Perplexity

2. + Custom connector → Remote.
3. MCP server URL: https://app.rebbel.io/api/mcp
4. Under Advanced: Transport Streamable HTTP, Authentication OAuth 2.0 (leave Client ID/Secret blank — Rebbel supports OAuth discovery + dynamic client registration).

Slack

Install the Rebbel Slack app to your workspace (App Directory listing pending). Approve posts from the channel — same server-enforced approval gate as every other surface. Setup guide: rebbel.io/mcp/slack.

Generic remote MCP config

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

Works with Windsurf (~/.codeium/windsurf/mcp_config.json), VS Code MCP extensions, and any client that supports remote streamable HTTP + OAuth.

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)
• get_results_verdict — plain-English campaign performance read

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.
