Circle-skills is a Claude Code plugin that packages a set of skills together with an MCP server configuration for building on Circle's stablecoin infrastructure. According to the README, it covers everyday development tasks such as checking balances and sending USDC on EVM chains and Solana, bridging tokens between chains with Circle's CCTP protocol, choosing and configuring different wallet models, deploying smart contracts, and setting up agent-to-agent USDC payments. The bundled MCP server connects the assistant to Circle's documentation so it can reference SDK details while working. Rather than writing integration code from scratch, developers get a repeatable, guided path for common stablecoin payment and wallet workflows.

About the service

Circle is the company behind the USDC and EURC stablecoins. Per the circle-skills homepage source, it operates a broader platform of payment, wallet, and blockchain infrastructure — including Circle Payments Network, Circle Wallets, the CCTP cross-chain transfer protocol, a smart contract platform, and its own blockchain called Arc — that developers can access through APIs and SDKs.

  • Deploy and interact with smart contracts via Circle's Smart Contract Platform
  • Build applications on Arc, Circle's blockchain that uses USDC as native gas
  • Use the Circle CLI to create, fund, and set spending policies for agent wallets
