What it can do

  • Generate Posts: Smart Distribute — PostWire's native AI writer. Give ONE prompt (and optional media) and it writes the BEST NATIVE post for EACH platform: correct character limits, hashtag rules, SEO
  • Post To Social: Publish to one or more social platforms via PostWire, in parallel. For best results, first call generate_posts to get a NATIVE draft per platform, then pass them here as `per_platform`
  • Get Post Status: Check the processing/publish status of a post previously created with post_to_social.

What data it sees

Do you need an account

An API key from the service settings is required

Publish and schedule posts to TikTok, Instagram, YouTube, LinkedIn, X, Bluesky, Mastodon, Telegram and Discord from a single tool call. Smart Distribute writes the native version for each network — the right length, hashtags, SEO and format — then publishes it now or queues it for later. Connect an account once with OAuth; PostWire handles tokens, refreshes and per-platform rules (which networks require video, which reject text-only). Free tier, no card: 1 brand, 30 posts a month. Flat per-brand pricing after that — no per-profile charge.

generate_postsSmart Distribute — PostWire's native AI writer. Give ONE prompt (and optional media) and it writes the BEST NATIVE post for EACH platform: correct character limits, hashtag rules, SEO title+tags for YouTube, hook-first captions for TikTok/Reels, professional framing for LinkedIn (link-in-comment), thread-friendly text for X (link-in-reply), CamelCase tags for Mastodon, and more. It does NOT send the same text everywhere — each platform gets its own optimized draft. Returns { drafts: { <platform>: { text, title?, tags? } } }. Review/edit the drafts, then pass them to post_to_social as per_platform.
post_to_socialPublish to one or more social platforms via PostWire, in parallel. For best results, first call generate_posts to get a NATIVE draft per platform, then pass them here as `per_platform` (PostWire never just copies the same text everywhere). Or pass a single `text` for a quick same-everywhere post. Connect accounts first at https://postwire.io/dashboard.html. Returns per-platform results (each has an id you can pass to get_post_status).
get_post_statusCheck the processing/publish status of a post previously created with post_to_social.
list_platformsList the social platforms PostWire supports and the fields each needs.
