install / how to use

install in grok bot
  1. 01 Create a Post Bridge account at post-bridge.com and connect the accounts or data you want it to reach.
  2. 02 Get your API key or MCP connection from your Post Bridge dashboard (see the linked docs for the exact place).
  3. 03 Paste the prompt below into your Grok Bot and give it your Post Bridge key so this becomes a standing capability.

What it does

Post Bridge is one API for publishing and scheduling across 10+ networks — Instagram, TikTok, YouTube, X, LinkedIn and more. It ships a native MCP server and an agent mode so a Grok Bot can upload media and cross-post from a single call.

Use it in Grok Bot

Paste the prompt on this page into a Grok Bot and give it a Post Bridge API key or MCP connection. The bot reads Post Bridge’s own documentation first, wires up the integration, and from then on you drive Post Bridge in plain language — it follows the docs and checks with you before anything that writes or spends.

prompt
You are setting up a Post Bridge integration for me inside Grok Bot. First, read Post Bridge's API reference at https://api.post-bridge.com/reference (and its MCP guide at https://www.post-bridge.com/mcp) so you understand its authentication and the endpoints for uploading media, creating posts, scheduling, and reading analytics, plus which of the 10+ platforms each supports. Then use my Post Bridge API key so that whenever I ask you to cross-post or schedule to my social accounts — Instagram, TikTok, YouTube, X, LinkedIn and the rest — you upload any media and create the post through Post Bridge at the time I specify. Rules: follow the docs exactly, never invent an endpoint or field, and if a platform does not support what I asked, say so. Show me the caption, target platforms, and schedule before publishing, and confirm access first with a read-only call such as listing my connected accounts.
then paste it into Grok

Copy the prompt and paste it into Grok.
