Agent Output Guard
by agenson-horrowitzcommunityv1.0.8
This MCP server addresses coordination failures in multi-agent systems by providing validation tools to ensure reliable data handoffs between agents. It operates without the costs associated with language model APIs.
From the registry: Validate and verify data from other agents before acting on it. Zero LLM costs.
