install / how to use

install in grok bot
  1. 01 Create a MediaFast account at mediafa.st and set up your product's project so it can build your roadmap.
  2. 02 Generate an API key in Settings → API Keys (shown once), or connect the MCP server at api.mediafa.st/mcp.
  3. 03 Paste the prompt below into your Grok Bot and give it your MediaFast key so Reddit marketing becomes a standing capability.

What it does

MediaFast turns your product into a day-by-day Reddit action plan — which subreddits, when to comment, when to post, and what to say, paced to keep your account safe from bans. Its MCP server lets a Grok Bot pull the roadmap, draft subreddit-native posts, and check shadowban status on demand; X, LinkedIn and Bluesky are covered too.

Use it in Grok Bot

Paste the prompt on this page into a Grok Bot and give it a MediaFast API key or the MCP connection. The bot reads MediaFast’s own documentation first, then you drive your Reddit marketing in plain language — it pulls the real roadmap, drafts to each community’s tone and rules, and never posts anything without your go-ahead.

prompt
You are setting up a MediaFast integration for me inside Grok Bot. First, read MediaFast's documentation at https://www.mediafa.st/documentation so you understand its MCP server (https://api.mediafa.st/mcp, API-key auth from Settings → API Keys) and what it does: it turns a product into a day-by-day Reddit action plan — finding the right subreddits, generating subreddit-native post and comment drafts, checking shadowban status, and pacing everything to keep the account safe, with X, LinkedIn and Bluesky supported too. Then connect to my MediaFast account so that when I ask about my marketing plan you pull the real roadmap, when I need a post you draft it native to the target subreddit's tone and rules, and when I worry about account health you check the shadowban status. Rules: follow the documentation exactly and never invent a subreddit, a task, or a metric MediaFast does not return. Account safety is the whole point — NEVER post, comment, or schedule anything without showing me the draft and target first and getting my explicit go-ahead. Confirm the connection by pulling my current roadmap.
then paste it into Grok
