Cue custom MCP connector OAuth, no API key

Post to Social Media with Cue TikTok, Instagram, YouTube and more, handled by your Cue agent

  • Connect your Cue agent to your social accounts with one message
  • Publish, schedule and read analytics just by asking
  • Turn repeat work into Cue routines, with your approval before anything goes out

Step 1: send this to your Cue agent

Cue setup prompt
Add Upload-Post as a custom MCP connector over HTTP with OAuth:
https://mcp.upload-post.com/mcp

- Setup: it is a standard MCP server over HTTP (a URL, not a command). No API key is needed: send me the sign-in link and I will approve it.
- Use it for every request about posting, scheduling, analytics, comments or DMs on my social media accounts.
- Before you publish, schedule, reply or send a DM, show me the caption, the accounts and the date and time, and wait for my OK.

Once you are connected, list my Upload-Post profiles and the social accounts connected to each.

No API key needed. Sign in to Upload-Post when Cue asks you to approve access.

How to connect Upload-Post to Cue

You set it up in a conversation with your agent. It takes about two minutes.

Step 1

Paste the setup prompt

Copy the prompt above and send it to your Cue agent, on the web, desktop or mobile app. It carries the Upload-Post MCP URL.

Step 2

Confirm URL and OAuth

If Cue asks what kind of server it is, answer that it is a URL (MCP over HTTP) that uses OAuth, not an API key.

Step 3

Approve the sign-in

Open the sign-in link Cue sends you and approve access with your Upload-Post account on app.upload-post.com.

Step 4

Cue lists your profiles

Cue saves the connector and lists your Upload-Post profiles with their connected accounts. From then on, just ask it to post.

One connector per agent: Connectors belong to the agent you add them to. If you run several Cue agents, send the setup prompt to each one that should post for you, or keep social media on a single dedicated agent.

One connection powers every channel

Connect your social accounts to Upload-Post once. Cue can then post to all of them from the same conversation.

What can Cue do with Upload-Post?

Every capability maps to documented Upload-Post tools. Your agent picks the right one from your request.

Just ask in plain language

Tell your Cue agent what to post, where and when. It picks the right Upload-Post tool for the job.

Publish anywhere

Upload videos, photos and text to TikTok, Instagram, YouTube, LinkedIn, Facebook, X, Threads, Pinterest, Reddit, Bluesky and Google Business.

Schedule and queue

"Post this tomorrow at 6pm" becomes a scheduled post. Cue can also add posts to your queue and check their status.

Read analytics

Ask which posts performed best this week and get the numbers from your connected accounts.

Comments and DMs

Read new comments, draft replies and handle direct messages from the same conversation.

Media and FFmpeg

Stage media files and trim, convert or re-encode video with the FFmpeg tools before it goes out.

What is Cue?

Cue is a personal agents app from Manus, launched on September 28, 2026. Instead of only answering questions, a Cue agent does the work: it sends messages, takes calls, books and pays within the limits you set.

  • Each agent can have its own email address, phone number, wallet and computer
  • Connectors link an agent to the services that hold the work, over OAuth or MCP
  • Routines repeat the same steps on a schedule or when something happens
  • You decide what each agent can access and which actions need your approval
  • Several agents can split the work and collaborate in one workspace

What is the Upload-Post MCP?

The Upload-Post MCP is a hosted Model Context Protocol server that gives AI agents your connected social accounts as tools. It is the same server behind our ChatGPT, Claude and Meta Muse integrations.

  • Send your Cue agent the Upload-Post MCP URL in one message
  • Sign in with OAuth 2.1: no API key in the chat
  • Cue discovers your profiles and connected accounts
  • Tools for uploads, status, scheduling and queue, analytics, profiles, pages and boards, comments, DMs, media staging and FFmpeg
  • Open source: github.com/Upload-Post/upload-post-mcp
Cue connector
Type   MCP over HTTP
Name   Upload-Post
URL    https://mcp.upload-post.com/mcp
Auth   OAuth 2.1 (no API key)

What can you ask Cue to post?

No commands to memorize. Just describe what you want.

Cross-post Instagram, TikTok, YouTube

“Post this clip to Reels, TikTok and Shorts tomorrow at 6pm.”

Analytics All connected accounts

“What were my best posts this week?”

Community Your last video

“Reply to new comments on my last video.”

Discover Upload-Post profiles

“List my Upload-Post profiles and the accounts connected to each.”

Run your social media as Cue routines

A routine repeats the same steps for you. With Upload-Post connected, those steps can include publishing, reading analytics and answering comments.

Weekly report

"Every Friday at 4pm, sum up this week's best posts from Upload-Post and send me the numbers."

