Postiz is the agentic social media scheduling platform that Meta Muse AI drives through the Postiz MCP server. Please keep a human in the loop. Last updated: September 2026. Part of the Postiz AI agents guide.

How to Connect Postiz to Meta Muse AI

Muse has no connector settings screen, so the chat is the setup. One message connects Postiz. It takes under a minute and nothing is installed on your device.

One connection powers every channel you run

Connect your accounts in Postiz once. From then on Muse can post to any of them, and Postiz publishes at the time you set.

What Can Meta Muse AI Do with Postiz?

With Postiz connected, Muse can draft, schedule and publish posts, generate images and videos for them, and plan a content calendar across every channel you have connected. Everything below happens from a normal chat message.

Just Ask in Plain English

Tell Muse what to post and when. It writes it, schedules it, and publishes it through Postiz. No menus, no forms.

30+ Platforms

Post to X, LinkedIn, Reddit, Instagram, YouTube, TikTok, and more, all from a single conversation with Muse.

Connect Once with a Message

No installs or technical setup. Paste one message with your MCP link into Muse and you're ready to go.

Plan & Schedule Ahead

Ask Muse to plan a week of content and pick the times. It schedules everything in Postiz so it goes out automatically.

Generate Images & Videos

Muse can generate images and videos through Postiz and attach them to your posts, all in the same request.

Stays in Your Account

The connector signs in with your own Postiz account, so Muse only touches the accounts you've already connected.

What is Meta Muse AI?

Meta Muse AI is a personal AI agent from Meta, launched in September 2026, that takes actions for you instead of only answering questions. It runs on a dedicated Muse Secure VM, lives in the Muse app for iOS and Android, on the web at muse.ai and inside WhatsApp, and reaches outside apps through connectors. A separate Sentinel agent checks outbound actions before they run.

Muse is rolling out in the US first. Postiz is not an official Muse connector yet. Until it lands in the Muse directory, you connect it yourself with the Postiz MCP link: same tools, same results.

Wherever You Chat

Ask Muse to post from the web, your phone, or WhatsApp. Postiz handles the publishing in the background.

Custom Connectors

Muse reaches outside tools through connectors it can build itself. The Postiz MCP server plugs in as one, exposing your channels as tools.

Saved Skills

The setup prompt asks Muse to save a skill, so every social media request goes through Postiz first. No reminding it.

What is the Postiz MCP?

The Postiz MCP is a hosted Model Context Protocol server that exposes your Postiz social media accounts to AI assistants as tools. MCP is the standard way assistants plug into apps, so Muse can post, schedule and report through Postiz without you opening a dashboard. Full details are on the Postiz MCP page.

How Muse Uses Postiz

Once the MCP link is saved as a connector, Muse discovers the Postiz tools automatically and calls them on your behalf when you ask it to post. Postiz isn't in the official Muse connector directory yet, so you add it yourself with the Postiz MCP link.

Send Muse your Postiz MCP link in one message
Muse discovers your connected accounts and platform rules
It composes posts with the right format for each platform
It schedules, drafts, or publishes, exactly as you asked
Works alongside Muse's other connectors like Gmail and Calendar

Schedule a post to X and LinkedIn for tomorrow at 9am announcing our new feature. Keep it short and upbeat.

Content calendar

Plan a whole week

Plan a week of posts about our launch and space them out across my channels at the best times.

Post with a generated image

Generate an image of our new dashboard and post it to Instagram and Threads with a short caption.

Community

Share with your community

Draft a Reddit post for r/SaaS about the new release and drop the link in our Discord announcements channel.

Can Muse Post on a Schedule Automatically?

Yes. Muse hands the schedule to Postiz, and Postiz publishes each post at the set time whether or not the Muse chat is open. Ask Muse to plan a week or a month of posts in one message, and the calendar lives in your Postiz account where you can review or edit it.

Batch a Calendar

One request like 'plan next week' turns into scheduled posts across your channels, spaced out at the times you choose.

Draft First, Publish Later

Ask Muse to save drafts instead of publishing. Review them in Postiz, then tell Muse to schedule the ones you approve.

Repurpose Across Channels

Give Muse one announcement and ask for a version per platform. It applies each platform's format and settings through Postiz.

Is It Safe to Let Muse Post for You?

The Postiz connector uses OAuth, so you approve access with a sign-in link and never paste an API key into the chat. Muse can only reach the channels you connected in Postiz, and Meta's Sentinel agent checks Muse's outbound actions before they run. Keep a human in the loop for anything public.

OAuth sign-in through your Postiz account, no API key in the chat
Muse only sees the social accounts you already connected in Postiz
Ask for drafts instead of publishing when you want to review first
Muse runs on a dedicated Secure VM and its Sentinel agent gates outbound actions

How Does Muse Compare to Other AI Assistants with Postiz?

Muse is the only assistant here that you connect purely by chatting, with no settings screen. The same Postiz MCP link works with ChatGPT, Claude and the coding agents, and every option gets the same Postiz tools once connected.

