## Findings

- **high** References to secrets on disk in `check_exposed_files` ([sensitive-path](https://anlyon.dev/methodology#sensitive-path))

```untrusted-server-text
The description refers to ".env".

description: "...r accidentally exposed high-risk files (.env, .git/config, backups, etc.). Reports H..."
```


## Can't be undone (1)

Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask.

### `scan_local_code`

- The description's first verb is "send": a word for sending, and what is sent cannot be taken back.

Description, as the server wrote it:

```untrusted-server-text
Send selected editor file contents to the SimplyScan Security Engine's deterministic repository rules. Requires a Pro API key. Source leaves the editor, is processed in memory, and is not retained; masked findings are saved in the private scan record. No AI provider receives these files. Code rules analyse JavaScript and TypeScript; other files are checked for secrets only. When no file can be analysed, the result has no score.
```

## Changes things (6)

Creates or changes something that can be changed back. Claude Code: ask.

### `check_ai_visibility`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
AEO check: whether AI answer engines (ChatGPT/GPTBot, Claude, Perplexity, Google-Extended, etc.) can crawl and cite the site, plus llms.txt and structured-data signals.
```

### `check_email_security`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Check a domain's email authentication: SPF, DKIM (common selectors), and DMARC policy. Flags spoofable domains.
```

### `check_exposed_files`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
- Findings: high sensitive-path

Description, as the server wrote it:

```untrusted-server-text
Probe a site for accidentally exposed high-risk files (.env, .git/config, backups, etc.). Reports HTTP status only, never file contents.
```

### `check_security_headers`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
Grade a URL's HTTP security headers (CSP, HSTS, X-Frame-Options, Referrer-Policy, Permissions-Policy, COOP, COEP) A-F.
```

### `check_seo`

- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.

Description, as the server wrote it:

```untrusted-server-text
On-page SEO audit of a URL: title, meta description, H1, canonical, indexability, Open Graph, structured data, image alt coverage, sitemap. Returns an A-F grade.
```

### `scan_website`

- The description's first verb is "run": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Run a SimplyScan Security Engine security & speed scan (Pro with an entitled API key; otherwise free) of a deployed web app URL. Returns a 0-100 score and findings (exposed secrets, missing Supabase RLS, frontend leaks, speed issues). Best for apps built with Lovable, Bolt, v0, Cursor, Replit, etc.
```

## Only reads (1)

Looks things up and changes nothing. Claude Code: allow.

### `check_ssl`

- The description's first verb is "inspect": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Inspect a domain's SSL/TLS certificate: issuer, expiry, protocol, and flags for expiring/self-signed/mismatched certs.
```
