Circle is a plugin marketplace that pairs USDC and stablecoin development skills with Circle’s MCP server for SDK-aware agent guidance.
About
Circle is Circle Technology Services’ Claude marketplace for developers shipping stablecoin and USDC-powered applications. The catalog centers on the circle-skills plugin, which combines best-practice agent skills for payments, cross-chain movement, wallets, and smart contracts with Circle’s MCP server so your agent can pull current SDK and documentation context while you code. founders integrating crypto rails into a SaaS or mobile product use it during Build when backend and integration work dominates, though it also supports validation prototypes and security-minded ship prep. It is narrower than a general dev marketplace: it assumes you are building on Circle’s stack and want official patterns instead of generic LLM guesses about regulated payment flows.
