Developers
Everything on this site — 5,299 colours from 14 UK paint brands (plus RAL Classic and BS 4800), cross-brand CIEDE2000 matching, prices, finish specs, the paint planner, and market trends — is available programmatically: as an MCP server for AI tools (Claude, ChatGPT, Cursor…) and as a REST API for software.

MCP server
Endpoint:
OAuth sign-in happens automatically when you connect — no keys to manage. Your AI tool must be able to add a connector: Claude's free plan allows one custom connector, ChatGPT needs a paid plan with developer mode, Cursor works on its free plan. Connect on our Free tier first and upgrade once it works.
Claude (desktop or web): Settings → Connectors → Add custom connector → paste the URL.
Claude Code:
ChatGPT: Settings → Connectors (developer mode) → add the URL. Cursor: Settings → MCP → add server with the URL.
21 tools: colour search and lookup, hex→paint matching, cross-brand comparison, cheapest-equivalent analysis, RAL/BS 4800 lookups, finish specs, saved palettes, planner projects (a conversation becomes a costed shopping list at a share link), and market data (trends, rankings, range changes).
