The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
generate_posts ~215
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.
| Name | Type | Req | Description |
|---|---|---|---|
| media_url | string | – | optional public URL of the photo/video the post is about |
| platforms | array | yes | platforms to write for, e.g. ['youtube','tiktok','linkedin','x','bluesky','mastodon'] |
| prompt | string | yes | What you want to say / the idea to communicate. More detail = better output. |
No output schema declared.
No examples provided.
get_post_status ~57
Check the processing/publish status of a post previously created with post_to_social.
| Name | Type | Req | Description |
|---|---|---|---|
| id | string | yes | the post id returned by post_to_social |
| platform | string | yes | e.g. 'tiktok' or 'youtube' |
No output schema declared.
No examples provided.
list_platforms ~22
List the social platforms PostWire supports and the fields each needs.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
my_account ~23
Show the PostWire account: plan, monthly usage, and connected platforms.
Input schema present but exposes no named parameters.
No output schema declared.
No examples provided.
post_to_social ~251
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).
| Name | Type | Req | Description |
|---|---|---|---|
| per_platform | object | – | native drafts from generate_posts, e.g. { youtube:{text,title,tags}, x:{text} } |
| photo_url | string | – | optional public URL of a photo |
| platforms | array | yes | e.g. ['tiktok','youtube','bluesky'] — posts to all in one call |
| privacy | string | – | optional: private | public | unlisted (YouTube) |
| text | string | – | post text / caption (shared fallback if a platform has no per_platform draft) |
| title | string | – | optional title (used by YouTube) |
| video_url | string | – | optional public URL of a video (required for TikTok/YouTube) |
No output schema declared.
No examples provided.
