A new system called MCP (Message Capability Protocol) has been introduced to provide granular control over AI sub-agent permissions, addressing the security risks of agents having access to parent credentials. MCP allows developers to set specific budgets for sub-agents, limiting their access to tools, usage counts, and duration. This system uses cryptographic signing and a public registry contract on the Base blockchain for verification, eliminating the need for a central authorization server and enabling real-time revocation of agent capabilities.
