Latest change

MCPHallu (Nov 5) benchmarks reasoning, execution, and memory hallucinations in MCP agents, shifting the thread from proposed harnesses to measured failure modes.

Earlier contextThe story so far

Two October papers treated the gap between an agent's reasoning and its tool execution as a design surface: speculative execution to cut voice-agent latency, and a Petri-net supervisor to block unsafe calls. A November benchmark then measured where MCP agents fail across that gap.

What to watch — open questions

  • Do speculative tool calls in voice agents hold up when the user revises the request mid-sentence?
  • Does the Petri-net harness add measurable latency or block legitimate calls in real MCP deployments?
  • Which MCPHallu failure category (reasoning, execution, memory) dominates across current models?
