AgentWallet MCP Server

Permissionless EVM wallet infrastructure for AI agents. Create wallets, sign transactions, and broadcast on-chain — on any EVM chain.

No KYC. No KYT. No transaction monitoring. No one can block your wallet.

Features

• 20 MCP tools — create wallets, send transactions, approve tokens, wrap ETH, check balances, and more
• 9 EVM chains — Ethereum, Base, Polygon, BSC, Arbitrum, Optimism, Avalanche, Zora, PulseChain
• Secure — Private keys encrypted at rest (Sodium XSalsa20-Poly1305), decrypted only during signing, zeroed from memory immediately after
• Permissionless — No identity verification, no compliance gatekeeping. Create a wallet and transact immediately.

Pricing

• $0.0069 per transaction (31% less expensive than Coinbase CDP)
