Your brand guidelines, read and changed by your own tools
Melon Cut keeps your brand guidelines, and the Melon Cut API and MCP server let your own tools use them: read a brand's colours, fonts and logos, change a brand through a draft you can see on meloncut.com before it is live, and publish it - with a key of your own, for your brands on the Business or Enterprise plan.

Brand API and MCP server, step by step
Make a key
In Melon Cut Guidelines, open API keys and make one. It is shown once, reaches your brands on the Business or Enterprise plan, and can be revoked at any time.
Connect
Call https://api.meloncut.com/v1 with the key as a bearer token, or add the MCP server at https://api.meloncut.com/mcp to Claude Code, Claude Desktop, Cursor or VS Code.
Read, draft and publish
Read a brand's guidelines, start a draft, change it, look at it on meloncut.com, then publish it over the brand or create a new brand from it.
What your tools can do
Everything the API does, the MCP server does too, for the same person and with the same rules: a tool is the route it calls.
- List your brands, with their plans and addresses
- Read a brand whole: colours, fonts, images, systems, foundation, guideline sections and models
- Read a brand's brief for a deliverable - a social media post, a website, copy
- Search the public brands in the Melon Cut directory, and check whether a username is free
- Start a draft: a new brand, one of yours to edit, or one of yours to start a new brand from
- Change a draft by operations, upload pictures and fonts to it, and undo
- Publish a draft over its brand, as the brand's new identity or as an earlier one, or create a brand from it
Drafts you see before they are live
Every change goes into a draft, checked by the same guideline rules as the Guidelines editor. Each draft has a private preview address on meloncut.com that shows it exactly as publishing it would, and is never listed or indexed.
Publishing is refused when the brand was changed in Melon Cut since the draft began, so nobody's work is written over, and a draft can be handed to Melon Cut Guidelines to finish by hand.
Cutlin works with every plan
Cutlin, the separate AI studio that follows Melon Cut guidelines, is Melon Cut's partner: it reads and changes your brands through this same API on every plan, Free included, with nothing to set up.
Keys and limits
A key is yours: it reaches only your own brands on Business or Enterprise, it is kept only as a fingerprint, and you can revoke it whenever you like. A key makes up to 60 requests a minute on Business and 600 on Enterprise.
