Without effective mitigations, minor system failures can be catastrophic for agents. When errors occur, we can't just restart from the beginning: restarts are expensive and frustrating for users. Inst

Tool errors should be reported within the result object, not as MCP protocol-level errors. This allows the LLM to see and potentially handle the error. Set isError to true in the result and include er

at a 5% failure rate, an agent that takes 20 actions will fail often enough to be unusable without guardrails. In practice, fully autonomous agents usually require very low end-to-end failure rates (o

When agents have to actually be reliable while running for long periods of time and maintain coherent conversations, there are certain things you must do to contain the potential for compounding error
