Rainbrand – Brand Layer for AI Agents via MCP and API

Description

Rainbrand is a brand layer for AI agents. It turns brand guides, websites, logos, fonts and voice notes into shared context that Claude, ChatGPT, Codex, Cursor and similar tools can use through MCP, plugins and an API. Instead of pasting a style guide into every chat, your agents pull a living brand object when they brief work or review finished copy and creative.

Rainbrand launched on Product Hunt around 5 November 2026 with roughly 108 upvotes, positioning itself as the missing brand system for agent workflows. Teams such as Revnu and Autumn are among early users. The product centres on two jobs: Briefs that steer a task so the output starts on-brand, and Reviews that score finished AI output against your brand and say what to fix.

Who Rainbrand Is For

Rainbrand suits teams that already lean on AI for content and design, but keep losing brand consistency:

• Brand and content leads who want every Claude or ChatGPT draft to follow the same voice and visual rules.
• Agencies managing several client brands for the same set of agents.
• Product and growth teams shipping AI-generated assets that still need a compliance pass.
• Builders wiring brand context into agent stacks via MCP or the Rainbrand API.

Core Capabilities

Shared Brand Context

Rainbrand builds a brand from a website, brand guide or uploaded files, capturing colours, fonts, logos and voice. That object is then available to your agents and products so prompts do not start from a blank slate every time.

Briefs for On-Brand Tasks

An asset brief (100 credits) guides one piece of work, or you can generate 2K or 4K images (100 or 200 credits). The brief is meant to steer the agent before it writes or designs, reducing rework later.

Reviews for Brand Compliance

A review (200 credits) checks finished copy or creative against the brand and lists what to fix. Brand edits (300 credits) update guidance such as new colours or tone; applying or discarding the edit is free once the proposal is ready.

MCP, Plugins and API on Every Plan

API and MCP access are included on every paid plan, and the signup grant is enough to create one brand and try the flow. Agents that run out of credits mid-task stop cleanly and link back to top-up rather than failing silently.
