Common questions

Is Postemi: Social Media Scheduler safe?

It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.

What keys or codes does it need?

The registry does not list a required key, though some servers ask you to sign in on first use.

Does it run on my computer or in the cloud?

It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Is it still maintained?

The GitHub repo last changed –, and the latest version (1.0.0) reached the registry 10 days ago.

Which apps can use it?

Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.

What can I use instead?

Postemi CLI

Social media scheduling from the command line, or from your AI agent.

Postemi (https://postemi.com) is a social media scheduler, and this is its command-line tool. It uses the same public API as the web app: what you schedule here shows up in your Postemi calendar, and what you schedule there you can see here too.

Channels: 37 platforms and apps, including Facebook, Instagram, X, LinkedIn, TikTok, YouTube, Threads, Bluesky, Pinterest and Mastodon.

Plan: the CLI, the API and MCP need the Pro plan or higher (Pro, Creator or Team). Basic has no API access.

SKILL.md is the full command reference, written for AI agents. Show it to Claude, ChatGPT, Codex, OpenClaw or Hermes and they can use the whole CLI with no further explanation.

Install

npm install -g postemi

postemi --help

Node.js 18 or newer.

Sign in

postemi auth:login     # device flow: opens postemi.com/app/device in the browser

postemi auth:status # checks the credential postemi auth:logout # deletes the stored credential

You approve the login in the browser while signed in to Postemi, and choose there which workspace and which channels the key may reach. The CLI stores it in ~/.postemi/credentials.json (mode 0600).

No account yet? Create one from the terminal:

postemi auth:signup --email anna@example.com    # e-mails a code, asks for it and for the terms

postemi auth:signup --email anna@example.com --code 123456 --accept-terms --workspace-name "Anna's Cafe"

The person must agree to https://postemi.com/terms and https://postemi.com/privacy first. An account made with postemi auth:signup has no free trial: next come postemi billing:plans and postemi billing:subscribe. Signing up at https://postemi.com/app/signup instead starts a 7-day free trial; then run postemi auth:login.

For a server, CI or an agent without a browser, use an API key from Settings, Developers in the web app:

export POSTEMI_API_KEY=your_api_key

Variable	Default	Purpose
`POSTEMI_API_KEY`	none	API key, when you do not use `auth:login`
`POSTEMI_API_URL`	`https://api.postemi.com`	API base
`POSTEMI_WORKSPACE`	none	Workspace id for every command (same as `--workspace`)
`POSTEMI_TIMEZONE`	none	IANA zone for dates written without an offset
`POSTEMI_AUTH_SERVER`	`https://api.postemi.com`	Where `auth:login` runs the device flow
`POSTEMI_CLIENT_NAME`	`Postemi CLI`	Name shown on the approval page

Stored credentials from auth:login take precedence over POSTEMI_API_KEY.

Quick start

postemi auth:status

postemi integrations:list # your channels and their ids postemi config:set timezone Europe/London # once: how to read dates without an offset

IMG=$(postemi upload ./photo.jpg | jq -r '.path') postemi posts:create -c "Hello from the terminal" -m "$IMG" \ -s "2026-12-31 09:00" -i " "

Results are JSON on stdout; status lines and errors go to stderr, and every failure exits 1. Run postemi --help for each command.

Agent skills (optional)

The CLI can install its skills into the coding agents on your machine (Claude Code ~/.claude/skills, Codex ~/.codex/skills or $CODEX_HOME/skills, Cursor ~/.cursor/skills, Grok Build ~/.grok/skills). The core postemi skill comes with any of them; the other two are optional:

postemi skills list                    # core, writing, growth: installed where

postemi skills add writing # ideas, hooks, formatting, templates postemi skills add growth # niche, cadence, 30-day plan postemi skills add all --agent claude --yes postemi skills remove growth

After postemi auth:login on a terminal the CLI asks once whether you want the writing and the growth skill (default No) and remembers the answers in ~/.postemi/config.json. It never asks when an agent or a script runs it (no terminal, --json, or CI set); it prints one hint line instead, once. With several agents found it asks which; --agent and --yes skip that.

SKILL.md: every command, flag and rule
PROVIDER_SETTINGS.md: per-channel settings

Plugins for AI agents

This repository also holds the Postemi plugins, in plugins/:

Folder	For	What it is
`plugins/postemi-mcp`	Claude (chat, desktop, Code)	The hosted MCP server `https://mcp.postemi.com/mcp` plus a skill
`plugins/postemi-cli`	Claude Code	This CLI's skill; the agent runs `postemi` commands
`plugins/postemi-chatgpt`	ChatGPT	The ChatGPT app package
`plugins/postemi-cursor`	Cursor	MCP server, skill and commands
`plugins/postemi-grok`	Grok Build	MCP server, skill and commands
`plugins/postemi-growth`	Claude Code, Cursor, Grok Build	Optional: the growth skill only

In Claude Code:

claude plugin marketplace add norbertlevente/postemi-agent

claude plugin install postemi@postemi-agent # MCP server claude plugin install postemi-cli@postemi-agent # CLI skill

The skill on its own (for OpenClaw and other agents) is skills/postemi/SKILL.md.

Writing and growth skills

Three more skills help the agent write the posts, not only schedule them:

Skill	What it teaches	In the plugins
`skills/postemi-writing`	post ideas, hooks and headlines, opening lines, formatting, threads, each network's writing rules, a check before publishing	in every main plugin
`skills/postemi-templates`	the template and hook library of the Postemi composer, generated from the web app	in every main plugin, with writing
`skills/postemi-growth`	choosing networks and a first niche, a 30-day test, reading the numbers, cadence, 30 angles for one topic, repurposing, bios and profile links, a weekly review	optional: its own plugin, `plugins/postemi-growth`

claude plugin install postemi-growth@postemi-agent   # the optional growth plugin

With the CLI, writing and growth are both optional; see below.

Development

pnpm install

pnpm build # dist/index.js pnpm test # type check, build, unit tests (test/), scripts/check.mjs (manifests, skill copies, no other-brand text) node dist/index.js --help

pnpm sync:templates ../postemi/src/lib/app/templates # regenerate skills/postemi-templates/reference from the web app pnpm sync:skills # copy writing and templates into the main plugins, growth into postemi-growth
