Rebbel for Claude, Cursor, and Gemini CLI

Run your AI marketing department from chat. Connect Rebbel to your assistant and generate brand guides, strategy, and full campaigns without leaving the conversation — every asset and every scheduled post still goes through your approval first.

What is MCP?

MCP (Model Context Protocol) is the open standard that lets AI assistants like Claude, Cursor, and Gemini CLI securely use external tools — Rebbel is one of them. You chat (“draft next month’s content for my bakery”), Rebbel does the marketing work, and you stay the approver the whole way through: nothing publishes or spends without you saying yes.

Claude

  1. In Claude, add a connector for app.rebbel.io, or search for “Rebbel” in Claude’s Connectors Directory if it’s listed there for your account — either way lands you at the same sign-in.
  2. Sign in (or create a free account — no credit card required) when prompted. Claude handles the OAuth exchange automatically.
  3. Start asking Claude to work on your brand’s marketing — see example prompts below.

Free to start: every new account gets a monthly generation allowance to try a full campaign end to end, no card on file.

Don’t have a Facebook Page or linked Instagram yet? See the setup guides.

Cursor

Add this to .cursor/mcp.json (project) or ~/.cursor/mcp.json (global) — Cursor handles the OAuth sign-in automatically:

{
  "mcpServers": {
    "rebbel": {
      "url": "https://app.rebbel.io/api/mcp"
    }
  }
}

Gemini CLI

Add this to ~/.gemini/settings.json:

{
  "mcpServers": {
    "rebbel": {
      "httpUrl": "https://app.rebbel.io/api/mcp",
      "oauth": { "enabled": true }
    }
  }
}

Example prompts

  • “Set up a new brand for [my business] from [website URL] — no card needed to try it.”

  • “Generate a strategy for [Brand] — our goal is [goal], budget is $[X]/month.”
  • “Plan and draft next month's Instagram content for my bakery — I'll approve before anything posts.”

Recipes

Copy-paste these, or use the matching prompt from Claude’s prompt picker (search “rebbel”) — same golden paths, one click instead of a paragraph. The last two turn into a standing autopilot if your assistant supports recurring/scheduled tasks: Rebbel drafts on schedule, you still approve everything before it ships.

  • Set up a new brand

    “Set up a new brand for [my business] from [website URL].”

  • Get my first post live

    “I want to see Rebbel actually post something for real, fast — help me connect a social account and draft a first post.”

  • Launch a campaign

    “Generate a new campaign for [Brand] to promote [what you're promoting] — angle: [hook].”

  • Write more posts

    “Write another batch of draft posts for [Brand]'s [campaign] campaign.”

  • Weekly drafting cadence (scheduled task)

    “Every Monday morning, draft this week's posts for [Brand] and show them to me for approval. Set this up as a recurring task if your assistant supports scheduling (e.g. Claude's Tasks) — it's a free autopilot for drafting, approval still stays with you.”

  • Weekly results check-in (scheduled task)

    “Every Monday, check last week's results for [Brand] and give me a plain-English summary of what's working. Set this up as a recurring task if your assistant supports scheduling (e.g. Claude's Tasks).”

Trust & safety

  • Approval on everything.No post publishes and no ad spend is ever recommended without your explicit approval — enforced server-side, not just hidden behind a UI. No path, including through Claude, skips it.
  • OAuth 2.1, not a shared password.Rebbel never sees your Claude account credentials, and you can revoke access anytime from your assistant’s connector settings.
  • Your accounts stay yours. Rebbel publishes only to social channels you connect with your own login, and you can disconnect any channel anytime.
  • Free tier is the real trial.No card required to run a full brand guide → strategy → campaign loop end to end.
  • Not seeing the newest tools?Claude caches a connector’s tool list from when you first connected — a fresh conversation alone doesn’t refresh it. Disconnect and reconnect the Rebbel connector to pick up new tools.
