Tools 8 found in our last check

• shape_post

  Turn rough notes about what the user did (shipped a feature, fixed a bug, hit a number) into 2-3 finished social-post angles in the user's voice. Grounded only in the notes - never invents facts. Uses one AI generation from the user's monthly quota.

• list_accounts

  The user's connected social accounts (id, network, handle), their account groups (a named set, e.g. one business's Instagram + YouTube), and what each network needs: caption limit, whether it needs a photo or video, and the settings it takes. Call this first, then pass a group n…

• get_upload_url

  Use this to post a file from the user's computer (a video you rendered, a photo). Returns uploadUrl and mediaUrl: PUT the raw file bytes to uploadUrl with its Content-Type header (the curl line in the result does it), then pass mediaUrl in the media list of create_draft or publi…

• create_draft

  Save a post as a DRAFT in the user's posthell queue, with any photos or videos and per-network settings (Instagram Reel cover, YouTube title/tags). Nothing is published by this tool: the user approves it in the dashboard. Optionally propose a publish time. Warnings in the result…

• list_posts

  Read the user's recent posts and drafts with per-network status, the live link once a post is up, and the reason when one failed. Published posts include engagement metrics (likes, comments, shares, engagementRate - impressions on plans with full analytics) once analytics have s…

• reschedule_post

  Change when a post goes out. Works on a post in the calendar (scheduled) and on a draft (its suggested time). Get the id from list_posts. A scheduled post is taken out of the network's queue and queued again at the new time; every network it was going to moves together.

• edit_post

  Change the caption (body), a network's own caption (overrides), and/or the suggested time of a DRAFT. Scheduled posts can only be moved with reschedule_post: changing the text of a post that is already scheduled needs a key the user has allowed to publish. Get the id from list_p…

• get_growth

  The user's follower counts and 7-day growth per connected network, plus which network is growing fastest. Use this to decide where a post matters most or to report progress.
