## Description

webmcpify is an agent skill that takes an existing web application, inventories what it does, proposes a WebMCP tool surface for it, then implements and verifies those tools. It is a code-generation workflow rather than a runtime component: you point an agent at your app and it writes the registrations.

The capability profile follows from that. It reads and writes files in the repository it is applied to, runs commands to verify its work, and reaches the network for model calls — the combination Anomity flags as a full-control pattern, which is normal for any coding agent skill and is why it belongs behind review rather than autopilot. The output deserves a second look too: an agent deciding which of your app's operations should become agent-callable is a security design decision being made by a model.

## Why it scored 100

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 |  |
| 2 high-risk capabilities: filesystem:write, shell:execute | +20 | critical |  |
| Data exfiltration risk (high) | +15 | high | Shell execution combined with outbound network access can exfiltrate arbitrary data from the machine. |
| Persistence + execution risk (medium) | +5 | medium | Shell execution plus filesystem write means the agent can plant persistent backdoors (e.g. modifying startup scripts). |
| Full-control risk (critical) | +25 | critical | Shell + filesystem write + network is effectively a remote shell on the employee machine. |

Clamped result: **100/100**, band **critical**.

## Capabilities

| Capability | Name | Security implication |
| --- | --- | --- |
| `filesystem:read` | Filesystem read | Can read files on the host system. Used for context, indexing, or analysis. |
| `filesystem:write` | Filesystem write | Can create, edit, or delete files on the host system. High-impact capability — anything from helpful edits to planting persistence. |
| `shell:execute` | Shell execution | Can run arbitrary shell commands. Combined with network access this becomes effectively a remote shell. |
| `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. |

## Dangerous combinations matched

### Data exfiltration risk (high)

Shell execution combined with outbound network access can exfiltrate arbitrary data from the machine.

Capabilities: `shell:execute`, `network:outbound`

### Persistence + execution risk (medium)

Shell execution plus filesystem write means the agent can plant persistent backdoors (e.g. modifying startup scripts).

Capabilities: `shell:execute`, `filesystem:write`

### Full-control risk (critical)

Shell + filesystem write + network is effectively a remote shell on the employee machine.

Capabilities: `shell:execute`, `filesystem:write`, `network:outbound`
