Overview

AI-generated overview

Lets an assistant plan marketing campaigns, draft on-brand posts, and schedule them after explicit approval.

What it does
Rebbel is a remote MCP server for small-business marketing. Its tools cover setting up a brand from a website URL, generating and approving a brand guide (identity, voice, colors, audience) and a strategy (channel mix, cadence, budget split), then generating campaigns and posts, listing and approving them, and scheduling approved posts. A results tool gives a plain-English read on campaign performance.
When to use it
Use it when a small business wants an assistant to draft and organize social or marketing content around a defined brand and strategy, with a human approval step before anything goes out. It is less useful if you only need one-off copywriting with no brand setup or scheduling.
Requirements
A remote MCP endpoint reached over streamable HTTP, with OAuth 2.1 sign-in and dynamic client registration; no API key or environment variable is declared. The client must support remote streamable HTTP plus OAuth. Sign-in is prompted the first time a Rebbel tool is used.
Before you install
The server can create and change brand, strategy, campaign, and post data, and schedule posts; publishing and spending are gated behind explicit approval enforced on the server. Sign-in grants access to your Rebbel account, and brand setup may take a website URL as input. Review the privacy policy before connecting.

What it can do

  • list_brands / create_brand — set up a brand from a website URL
  • generate_brand_guide / approve_brand_guide — identity, voice, colors, audience
  • generate_strategy / approve_strategy — channel mix, cadence, budget split
  • generate_campaign / create_post / list_posts / approve_post — draft and review posts
  • schedule_post — schedule an approved post (refuses anything not approved first)

Approval, always

Rebbel never publishes a post or spends a dollar without your explicit approval — enforced on the server, not just in the UI. See the Privacy Policy.