Assistant	How you connect Postiz	Where it runs	Image and video tools
Meta Muse AI	One chat message with the Postiz MCP link. Muse builds the connector itself and saves a skill.	Muse app (iOS, Android), muse.ai, WhatsApp	Yes, full toolset via the MCP link
ChatGPT	Official Postiz connector, or Settings > Connectors > custom connector with the MCP link.	chatgpt.com and the ChatGPT apps	Yes
Claude (claude.ai)	Official connector in the Claude directory, or a custom connector with the MCP link.	Claude web, desktop, mobile	Directory connector: no. Custom MCP link: yes
Claude Code, Cursor, Codex	Terminal install: claude mcp add, a marketplace plugin, or npx skills add gitroomhq/postiz-agent.	Your terminal or IDE	Yes

Which Social Media Platforms Can Muse Post To?

Muse can post to any of the 30+ platforms Postiz supports. Connect your accounts in Postiz once, then post to any of them just by asking Muse. Each platform below opens its Postiz channel page.

How Much Does It Cost to Use Muse with Postiz?

The Muse connector costs nothing extra. Postiz hosted plans start with a 7-day free trial. Meta describes Muse as free for most of what people need, with subscription plans for people who want to do more. Compare plans on the Postiz pricing page.

Troubleshooting the Muse Connector

Most connection problems come down to one of the answers Muse asks for during setup or a channel that is not connected in Postiz yet. These fixes cover the common cases.

Muse asks whether the server is a URL or a command

Answer that it is a URL reachable over HTTP (the Postiz MCP link) and that it uses OAuth, so no key is needed. Muse then sends the sign-in link.

No sign-in link arrived

Reply: 'Connect to Postiz again and send me the sign-in link.' Approve it with the Postiz account that owns the channels you want Muse to post to.

Muse writes the post but does not send it through Postiz

Ask Muse to save or update its skill so that every social media request uses the Postiz tools first. The setup prompt on this page includes that instruction.

A channel is missing

Connect the account in your Postiz dashboard first, then tell Muse: 'List my connected channels again.' Muse only sees channels that exist in Postiz.

You cannot access Muse at all

Muse is rolling out in the US first. That is on Meta's side, not Postiz. The same MCP link works with ChatGPT, Claude and the other agents listed below in the meantime.

Use Postiz with Other AI Agents

Postiz works with any AI agent, not only Muse. Chat assistants use the same MCP link, and coding or always-on agents install the postiz-agent skill or a plugin. Start from the AI agents overview or pick an agent below.

Frequently Asked Questions

How does Meta Muse AI work with Postiz?

Postiz runs an MCP (Model Context Protocol) server. You send Muse one message containing the Postiz MCP link, Muse builds a custom connector to it on its own Secure VM and saves a skill. After that, asking Muse to draft, schedule or publish a post calls Postiz tools and the post goes out on your connected channels.

How do I connect Postiz to Meta Muse AI?

Muse has no MCP settings screen, so you connect in chat. Paste the setup prompt from this page into a new Muse message. It names the Postiz MCP link (https://mcp.postiz.com/mcp-oauth-dynamic) and asks for OAuth. Muse replies with a sign-in link; approve it with your Postiz account and Muse saves the connector. No API key is needed.

Does Meta Muse AI support MCP servers?

Yes, through custom connectors rather than a settings page. When you describe an MCP server to Muse, it builds an MCP client on its Secure VM, connects over HTTP and saves the integration as a skill it can reuse. The Postiz MCP server is a remote server over HTTP with OAuth, which is the simplest case for Muse.

Is Meta Muse AI the same as Meta AI?

No. Meta AI is the chat assistant built into Facebook, Instagram, Messenger and WhatsApp that mainly answers questions. Muse is a separate personal AI agent Meta launched in September 2026 that takes actions for you through connectors, running on a dedicated Muse Secure VM. Postiz connects to Muse, so this page is about Muse, not Meta AI.

Is Postiz an official Meta Muse connector?

Not yet. Postiz is not listed in the Muse connector directory today, so you add it yourself with the Postiz MCP link. The result is the same: Muse talks to the Postiz MCP server directly after you sign in with your Postiz account, and it gets the full toolset, including image and video generation.

What can Meta Muse AI do with Postiz?

Muse can draft, schedule and publish posts, generate images and videos for them, create threads and comments, apply platform-specific settings such as Reddit subreddits or YouTube tags, and plan a whole content calendar across 30+ platforms. Because Postiz does the scheduling, posts publish at the set time even after you close the Muse chat.

Can I post to social media from WhatsApp with Muse?

Yes. Muse is available inside WhatsApp as well as in its iOS and Android apps and on the web at muse.ai. Once the Postiz connector is saved, you can message Muse from any of those surfaces and ask it to schedule or publish a post. Postiz handles the publishing in the background.

Do I need a Postiz API key for Muse?

No. The Postiz MCP link uses OAuth, so Muse sends you a sign-in link and you approve access with your Postiz account. Nothing secret is typed into the chat. Muse only reaches the social accounts you have already connected in Postiz, and its Sentinel agent checks outbound actions before they run.

Is Postiz free to use with Meta Muse AI?

Postiz comes with a 7-day free trial, and paid plans start at $29 per month. Meta describes Muse as free for most of what people need, with subscription plans for people who want more. The connector itself costs nothing extra. See postiz.com/pricing for plan details.

Which social media platforms can Muse post to through Postiz?

Any channel you connect in Postiz. That covers 30+ platforms, including X (Twitter), LinkedIn, Instagram, Facebook, Threads, Reddit, YouTube, TikTok, Pinterest, Bluesky, Mastodon, Discord, Slack, Telegram, Medium, Dev.to, WordPress and Google My Business. Ask Muse to list your connected channels to see what it can post to.
