presign-guard-wallet-mcp

An MCP server providing an agent wallet with spending limits and phone approvals for AI agents. It allows agents to pay for x402 APIs and send USDC on networks like Base, Solana, Algorand, and XRPL within user-defined budgets, while checking every signature against drainers and sanctioned addresses via presign-guard.
