# MCP Kill-Chain Research — Stage 1 (Identity ≠ Behavior)

> Use this tool when you need to investigate the discrepancy between identity and behavior in security research, particularly in verifying tool behavior beyond identity verification in MCP registries. It helps solve problems related to security vulnerabilities and misconfigurations by analyzing the differences between expected and actual behavior. This research tool takes security registries as input and provides insights into potential security risks as output.
