## Changes things (2)

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

### `check_image`

- 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: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Check an image (PNG, JPEG, WebP, AVIF or single-page TIFF, up to 20 MiB) by public URL or base64 for C2PA Content Credentials, AI labels, saved generation settings and metadata. Evidence comes from records in the file, not a visual-only verdict. A URL check creates a public report by default; base64 uploads are private unless public_report is true. Docs: https://isgenai.com/developers/mcp
```

### `check_text`

- 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 pasted text or code (up to 16,000 characters) for statements of AI use and named AI tools such as ChatGPT, Claude, Gemini or Copilot, quoting the exact sentence. Does not judge authorship from writing style. Private by default; set public_report to create a public report URL. Docs: https://isgenai.com/developers/mcp
```

## Only reads (3)

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

### `check_url`

- The description's first verb is "fetch": a word for reading.
- Findings: info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Fetch a public web page or file and read AI labels, AI-use statements, Content Credentials and saved creation records found there. Logins, paywalls and CAPTCHAs are not bypassed. Public link checks create a public report by default (report_url); set public_report false to skip it. Docs: https://isgenai.com/developers/mcp
```

### `extract_saved_prompt`

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

Description, as the server wrote it:

```untrusted-server-text
Read the prompt, negative prompt, model and settings saved inside an image by AUTOMATIC1111, ComfyUI (including Flux workflows), InvokeAI or NovelAI. Only reads records stored in the file; it never reconstructs or guesses a prompt. Screenshots and re-uploads usually remove these records. Docs: https://isgenai.com/developers/mcp
```

### `read_content_credentials`

- The name "read_content_credentials" says "read": a word for reading.
- Findings: info credentials-mention, info credentials-mention, info credentials-mention

Description, as the server wrote it:

```untrusted-server-text
Read C2PA Content Credentials from an image, video, audio or PDF file (by public URL or base64, up to 20 MiB). Reports the manifest, recorded actions and digital source type, with cryptographic validation and signer trust as separate findings. Docs: https://isgenai.com/developers/mcp
```
