A2AWall

Overview

A2AWall keeps baseline A2A discovery and transport intact while adding security controls around request admission and runtime behavior.

• Agent Card, JSON-RPC, and REST support for standard A2A clients
• Admission control for identity, capability, scopes, trust tier, approvals, and size limits
• Trusted context boundaries for system, user, retrieval, memory, tool, and peer-agent input
• Sandbox and runtime policy evaluation for tools and actions
• Memory, retrieval, delegation, and output validation foundations
