## Description

WebMCP Radar is a Chrome extension that detects whether the page you are on registers WebMCP tools, shows how many, and lets you inspect each tool's name, description, and input schema. It is the quickest way to answer "does this site expose an agent surface, and what can it do?" without reading the page's JavaScript.

For a security reviewer it is a discovery instrument rather than an attack surface: it reads what the page has already published. Its capability profile is browser control — it operates inside pages you visit — plus outbound network access. The interesting output is the finding, not the tool: a commerce or banking page that quietly registers state-changing tools is a materially different risk than one exposing read-only search, and Radar is how you tell the two apart before an agent ever touches them.

## Why it scored 10

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 |
| --- | --- | --- | --- |
| Published by the vendor | -40 | trust offset |  |

Clamped result: **10/100**, band **low**.

## 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. |
