PostKing · Social

Generate, approve, and schedule social posts on PostKing across LinkedIn, X, Instagram, Threads, and Facebook — plus content weeks and repurposing.

Handles the social-post lifecycle on PostKing: generating AI drafts, approving/scheduling them, running the recurring Smart Week cadence, repurposing existing content into new posts, and attaching visuals. Requires an active brand — use the postking skill's brand-pick flow first if one isn't set.

When to Use

Use this skill when the user wants to draft, approve, schedule, or reschedule a social post; set up or run a weekly/recurring posting cadence; turn a URL, blog article, or piece of text into platform posts; attach or change a post's image/card/quote/carousel; or browse trending posts for hook inspiration.

When NOT to Use

• Blog articles (writing, publishing, WordPress/Medium/Substack) → postking-blog.
• Landing pages or side pages → postking-landing-pages.
• Multi-channel campaign briefs and strategy (Storylines) → postking-storylines.
• Subreddit-specific matching or native Reddit rewrites → postking-reddit.
• Managing saved voice profiles themselves, or a standalone de-slop/AI-detection pass → postking-brand-voice.
• No active brand yet, or first-time social account connection → postking-getting-started.

• trends_list — trending-post hooks.

Procedure

Generate, approve, and schedule a post

1. generate_post({ platform, variations?, theme, voice?, brandId? }) — ALWAYS pass theme with the specific topic/angle/tone the user wants; omitting it produces a random brand theme. This call polls until generation completes and already saves the result to a single postId (variation 1 is the primary, saved content — all variations live under that one postId, never call it again to "get the others").
2. Show the variation(s) to the user; ask which one (if more than one) and what time.
3. approve_post({ postId, scheduledAt, timezone? }) — scheduledAt is a future ISO 8601 datetime. This is the free-tier choke point. There is no variation param on this MCP tool — via MCP you always approve the post's current saved content (variation 1). Picking a different generated variation to schedule is a CLI-only affordance (pking posts approve <id> --variation N).
4. get_calendar({ days }) — confirm it appears in the upcoming schedule.

Plan a content week (Smart Week)

1. get_weekly_schedule({ brandId? }) — view the current cadence, if any.
2. set_weekly_schedule({ enabled?, leadTimeDays?, timezone?, voiceProfileId?, dayConfigs, brandId? }) where dayConfigs is an array of { dayOfWeek (0=Sun…6=Sat), mediums: [{ medium, postsPerDay }] }. There are no monday/tuesday/… params and the flag is enabled, not enable — those are CLI-only sugar.
3. run_weekly_schedule_day({ date, brandId? }) — date is YYYY-MM-DD. This is the Smart Week engine; call it per day, or leave the schedule enabled to run automatically.
4. list_posts({ status: "created" }) → get_post({ postId }) to review each draft.
5. approve_post({ postId, scheduledAt, timezone? }) per draft.
6. get_calendar({ days: 7 }) — verify the final week.

Repurpose a URL, blog, or text into multi-platform posts

1. check_social_accounts({ brandId? }) — confirm which platforms are connected.
2. repurpose_content({ brandId, sourceType: "url", sourceUrl, targetType: "social", targetPlatforms: ["linkedin", "x"] }) — PostKing crawls the URL internally; do not fetch it yourself.
   • Text input: sourceType: "text", sourceContent: "<text>".
   • From an existing blog: sourceType: "blog", sourceBlogId: <articleId>.
   • From an existing post: sourceType: "social_post", sourcePostId: <postId>.
   • Optional: angle, variations, voiceProfileIds (single ID applies to all platforms, or ["x:id1","linkedin:id2"] per platform).
3. get_post({ postId }) per generated post — inspect before scheduling.
4. approve_post({ postId, scheduledAt }) — free-tier choke point.
5. get_calendar({}) — confirm.

Pick a visual for a post

1. generate_post_visual_options({ postId, platform }) — always run this first. Relay the numbered options to the user, especially the recommended one — the returned params ARE the spec, no need to render anything yourself.
2. pick_post_visual({ postId, platform, style?, variant?, assetId?, slot?, kind? }) — pass the chosen option's fields verbatim from step 1's response. There is no numeric pick param on the MCP tool (that's CLI-only sugar); you must supply one of style, assetId, or slot, or the tool errors. Pass kind: "quote" (or "card"/"photo"/etc.) when the chosen option is a quote/card template style — omitting kind defaults to "card" and rejects quote styles.
3. "Show me more" → regenerate_post_visual({ postId, platform, loadExternal: true }) pulls additional stock results, then re-run generate_post_visual_options.
4. clear_post_visual({ postId, platform }) to remove a pick. For carousels: set cards first (set_post_cards/edit_post_card), then generate_post_carousel({ postId }).

Trends as hooks

trends_list({ niche?, platform?, days?, limit?, sort? }) — niches: ai-saas, marketing, web3 (default ai-saas); platform currently only x. The crawler runs every 3 days; default window is 3 days. Feed results into generate_post's theme or repurpose_content's angle for hook inspiration.

CLI fast path

Pitfalls

• approve_post has no variation param via MCP. If the user wants a specific generated variation scheduled (not variation 1), that's a CLI-only affordance (--variation N); via MCP the only way is to work from the CLI, or use the visual editor link (editInVisualEditor, returned by generate_post/get_post) to edit the saved content directly.
• set_weekly_schedule needs dayConfigs, not per-day flags. Passing monday/tuesday/etc. or enable (instead of enabled) will fail validation.
• pick_post_visual needs an explicit style/assetId/slot. There is no index-based pick param — always call generate_post_visual_options first and copy its fields.
• Omitting theme on generate_post gives a random topic. Always pass it when the user wants specific content.
• Visuals are never auto-attached. generate_post prepares visual options but does not attach one — nothing changes until pick_post_visual is called.
• INSUFFICIENT_CREDITS / FREE_CAP_REACHED — surface the error envelope's checkoutUrl in one line and stop; don't retry or recap.

Verification

• get_credits({ detail: "short" }) — confirms auth and balance.
• check_social_accounts({}) — confirms at least one connected platform.
• list_posts({ status: "created", limit: 1 }) — confirms the brand/posts API is reachable.
