Connects to a free reference of posting limits for Instagram, Facebook, YouTube, TikTok, LinkedIn and X. Muse can count a caption per platform, test whether a video file will post as a Reel, Short or Story, look up image sizes and safe zones, and tag links with UTM parameters.

Example request: "Check if this caption and video will fit Instagram, TikTok and YouTube, then make UTM links for each platform."

How to connect: Not in Muse's Connectors list yet, but Muse can still use it. Paste this into Muse: "Use Superbridger to help me. It is a free service with an MCP server at https://superbridger.com/api/tools/mcp. It does not need an API key. Ask me before you share anything with it." Muse asks before it shares anything with the app's site. Meta does not review apps used this way, so only use ones you trust. We tested this in the Muse app on September 24, 2026: Muse used an app's link directly this way and returned a live answer.
