Most social media schedulers are built around a browser dashboard. If you'd rather schedule from a terminal, run posts from a script, or let a coding agent handle publishing, you need a scheduler you can drive from the command line. Here's what's available, starting with OneUp.

## Why work from the terminal

- **Automation:** call the scheduler from cron jobs, CI/CD pipelines, or shell scripts
- **AI agents:** a coding agent that already lives in your terminal can schedule, check, and fix posts without a separate integration
- **Speed:** for power users, one line in a terminal beats clicking through a form
- **Fewer context switches:** schedule a post without leaving the project you're working in

## OneUp

OneUp works from your terminal through coding agents. You connect OneUp's MCP server to Claude Code, Codex, or Cursor with a single command, then manage your social accounts and posts by describing what you want in plain language.

**Claude Code**

```bash bash
claude mcp add --transport http --scope user oneup "https://feed.oneupapp.io/mcp/oneup"

```

Then open Claude Code, run `/mcp`, select **oneup**, and authenticate.

**Codex**

```bash bash
codex mcp add oneup --url "https://feed.oneupapp.io/mcp/oneup"

```

If the browser authentication doesn't start on its own, run `codex mcp login oneup`, and check the setup with `codex mcp list`.

**Cursor**

Add OneUp to `~/.cursor/mcp.json` (or `.cursor/mcp.json` for a single project):

```json json
{
  "mcpServers": {
    "oneup": {
      "url": "https://feed.oneupapp.io/mcp/oneup"
    }
  }
}

```

Any other MCP client that supports remote HTTP servers and OAuth can connect to the same URL.

**How authentication works.** You generate an API key on OneUp's API Access page. During setup, OneUp opens a browser page where you enter the key and approve the agent's access. OneUp stores the key encrypted, and the agent receives an OAuth token instead of your key. You can review and revoke connections from the MCP Connections page.

**Check that it works.** Start a session and ask: _"Use OneUp to list my connected social accounts."_ If the agent returns your accounts, authentication and tool access are both working.

**What you can do from there.** OneUp's documentation covers:

- Listing categories, social accounts, Pinterest boards, and YouTube playlists
- Creating text, image, and video posts, and uploading media
- Listing, editing, deleting, and rescheduling scheduled, published, draft, and failed posts
- Fetching and replying to comments
- Reading and sending inbox messages
- Pulling analytics across the supported platforms

If you prefer to write your own scripts, the same functionality is available through OneUp's REST API.

**Best for:** teams that want one terminal workflow covering a very wide set of networks, and that are comfortable describing what they want rather than typing fixed subcommands.

## Other schedulers with a command-line tool

OneUp's terminal workflow is agent-driven. If you'd rather type fixed commands and flags, a few other tools ship a traditional CLI.

**Postiz.** The open-source Postiz project ships a CLI that wraps its public API. It supports scheduling posts, listing connected accounts, uploading media, and deleting posts across a large set of platforms, with JSON output on every command. It can also point at a self-hosted instance.

**ContentStudio.** ContentStudio's CLI is aimed at developers and AI agents. It covers scheduling posts, uploading media, managing approvals, and working with comments and connected accounts across networks including Facebook, LinkedIn, X, Instagram, YouTube, TikTok, Pinterest, and Google Business Profile.

**PostHero, Simplified, Postatron, and JuzPost.** Several smaller or newer tools publish their own CLIs on GitHub, each covering creating and scheduling posts from the terminal, with some adding analytics, media upload, or an accompanying MCP server. Coverage and maturity vary a lot, so check each project's documentation before depending on one.

## What about the big names?

At least one comparison reports that Buffer, Hootsuite, Later, and Publer are browser-first with no command-line client. That roundup comes from a competing CLI vendor, so verify it in each tool's own docs.

## Choosing between them

- **Widest network coverage, driven from Claude Code, Codex, or Cursor:** OneUp
- **Fixed subcommands, open source, and self-hostable:** Postiz
- **A traditional CLI with approvals and comment management:** ContentStudio
