ChatGPT and Cursor

ChatGPT: Settings → Connectors (developer mode) → add the URL.
Cursor: Settings → MCP → add server with the URL.

Your AI tool needs to support connectors: Claude’s free plan allows one, ChatGPT needs a paid plan with developer mode, Cursor works on its free plan.

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).
