Available tools 6

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

accounts
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 name or account handles to create_draft or publish_post.
draft
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 are what would stop it publishing; fix them by calling again.
growth
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.
posts
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 synced. Use it to avoid duplicating a topic AND to learn which topics performed before drafting the next post.
shape
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.
upload
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 publish_post. Files are stored for good, so a draft keeps its video. Up to 50MB. Types: JPG, PNG, GIF, WebP, MP4, MOV, WebM, or PDF.

Posthell — questions

Answers built from our own checks of this server.

What can Posthell do?
It exposes 6 tools, read directly from the server on our last check. Among them: create_draft, get_growth, get_upload_url, list_accounts, list_posts, shape_post. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Posthell working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 91 checks got a reply (0.0%), average response time 157 ms. The bar chart above shows every period we have measured.
The registry lists Posthell as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Posthell?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Posthell need an API key?
No. Posthell completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 6 of them are readable on this page. This is what we observed, not what the docs claim.
