Zernio

Use this when the user wants to delete a draft, scheduled or failed post so it will not be published. This removes the post from Zernio and cannot be undone. Posts that are already published are left untouched and this tool reports that. Requires the post id from list_posts.

cancel_scheduled_post

Use this whenever the user asks whether a text or media can go out, fits, or is allowed on a chosen platform, for example character limits or required media, and before scheduling when in doubt. Use it instead of answering from general knowledge: the rules are enforced by Zernio. Nothing is created. Returns valid true/false plus each error or warning with the platform it applies to.

validate_post

Use this when the user wants to change the text, media, title or publish time of a post that has not been published yet (draft, scheduled or failed). Only the fields given are changed; new media_urls replace the existing media. Published posts cannot be edited here. Requires the post id from list_posts.

update_scheduled_post

Use this when the user asks how a specific published post performed: impressions, reach, likes, comments, shares, saves, clicks, views and engagement rate, per platform. Numbers sync from the platforms periodically, so a just-published post may report pending data. Requires the post id from list_posts.

get_post_analytics

Use this when the user asks when they should post for the most engagement. Computed from the engagement history of the user's own published posts, as weekday and hour in UTC, best first. Filter by account_id or platform. Returns nothing useful until the account has published posts with synced analytics.

get_best_time_to_post

Use this when the user asks how their accounts or platforms performed over a period, for example 'how did Instagram do last month'. Returns daily totals (impressions, reach, likes, comments, shares, saves, clicks, views) and per-platform totals for the date range, defaulting to the last 30 days. Filter by account_id or platform. For a single post use get_post_analytics.

get_account_analytics

Use this when the user asks about one specific post: its full text, media, schedule, per-platform status, public links or failure reason. Requires the post id from list_posts or from an earlier create result.

get_post

Use this to identify which Zernio account is connected, for example when the user has several Zernio accounts or asks who they are signed in as. Returns the stable account id plus name and email when available. Do not use it to look up other people.

get_profile

Use this when the user wants to see which social media accounts are connected to Zernio, or before scheduling or publishing so you can pass the right account_ids. Returns each account's id, platform, username and connection status. Optionally filter by platform (instagram, tiktok, youtube, twitter, linkedin, facebook, threads, pinterest, reddit, bluesky, googlebusiness, telegram, snapchat, discord, slack).

list_social_accounts

Use this when the user wants to review their scheduled, draft, published or failed posts, for example 'what is scheduled this week' or 'which posts failed'. Returns each post's id, status, text, scheduled time and per-platform status. Newest first. For one post's full details use get_post; for performance numbers use get_post_analytics.
