Cue + PostAxis

Run your social media with a Cue agent

Cue is Manus’ app for personal agents, each with its own email, phone and computer. Give your social media agent the PostAxis connector and a clear responsibility, and it handles the posting.

Step 1 of 2

Give a Cue agent the PostAxis connector

Cue connectors take an API key. Create a PostAxis key, add PostAxis as a connector, and assign it to the agent that runs your social media.

PostAxis account
A connected social account

API add-on

Connector + responsibility

URL:     https://postaxis.io/api/mcp
API key: Bearer YOUR_API_KEY

Responsibility: You run my social media through PostAxis. First list my connected PostAxis accounts, then plan and schedule posts I approve.

Cue is in early access and its connector screens may change. The API key field expects “Bearer”, a space, then your key.

Step 2 of 2

Then tell Cue what you need

Cue 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

Plan next week: one post a day on Instagram and Threads at 18:00.

Your week is planned: 5 posts, Monday to Friday at 18:00. I will plan the next week on Sunday.

Full setup guide for Cue

Every step from a new PostAxis account to your first scheduled post. Takes about 3 minutes once your accounts are connected.

1
Create your PostAxis account
Sign up at app.postaxis.io. Every plan starts with a 7-day free trial and includes MCP access with OAuth sign-in. Create an account
2
Connect your social accounts
Open Accounts in PostAxis and connect the networks you want to post to: Instagram, TikTok, YouTube, X, LinkedIn, Facebook, Threads or Telegram. Your agent can only post to accounts connected here, and it never sees your social media passwords. Open Accounts
3
Create an API key
In PostAxis open Settings → API keys and click Create API key. This needs the API add-on.
4
Add the connector
Open Cue’s connectors and add a custom MCP connector with this URL. In the API key field enter “Bearer”, a space, then your key.
Copy this
```
URL:     https://postaxis.io/api/mcp
API key: Bearer YOUR_API_KEY
```

Assign it to an agent

Give the connector to your social media agent with a clear responsibility.

Copy this

You run my social media through PostAxis. First list my connected PostAxis accounts, then plan and schedule posts I approve.

6
Check and set a routine
Ask the agent to list your accounts, then set a routine for recurring posts.

What can Cue 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. Cue 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. Cue 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.

A key you can revoke

Cue uses an API key you create and can revoke at any time. It only reaches accounts connected in your PostAxis workspace.

What is Cue?

Cue is Manus’ app for personal agents. Each agent gets its own email, phone number, wallet and computer, and owns a responsibility you define.

Give one agent PostAxis and the job of running your social media, and it plans, schedules and reports on your posts.

What can you ask Cue to post?

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

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

How does Cue talk to PostAxis?

Through MCP, the Model Context Protocol: an open standard for giving AI apps tools. PostAxis runs an MCP server; Cue 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
Cue 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

Can A Cue agent schedule 30 days of posts at once?

Yes. A Cue agent 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 Cue sign in to PostAxis?

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

API add-on✓ Used by Cue

API key

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

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

Every plan

OAuth sign-in

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

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

If something doesn’t work

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

There is no custom connector option

Cue is in early access and its connector screens can change. If custom MCP connectors are not available on your account yet, ask your agent to connect to the MCP URL with the Bearer header.

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.

Cue and PostAxis: questions

How is Cue different from Manus?

Both come from Manus. Manus runs tasks you give it; Cue gives you named personal agents with their own email, phone and computer that own an ongoing responsibility, like running your social media.

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.
