## Description

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.

## Why it scored 40

The score starts at the catalog's neutral base of 50 and moves only through the signals below. The formula is published at https://catalog.anomity.ai/about — there is no model and no hidden heuristic.

| Signal | Contribution | Severity | Evidence |
| --- | --- | --- | --- |
| Established community project | -10 | trust offset |  |

Clamped result: **40/100**, band **medium**.

## Capabilities

| Capability | Name | Security implication |
| --- | --- | --- |
| `browser:control` | Browser control | Drives a browser session. Combined with credential access can impersonate the user on web services. |
| `network:outbound` | Outbound network | Can make outbound network requests. Required for hosted model providers and remote APIs; also the path for data exfiltration if combined with read access. |
