Carbon MCP

ClaudeCommunityby IBM

AI assistants are good guessers. When you ask one for Carbon code, it fills gaps with whatever it learned during training, which might be a version or two out of date. You end up with components that almost work, props that don't exist anymore, and tokens that look right but aren't. Carbon MCP fixes that by giving your assistant a live connection to IBM's Carbon Design System. It pulls real component source, props, variants, tokens, and icons straight from Carbon for both React and Web Components, so the code it writes matches what's actually shipping. It's also useful for questions, not just code. Ask about when to use a Modal versus a full page, or how spacing tokens should work together, and you get an answer sourced from current Carbon guidance instead of a confident guess. Carbon MCP can also audit code you already have, checking it against Carbon's design and accessibility rules. It catches things like a missing label, the wrong token, or a component used in a way Carbon doesn't recommend, so you find out before a reviewer does. If your team builds on IBM's Carbon Design System, this closes the gap between what your AI assistant knows and what Carbon actually looks like right now.
