Circle Agent Stack Mcp

Wraps Circle's Agent Stack so Claude can create USDC wallets, set spending policies, transfer funds, and pay x402 endpoints that bill per call in stablecoin. You get six tools: wallet creation and listing, balance checks, policy management, standard USDC transfers, and x402 payments that return the API response along with the amount paid. Currently shells out to the Circle CLI for auth and operations, with direct SDK support planned for v0.2. Worth looking at if you're building agents that need to handle crypto payments autonomously or consume APIs that charge in USDC instead of requiring API keys. Start with dev wallets and set daily caps before you point it at anything live.
