circle-skills is a plugin that bundles best-practice "skills" for building Circle-based onchain applications, covering USDC payments, cross-chain transfers, wallets, and smart contracts, according to its README. It also ships an mcp.json MCP server configuration that provides real-time guidance from Circle's documentation. The README lists 17 individual skills, ranging from agent-to-agent USDC micropayments to Circle CLI wallet management and token swaps. The homepage describes Circle itself as a full-stack platform offering USDC, EURC, payment network, wallet, and smart-contract infrastructure. The plugin is aimed at developers (and AI agents working alongside them) who build on Circle's stack.
