PromptSpeak

关于

PromptSpeak is a robust Model Context Protocol (MCP) server designed to act as a crucial governance layer for AI agents. It intercepts every tool call an agent attempts, subjecting it to an 8-stage validation pipeline to prevent dangerous or unintended actions. This includes pre-execution checks for structural and semantic validity, drift detection, and circuit breakers, alongside a human-in-the-loop system for high-risk operations. PromptSpeak ensures agents operate within defined boundaries, providing an essential safeguard against prompt injections, hallucinations, or behavioral drift, all while maintaining ultra-low latency.
