## Exfil surface

No private-data -> untrusted-input -> outbound path in this server alone: no tool is tagged private-data or untrusted-input or outbound.

| Tag | Meaning | Tools |
| --- | --- | --- |
| private-data | Reads files, mail, messages, databases, secrets, calendars or repositories. | none |
| untrusted-input | Brings in text someone else can write: web pages, inbound email, messages, issues and comments. | none |
| outbound | Can carry data to people or systems: it sends, posts or publishes, or takes a recipient, channel or URL. | none |

## Findings

No check matched anything in these tool definitions.


## Can't be undone (1)

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

### `merge_pdfs`

- The name "merge_pdfs" says "merge": a word for a change that another call does not undo.

Description, as the server wrote it:

```untrusted-server-text
Merge two or more PDF files into a single PDF, in the order given. Input: a list of base64-encoded PDF file contents (each max 25 MB / 500 pages). Returns a download_url for the merged PDF (link valid 24 hours), its size and page count. Costs 1 credit; 5 free calls per month.
```

## Changes things (3)

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

### `images_to_pdf`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Combine one or more images (PNG/JPEG/WebP) into a single PDF, one image per page, pages sized to each image. Input: a list of base64-encoded image contents (each max 15 MB / 40 MP). Returns a download_url for the PDF (link valid 24 hours), its size and page count. Costs 1 credit; 5 free calls per month.
```

### `pdf_form_fill`

- The name "pdf_form_fill" says "fill": a word for a change.

Description, as the server wrote it:

```untrusted-server-text
Fill the fields of a fillable PDF form and return the completed form. Input: the PDF's contents as a base64-encoded string, plus a fields object mapping field names to values. Unknown field names are rejected with a list of the form's real fields. Checkboxes accept true/false; radio groups take the chosen option's name; dropdowns take one of their defined choices. Set flatten=true to bake values in so they can no longer be edited. Returns a download_url for the filled PDF (link valid 24 hours). Costs 1 credit; 5 free calls per month.
```

### `pdf_tables_to_excel`

- Nothing in its name or description says what it does, so it is counted as a write.

Description, as the server wrote it:

```untrusted-server-text
Extract all tables detected in a PDF into an Excel (.xlsx) workbook, one worksheet per table. Input: the PDF file's contents as a base64-encoded string (max 25 MB, 500 pages; tables need visible ruling lines or clearly aligned columns). Returns a download_url for the .xlsx file (link valid 24 hours) plus the table count. Costs 1 credit; 5 free calls per month.
```
