Fuxux for Cue & Manus

Set it up in about two minutes

1. 1

   Create a Fuxux API key

   Sign in to Fuxux, connect the social accounts you want the agent to use, then create a key on the API keys page (keys come with the API add-on, $5/month on any paid plan). It starts with fx_live_. Treat it like a password.

2. 2

   Add a custom MCP connector

   In Manus, open Connectors, click Create, then Custom MCP. Cue runs on your Manus account, so it can use the same connector. Fill in:

   Server Name

   Fuxux

   Transport Type

   HTTP

   Server URL

   https://www.fuxux.com/api/mcp

   Header name

   Authorization

   Header value

   Bearer fx_live_your_key_here

   Keep the space after Bearer. For the icon, choose Upload from device and use the Fuxux icon.

3. 3

   Paste this into the Note field

   The note tells the agent when to reach for Fuxux and keeps it from checking a post every few seconds.

   Fuxux is the user's social media scheduler. Use it to create, schedule and publish posts to 14 platforms (Instagram, TikTok, YouTube, X, Facebook, LinkedIn, Threads, Pinterest, Bluesky, Reddit, Discord, Google Business Profile, Twitch, Kick), list connected accounts, and check the post queue. Call whoami first. Check a post's status at most once a minute; never poll in a tight loop.

4. 4

   Save and try it out

   Click Save, then Try it out and ask something read-only first, like "call whoami and list my connected accounts". If it answers with your email and accounts, you're connected.

Things to ask your agent

• “Show my 5 most recent Fuxux posts and which ones failed.”
• “Turn this blog post into a LinkedIn post and an X post, and save both as drafts in Fuxux.”
• “Schedule this caption to Instagram and Threads for tomorrow at 9am my time.”
• “What's in my Fuxux queue for next week?”
