table above. ## Findings No check matched anything in these tool definitions. ## Deletes or cancels (1) Removes, cancels or revokes something. Claude Code: deny. ### `redact_pdf` - The description's first verb is "remove": a word for removing or ending something. - The server marks it destructive (destructiveHint: true). Description, as the server wrote it: ```untrusted-server-text Remove text for real, not just cover it: name the exact text to remove, or describe it ("all names, emails and account numbers") and FynePDF finds it. The result is checked: if any of the text can still be found, nothing is returned. The original file is kept. ``` ## Can't be undone (2) Sends, pays, publishes or merges: once done, it cannot be taken back. Claude Code: ask. ### `convert_from_pdf` - The name "convert_from_pdf" says "convert": a word for a change. - The input addresses people (input.to): what it sends cannot be taken back. - Tag outbound: The input takes a destination (input.to): what the tool writes goes there. Description, as the server wrote it: ```untrusted-server-text Turn a PDF into Word (.docx), Excel or CSV (tables found on the page), images (PNG/JPEG in a ZIP), Markdown, EPUB, PDF/A (archival), LaTeX, or a grayscale PDF. For tables read by AI (scans, bank statements), use extract_data. ``` ### `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 Join PDFs into one, in the order given (file_ids, then files, then file_urls). Each part gets a bookmark with its name. ``` ## Changes things (15) Creates or changes something that can be changed back. Claude Code: ask. ### `app_ready` - 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 FynePDF's in-chat cards say once which host bridge they run in, for diagnosis. Not for conversation. ``` ### `ask_pdf` - 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 Answer a question from the document only, citing pages. Every quote is checked against the page text (verified: false marks one that couldn't be found). ``` ### `compress_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 Make a PDF smaller: at a level (low, medium, high) or under a target size in MB. The result says whether the target was met. ``` ### `convert_to_pdf` - The name "convert_to_pdf" says "convert": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it. Description, as the server wrote it: ```untrusted-server-text Make a PDF from Word, Excel or PowerPoint files, images (one page each, in order), an EPUB, or a public web page (url). For content you write yourself, use create_pdf. ``` ### `create_pdf` - The name "create_pdf" says "create": a word for a change. Description, as the server wrote it: ```untrusted-server-text Turn Markdown or HTML you write into a well-set PDF: a report, invoice, letter, resume or plain document. Tables, headings, lists, images by URL and page breaks work; header, footer and page numbers are optional. For an invoice, resume or letter, prefer data (the fields, with template set to match): it is laid out properly, and an invoice is added up for you (leave out amounts, subtotal, tax or total to have them worked out; give them and they are checked). extract_data's invoice result can be passed as data as it is. Use it whenever the person wants a document they can download, print or send. ``` ### `edit_pages` - The name "edit_pages" says "edit": a word for a change. Description, as the server wrote it: ```untrusted-server-text Change a PDF's pages (counted from 1): delete pages, keep only some pages, put pages in a new order (pages left out are dropped), or rotate all pages or a range. ``` ### `import_file_from_url` - The name "import_file_from_url" says "import": a word for a change. - Tag untrusted-input: The server marks it openWorldHint: true: it reaches things outside the server's own data. - Tag outbound: The input takes a URL (input.url): a request to a URL can carry data to whoever runs it. Description, as the server wrote it: ```untrusted-server-text Fetch a PDF, Office file, image or EPUB from a public link into FynePDF and get its file_id. ``` ### `ocr_pdf` - The description's first verb is "add": a word for a change. Description, as the server wrote it: ```untrusted-server-text Add a text layer to scanned pages, so the text can be searched, copied and read by AI. ``` ### `protect_pdf` - The description's first verb is "lock": a word for a change. Description, as the server wrote it: ```untrusted-server-text lock: add a password needed to open it. unlock: remove a password you know. flatten: burn form fields and annotations into the page so they can't be changed. ``` ### `save_to_library` - The name "save_to_library" says "save": a word for a change. Description, as the server wrote it: ```untrusted-server-text Keep a result in the person's FynePDF Library (fynepdf.com/library), so it isn't deleted after 24 hours. ``` ### `sign_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 Stamp a signature image (PNG or JPEG) on a page: at a named spot (bottom-right by default) or at x and y in points from the top-left corner. ``` ### `smart_edit` - The name "smart_edit" says "edit": a word for a change. Description, as the server wrote it: ```untrusted-server-text Describe the change ("remove the blank pages, number the rest and make it PDF/A"): FynePDF plans the steps from its actions, checks the plan, and runs it. With run false it only returns the plan. ``` ### `split_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 Split a PDF into parts by page ranges ("1-3", "4", "5-9") or into parts no bigger than max_part_mb. Returns a ZIP of the parts. ``` ### `stamp_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 Number the pages, stamp a text watermark on every page, or both in one go. Page number format uses %d twice, e.g. "Page %d of %d". ``` ### `upload_file` - The name "upload_file" says "upload": a word for a change. Description, as the server wrote it: ```untrusted-server-text Bring a file into FynePDF. Shows a drop zone where the app supports it (Claude, ChatGPT, VS Code); it takes several files at once, e.g. for a merge, and reports their file_ids in order. With file_name and size_bytes it also returns a signed upload_url and a ready curl command, for a code sandbox or agent to PUT the bytes; the file_id works once the upload is done. ChatGPT users can just pass the attached file to any tool instead. ``` ## Only reads (9) Looks things up and changes nothing. Claude Code: allow. ### `extract_data` - The description's first verb is "read": a word for reading. - Tag private-data: The description's first sentence says "read" and "table": it reads databases. The input names a file (input.file_id), and the tool reads: it reads files. Description, as the server wrote it: ```untrusted-server-text Read structured data with AI and check it in code: invoice (fields, lines and totals, added up), statement (bank transactions, balances compared), tables (every table, cell by cell), or schema (your own JSON Schema). Output json returns the data here; excel or csv also makes a spreadsheet file (tables and statement). ``` ### `get_file` - The name "get_file" says "get": a word for reading. - Tag private-data: The name "get_file" says "get" and "file": it reads files. The description's first sentence says "file": it reads files. The input names a file (input.file_id), and the tool reads: it reads files.
