Locker Overview

The locker MCP server provides wallet-addressed mailbox and storage capabilities for AI agents. Sending requires payment through x402, while reading is free when the requester has the relevant key. Reach for it when agents need an addressable way to exchange or retrieve messages and stored data, but verify deployment and client details separately because the README is unavailable.
