LinkedIn, X, Bluesky & more. Flat per-brand pricing.
Get your API key — free See how it worksOne prompt + media → an optimized post for each network. YouTube gets an SEO title + tags, TikTok a hook-first caption, LinkedIn pro framing with the link in the comment, X thread-ready text. Not copy-paste — which every algorithm punishes.
A real MCP server (generate_posts + post_to_social), not a REST API with MCP bolted on. Plug into Claude, Cursor or any agent — it writes and posts out of the box.
50 brands for $99 — Ayrshare charges roughly $779 for the same. AI generation included free; you pay for brands, not per post.
You connect each social account you own through a secure OAuth flow. PostWire only ever posts the content you (or your agent) explicitly send, and only to accounts you have authorized.

PostWire vs Ayrshare · PostWire vs Upload-Post
PostWire is a social-media publishing platform operated as a hosted SaaS. Developers, agencies and AI agents use our REST API and MCP server to publish content to the social accounts they own and have explicitly connected. We act as a tool on your behalf: we never post without your request, never sell user data, and you can disconnect any account or delete your data at any time.
No. With PostWire's Smart Distribute you write one prompt and it generates a different native post for each network — the right length, hashtags, format and SEO per platform — instead of copy-pasting the same text everywhere.
Yes. From a single request PostWire produces a distinct caption per platform — a short hook for X, a long-form post for LinkedIn, a hook-first caption for TikTok — and publishes them all in one call.
Posting identical text everywhere can suppress engagement, because each algorithm favors native content. PostWire avoids this by giving every platform its own natively-formatted post, which is what turns cross-posting into a reach gain rather than a penalty.
Give PostWire one prompt (and optional media) and it transforms it into each platform's native format in a single step — no manual reformatting. You can edit any draft before publishing.
Use a tool that varies the post per network. PostWire's Smart Distribute writes native copy for each platform so your posts read as made-for-the-feed, not an obvious copy-paste.
Yes. PostWire has a free tier (1 brand, 30 posts/month, no credit card) so you can connect your accounts and publish — including the AI generation — before paying anything.
Developers and agencies who manage many brands, and AI-agent builders who need their agents to publish to social media without writing per-platform integration code.
Through each platform's official OAuth flow. You authorize PostWire to post on your behalf; we store the access tokens encrypted and use them only to fulfill the posts you request.
Only what's required to identify the connected account (basic profile) and publish the content you send. See our Privacy Policy and Data deletion page.
Flat per-brand pricing: Free $0 (1 brand, 30 posts/mo, no card), Starter $9, Pro $29, Agency $99 for 50 brands, Scale $299 — no per-profile tax. 50 brands cost $99 vs roughly $779 on Ayrshare.
