OpenClaw + PostAxis

Automate social media with OpenClaw

OpenClaw runs around the clock, so it can run your posting queue too. Connect PostAxis and your agent can keep a content calendar full and on schedule.

  • Connect with one prompt
  • OAuth, or an API key for headless servers
  • Keep a 30-day calendar filled automatically

Set up OpenClaw with PostAxis

Plug PostAxis into OpenClaw once, then talk to it like you would to whoever runs your accounts. Every click is in the full guide below.

Plug in about a minute

Step 1 of 2

Connect OpenClaw with one message

Send OpenClaw the prompt below. It adds the PostAxis MCP server and walks you through the sign-in.

  • PostAxis account
  • A connected social account
  • OpenClaw installed
Prompt
Connect to the PostAxis social media scheduler MCP server at https://postaxis.io/api/mcp

Running headless? Configure the server with the header Authorization: Bearer YOUR_API_KEY instead (needs the API add-on).

Talk

Step 2 of 2

Then tell OpenClaw what you need

OpenClaw picks the PostAxis tools it needs. Scheduled posts go out on time whether or not the chat is still open.

Try asking

  • Which accounts can you post to?
  • What goes out this week?
  • Keep that one as a draft

Every Monday, plan the week’s posts for X and LinkedIn from our blog and schedule them at 10:00.

Done for this week: 5 posts scheduled at 10:00, Monday to Friday, on X and LinkedIn. I’ll plan next week on Monday.

What can OpenClaw do with PostAxis?

Everything PostAxis does in the dashboard that makes sense to do by asking: writing, scheduling, editing, publishing and checking your queue.

Sentences in, posts out

Describe the post in your own words. OpenClaw turns it into posts and PostAxis handles the scheduling.

Every network you run

Instagram, TikTok, YouTube, X, LinkedIn, Facebook, Threads and Telegram, from a single message.

Checked before it’s saved

Caption length, media count, video length and format are checked for every network before anything is saved.

Weeks ahead in one go

Ask for a week or a month. OpenClaw can dry-run up to 50 posts at once, show you the plan, then schedule it.

Your images and video

Attach images and videos from a link, or get a one-time upload link for files on your computer.

Your accounts, your call

OpenClaw signs in as you and can only reach accounts connected in your workspace. Cut it off from Settings whenever you like.

What is OpenClaw?

OpenClaw is an always-on personal AI agent you message from chat apps like WhatsApp, Telegram or Slack. It runs on its own gateway and works on tasks in the background.

With PostAxis connected, it can keep your posting calendar full: plan the week, schedule posts and report back, all from a chat message.

What can you ask OpenClaw to post?

Brief it like a person: what it’s about, where it goes, when. Four requests that work well with OpenClaw:

  1. Long task

    Fill a 30-day calendar

    Plan 30 days of posts for X, LinkedIn and Threads, validate them all, show me the calendar and schedule after I approve.

    To OpenClaw
  2. Research

    Research, then post

    Find three news stories in our industry from this week and schedule a LinkedIn post with our take on each, Tuesday to Thursday at 9:00.

    To OpenClaw
  3. Report

    Review the week

    Tell me which posts published this week and which failed, and reschedule the failed ones for tomorrow.

    To OpenClaw
  4. Right now

    Post an update immediately

    The outage is fixed. Post a short all-clear to our Telegram channel and Facebook page now and confirm when both are up.

    To OpenClaw

How does OpenClaw talk to PostAxis?

Through MCP, the Model Context Protocol: an open standard for giving AI apps tools. PostAxis runs an MCP server; OpenClaw connects to it and gets 11 tools that work on your account, nothing more. Full MCP reference

From your message to a scheduled post

What happens between you hitting enter and the post showing up in your calendar.

  • You write one message: what, where, when
  • OpenClaw looks up your accounts and the limits of each network you named
  • It drafts a version per network and sends them to PostAxis
  • PostAxis checks every version and saves it as scheduled, a draft or live
  • The post sits in your calendar, editable until it goes out

Do posts go out if OpenClaw is offline?

Yes. Once a post is scheduled, PostAxis publishes it at the set time. OpenClaw only needs to be running when it creates or changes posts.

Can OpenClaw schedule 30 days of posts at once?

Yes. OpenClaw can send up to 50 posts in one bulk call. Ask it to validate first: PostAxis checks every post and saves nothing, so you can review the plan before it is scheduled.

Plan 30 days of posts for X and LinkedIn about our product, validate them, show me the calendar, then schedule.

Done. Here’s what I did:

  • Validated 30 posts, each going to X and LinkedIn, 0 problems
  • Showed the calendar and waited for approval
  • Scheduled all 30 for 10:00 each day

Example conversation

How does OpenClaw sign in to PostAxis?

OpenClaw signs in to PostAxis, never to your social networks. Your Instagram, X or LinkedIn accounts stay connected to PostAxis, and you can revoke OpenClaw’s access at any time.

Every plan✓ Used by OpenClaw

OAuth sign-in

  1. OpenClaw opens the PostAxis sign-in in your browser
  2. You log in and click Approve
  3. It gets access to your account only, until you revoke it

Best for apps you use yourself: ChatGPT, Claude, Cursor, Codex and most others

API add-on

API key

  1. Create a key under Settings → API keys
  2. Send it as Authorization: Bearer KEY, or in the URL for clients that only take a URL
  3. Revoke the key any time and access stops at once

Best for servers and automations with no browser: n8n, Grok, Manus, headless agents

If something doesn’t work

The most common problems when connecting OpenClaw, and how to fix them.

OpenClaw runs on a server with no browser

Use an API key instead (needs the API add-on): add the server with the header Authorization: Bearer YOUR_API_KEY.

The agent says no accounts are connected

Connect at least one social account under Accounts in PostAxis. If you use several workspaces, tell the agent which one, for example “use my Acme workspace”.

401 Unauthorized or “sign in again”

The sign-in expired or was revoked. Reconnect from your agent (it opens the PostAxis sign-in again). With an API key, check the key is still active under Settings → API keys.

A post was rejected before saving

PostAxis checks each network’s rules first: caption length, media count, video length and format. The error says what to change; ask the agent to fix it and try again.

Posts are scheduled at the wrong time

Say the timezone in your request, for example “9:00 Europe/Berlin”. Without one, the agent uses the timezone it was told or UTC.

I want to stop an agent from posting

Open Settings → API keys in PostAxis. Revoke the agent under Connected agents, or revoke its API key. It loses access immediately.

OpenClaw and PostAxis: questions

Is it safe to let an agent post on its own?

You stay in control: everything appears in your PostAxis calendar, drafts can be reviewed first, and you can revoke the agent at any time. Limits (300 posts a day, 50 per batch) protect your accounts.

What is the PostAxis MCP server?

It’s a remote Model Context Protocol server at https://postaxis.io/api/mcp that gives AI agents 11 tools to list your accounts, upload media and create, schedule, edit and delete posts in PostAxis.

Which social networks are supported?

Instagram (posts, Reels, carousels), TikTok (videos and photo posts), YouTube Shorts, X, LinkedIn, Facebook Pages, Threads and Telegram channels.

How much does it cost?

MCP access with OAuth is included in every PostAxis plan, and every plan starts with a 7-day free trial. API keys need the API add-on.

What stops an agent from posting something wrong?

PostAxis checks every post against each network’s rules before saving, the agent can preview bulk plans without saving them, everything shows up in your calendar, and you can revoke an agent at any time in Settings → API keys.
