Available tools 4

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

draft
create_draft
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).
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-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.
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.

Posthell — questions

Answers built from our own checks of this server.

What can Posthell do?
It exposes 4 tools, read directly from the server on our last check. Among them: create_draft, get_growth, 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 11 of 91 checks got a reply (12.1%), average response time 493 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 with the file path 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 4 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Posthell?
It answers our handshake in 493 ms on average, which is faster than 32% of all working MCP servers we measure. The comparison comes from our own checks across the whole registry, every 15 minutes.
