What can Dify 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. Dify 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. Dify 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

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

What is Dify?

Dify is an open-source platform for building AI agents and workflows, in the cloud or self-hosted. It can add MCP servers as tool providers for every app in a workspace.

With PostAxis added, a Dify agent or workflow can write and schedule posts as part of a larger process.

What can you ask Dify to post?

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

Trigger
New article, new posts
When a new article appears in the RSS feed, write posts for X and LinkedIn and schedule them for 9:00 the next morning.
To Dify
Schedule
A weekly roundup
Every Friday at 16:00, publish a roundup of this week’s articles to our Telegram channel.
To Dify
Review first
Drafts for approval
When a form is submitted, write a LinkedIn and Facebook announcement and save it as a draft for review.
To Dify
Report
Review the week
Tell me which posts published this week and which failed, and reschedule the failed ones for tomorrow.
To Dify

How does Dify talk to PostAxis?

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

Agent app or workflow?

Use an Agent app when the AI decides what to post. Use a workflow with an Agent node when posting is one fixed step, for example after a new product is created.

How does Dify sign in to PostAxis?

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

Every plan✓ Used by Dify

OAuth sign-in

Dify 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

API add-on

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

If something doesn’t work

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

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.

Dify and PostAxis: questions

Self-hosted or cloud?

Both. Dify Cloud and self-hosted Dify can reach the PostAxis MCP server as long as the server has internet access.

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.
