Quarantine untrusted tool output behind a powerless dual-LLM boundary
Christian Schneider's defense-first MCP architecture applies the dual-LLM/quarantine pattern: route untrusted tool output through a 'quarantined' model that can parse and summarize but has no authority to take actions, and never let raw tool text re-enter the privileged agent's instruction stream. This structurally blocks tool-poisoning and injected-instruction attacks that content filtering alone misses. If your agent reads web pages, tickets, or third-party MCP results, isolate that content behind a capability boundary.