Morning comment sweep

"Every morning, read new comments on my last three videos and draft replies. Post them only after I approve."

A social media agent

Create a dedicated Cue agent for your channels, connect Upload-Post to it, and keep its work separate from your other agents.

Can Cue post on a schedule?

Yes. Cue hands the schedule to Upload-Post, and Upload-Post publishes each post at the set time whether or not the agent is working on something else.

Batch a week

One request can create several scheduled posts, each with its own date, time and accounts.

Use your queue

Ask Cue to add posts to your Upload-Post queue instead of picking every time by hand.

Check what is queued

Ask what is scheduled and Cue reads it back from Upload-Post, so you can change plans before anything goes out.

Is it safe to let Cue post for you?

The connector uses OAuth, so you approve access with a sign-in link and never paste a key into the chat.

How does Cue compare to other AI assistants?

The same Upload-Post server works everywhere. What changes is how you connect it.

Assistant How you connect Upload-Post Where it runs
Cue One message with the MCP URL; Cue adds it as a custom MCP connector with OAuth Cue on the web, desktop and mobile
Meta Muse One chat message with the MCP URL; Muse builds a custom connector muse.ai, iOS and Android app, WhatsApp
ChatGPT Official Upload-Post app in the ChatGPT directory, or a custom MCP connector chatgpt.com and the ChatGPT apps
Claude Settings, Connectors, Add custom connector with the MCP URL claude.ai and Claude Desktop
Grok Bot Custom MCP connector with OAuth or an API key stored as a Bot secret Always-on Bots on their own cloud computer

Which social media platforms can Cue post to?

Every account you connect in Upload-Post. Each platform has its own guide with formats and rules.

How much does it cost to use Cue with Upload-Post?

The connector costs nothing extra.

Upload-Post connector

Free. The MCP server is open source and works with every Upload-Post plan.

Upload-Post free plan

10 uploads a month, no credit card. TikTok is not included on the free plan.

Cue

Troubleshooting the Cue connector

The five things that usually go wrong, and how to fix them.

Cue asks whether the server is a URL or a command

Answer that it is a URL reachable over HTTP, https://mcp.upload-post.com/mcp, and that it uses OAuth. No API key is needed.

No sign-in link arrived

Reply "Connect to Upload-Post again and send me the sign-in link." Approve it with the Upload-Post account that owns your connected social accounts.

Cue writes the post but does not send it through Upload-Post

Tell Cue to use the Upload-Post connector for every social media request, then repeat the request. Asking it to list your Upload-Post profiles first also helps.

A social account is missing

Connect that account to a profile at app.upload-post.com first, then tell Cue "List my Upload-Post profiles again."

I cannot access Cue yet

Access to Cue is decided by Manus, not by Upload-Post. In the meantime the same MCP server works in Manus, Meta Muse, ChatGPT, Claude and other MCP clients.

Use Upload-Post with other AI agents

One Upload-Post account, the same MCP server, any assistant.

Frequently asked questions

Cue + social media, answered. Last updated September 2026.

How does Cue work with Upload-Post?

Upload-Post runs a hosted MCP server at https://mcp.upload-post.com/mcp. You send your Cue agent one message with that URL, Cue adds it as a custom MCP connector, and you approve access with OAuth. After that the agent can publish, schedule and analyze posts on your connected social accounts.

How do I connect Upload-Post to Cue?

Paste the setup prompt from this page into a conversation with your Cue agent, confirm it is a URL with OAuth if asked, and open the sign-in link Cue sends you. It takes about two minutes.

Is Upload-Post a built-in Cue connector?

No. Cue connects to any MCP server, so you add Upload-Post yourself as a custom MCP connector with the setup prompt on this page.

Do I need an Upload-Post API key for Cue?

No. The connector uses OAuth 2.1: Cue sends you a sign-in link and you approve access with your Upload-Post account at app.upload-post.com.

Can a Cue routine post to social media for me?

Yes. Once the connector is set up, any routine on that agent can call Upload-Post: a weekly analytics summary, a daily comment sweep or a batch of scheduled posts. Keep approval on for publishing so the agent checks with you first.

Does the same setup work in Manus?

Yes. Cue is built by Manus, and Manus takes the same server: open Settings, Integrations, Custom MCP Servers, choose Add Server and enter https://mcp.upload-post.com/mcp.

Which social media platforms can Cue post to?

Any account you connect in Upload-Post: TikTok, Instagram, YouTube, LinkedIn, Facebook, X, Threads, Pinterest, Reddit, Bluesky and Google Business.

Is it free?

The connector is free. The Upload-Post free plan includes 10 uploads a month with no credit card; TikTok is not included on the free plan. Cue itself is a Manus product with its own access and plans.
