mcp 0.5.0 - agent ignores tool errors and continues execution with stale data
tool returns error, agent just uses last successful output from 3 calls ago. tested on weather tool that fails randomly - agent hallucinates current weather from cached response.

need exponential backoff badly for our agent deployment. manually patched it but shouldn't be necessary

we saw this exact behavior in our deployment on mcp 0.5.0 last week. tool fails with 404, agent retries with identical params 23 times before we killed it manually. no exponential backoff, no circuit breaker logic at all. tested with llama 3.3 70b and tool execution timeout set to 30s - each retry waited full 30s before trying again

23 retries with identical params.... zero backoff.... production code....
