Context Cost
This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

🟡shape_post(notes)
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.

"notes": {
"type": "string",

"maxLength": 4000,

}
},

"$schema": "http://json-schema.org/draft-07/schema#"
}🟡create_draft(body, platforms, proposedTime)
Save a post as a DRAFT in the user's posthell queue. It is never published by this tool - the user approves it in the dashboard. Optionally propose a publish time (pre-fills their scheduler) and limit which platforms it targets (default: every connected account).

}🟢list_posts(status, limit)
Read the user's recent posts and drafts with per-platform status. Published posts include engagement metrics (likes, comments, shares, engagementRate - impressions on plans with full analytics) once analytics have synced. Use it to avoid duplicating a topic AND to learn which topics performed before drafting the next post.
Input Schema
{
"type": "object",
"properties": {
"status": {
"description": "Filter by status (posted and published are synonyms)",
"type": "string",
"enum": [
"draft",
"scheduled",
"posted",

"partly_posted"

},
"limit": {
"description": "Max results (default 15)",
"type": "integer",
"minimum": 1,
"maximum": 50
}
},

}🟡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.
