Context Firewalls Become Mandatory
Projection: A2A expands the message surface between agents, while current MCP servers expand the content and services they can reach. That combination calls for a context firewall separating trusted instructions from retrieved material, tool output, and peer messages. Its test is containment of adversarial content without breaking legitimate coordination.
Why this idea is here
What the evidence establishes.
Google Cloud adds current MCP servers connecting agents to cloud data and services through a standard interface; The A2A community releases v1.0 as a stable, production-ready agent-interoperability standard that complements tool-and-context protocols. These are source-backed premises for this inference; they do not by themselves prove broad adoption or the eventual outcome.
