Analysis summary

Model Context Tool Inspector is a community-maintained WebMCP tool from Beaufort. Anomity scores its risk at 40 out of 100 (medium).

A Chrome extension that discovers the WebMCP tools a page registers, renders their JSON schemas, and lets you invoke them manually with arguments you choose. Where WebMCP Radar answers "what is here", the Inspector answers "what happens when it runs".

Manual invocation is exactly what makes it useful for review and exactly what makes it sharp. Calling a tool from the Inspector executes it in the live page, in the live session — a `checkout` or `deleteAccount` tool does the real thing. It declares browser control and outbound network access. Use it against staging, or against accounts you are willing to mutate, and treat every successful invocation as evidence of what a compromised agent could have done unattended.
