Tools & Capabilities Breakdown

Postwire MCP Tools (5)

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 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, then pass to post_to_social as per_platform.

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` (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_status

Check the processing/publish status of a post previously created with post_to_social.
