Manus lists the tools

Manus verifies the connection and lists the Upload-Post tools. Start a task with the prompt below and ask it to post.

Manus first-task prompt
You are connected to the Upload-Post MCP server
(https://mcp.upload-post.com/mcp). Follow these rules:

1. Use it for every request about posting, scheduling, analytics, comments or DMs on my social media accounts.
2. Only use tools the server actually exposes. Never invent tool names or parameters.
3. Confirm the connection with a read-only call: list my Upload-Post profiles and the accounts connected to each.
4. Before publishing, scheduling, replying or sending a DM, show me the caption, the target accounts and the date and time (with timezone), and wait for my approval.
5. After publishing, check the upload status and report the result for each platform.

Setup details, tool reference and auth options are in the MCP server docs. The server is open source: Upload-Post/upload-post-mcp.

Using Cue? Cue, the personal agents app from Manus, connects to the same server with a single message. See how to post to social media with Cue.

One connection powers every channel

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

What can Manus do with Upload-Post?

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

Just ask in plain language

Tell Manus 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. Manus 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 task.

Media and FFmpeg

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

What is Manus?

Manus is a general AI agent. You give it a goal and it works through the steps on its own: researching, writing and creating files until the task is done. With Upload-Post connected, publishing and scheduling can be the last step of that task.

  • A general AI agent at manus.im that works through long, multi-step tasks
  • Manus 2.0 launched on September 28, 2026, together with the Cue app
  • Connects to outside tools through Custom MCP Servers in Settings, Integrations
  • Verifies each MCP server when you add it and lists the tools it offers

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 Cue integrations.

  • Add the Upload-Post MCP URL once in Manus settings
  • Sign in with OAuth 2.1, or use an ApiKey header
  • Manus 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
Manus connector
Type   Custom MCP server (HTTP)
Name   Upload-Post
URL    https://mcp.upload-post.com/mcp
Auth   OAuth 2.1, or Authorization: ApiKey YOUR_API_KEY

What can you ask Manus 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?”

Research LinkedIn, X

“Research what changed in our industry this week, write a LinkedIn post and an X thread, and schedule both for Monday at 9am.”

Discover Upload-Post profiles

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

From a long Manus task to a published post

Manus does the multi-step work. Upload-Post takes the result and gets it onto your accounts.

Research, then post

"Find the three most discussed topics in my niche this week, draft a post for each and schedule them across the week through Upload-Post."

Create, then publish

Manus can create images, slides and other assets as part of a task. Ask it to hand the finished files to Upload-Post and post them to the accounts you pick.

Report on results

"Pull last month's numbers from Upload-Post, compare them with the month before and write me a short report with what to post more of."

Can Manus post on a schedule?

Yes. Manus hands the schedule to Upload-Post, and Upload-Post publishes each post at the set time, long after the task has finished.

Batch a week

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

Use your queue

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

Check what is queued

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

Is it safe to let Manus post for you?

You approve access with OAuth, and the first-task prompt tells Manus to check with you before anything goes out.

How does Manus compare to other AI agents?

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

Agent How you connect Upload-Post Where it runs
Manus Settings, Integrations, Custom MCP Servers, Add Server; OAuth or an ApiKey header manus.im
Cue One message with the MCP URL; Cue adds it as a custom MCP connector with OAuth Cue on the web, desktop and mobile
Perplexity Computer Custom connector in Settings, Connectors with the MCP URL; OAuth or API key Perplexity cloud agent on Pro, Max and Enterprise
Genspark Tools icon in a Super Agent chat, Add new MCP server with an ApiKey header Genspark Super Agent
Claude Cowork Add a custom connector in Claude, then use it in Cowork tasks Claude Desktop on macOS and Windows; beta on web and mobile

Which social media platforms can Manus 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 Manus with Upload-Post?

The connector costs nothing extra.

Upload-Post connector

Troubleshooting the Manus connector

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

Manus cannot verify the server

Check that the URL is exactly https://mcp.upload-post.com/mcp and that you finished the OAuth sign-in. If you used a header, it must read Authorization: ApiKey YOUR_API_KEY.

The OAuth sign-in window did not open

Allow pop-ups for Manus and try again, then approve access with the Upload-Post account that owns your connected social accounts. The API key header is the fallback.

Manus finishes the task but does not publish

Tell Manus to use the Upload-Post MCP server for every social media request, then repeat the task. 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 ask Manus "List my Upload-Post profiles again."

A large video fails to upload

Ask Manus to stage the file with the Upload-Post media tools first, or to re-encode it with the FFmpeg tools. Each platform guide lists its size and length limits.

Use Upload-Post with other AI agents

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