Tools as reported by the server

• compare_pdfs
  MANDATORY for all document comparison requests. Compare two PDFs side-by-side. When the user asks to compare, diff, or find differences between two PDFs, you MUST call this tool — NEVER attempt to compare documents using text analysis. Displays an interactive side-by-side visual diff widget with col
• get_latest_comparison
  Re-run the most recent PDF comparison for a session. For widget recovery only. The comparison widget calls this when the host did not hand it the comparison payload. Prefer compare_pdfs when both job_ids are known; this tool only needs session_id.
• compress_pdf
  Compress a PDF to reduce its file size and return a new versioned file. MANDATORY: Before calling this tool, call 'check_upload_status' with the session_id to confirm the file exists and retrieve the latest job_id. Skipping this check and calling compress_pdf directly is FORBIDDEN. Each call creates
• delete_pdf_page
  Delete one or more pages from a PDF and return a new versioned file. MANDATORY: Before calling this tool, call 'check_upload_status' with the session_id to confirm the file exists and retrieve the latest job_id. Skipping this check and calling delete_pdf_page directly is FORBIDDEN. SAFE AND REVERSIB
• set_password
  Add password protection to an unprotected PDF file. Creates a NEW job_id (with parent_job_id linking to the source). After the operation completes, call 'view_pdf' with the new job_id to display the result. Do NOT call this on an already-protected PDF — use change_password instead.
• change_password
  Change the password of an already-protected PDF file. Creates a NEW job_id (with parent_job_id linking to the source). After the operation completes, call 'view_pdf' with the new job_id to display the result. Do NOT call this on an unprotected PDF — use set_password instead.
• list_redactable_line_text
  Return per-page, per-line text for identifying redaction targets. Read-only: does not modify job state. ALWAYS call this before redact_by_text_range. The returned 'text' field for each line is the source of truth — you MUST use it to count exact character positions. Character positions within each l
• redact_by_text_range
  Redact PDF text by specifying the exact text to remove on each line. MANDATORY WORKFLOW — follow every step in order before calling this tool: Step 1 — Retrieve line text: Call list_redactable_line_text and note the exact 'text' string and 'line_index' for every line you intend to redact. Step 2 — I
• upload_pdf
  Upload a PDF from a ChatGPT file attachment. MANDATORY WORKFLOW — follow EVERY step in order: 1. ALWAYS call check_upload_status FIRST — even if you think the file is new. 2. If a job with the same filename already exists, reuse its job_id — do NOT call upload_pdf. 3. Only call upload_pdf if the fil
• batch_upload_pdf
  Upload multiple PDF files from ChatGPT file attachments. Use this when the user provides multiple file attachments in ChatGPT. Downloads each PDF from its signed URL and stores it. Returns session_id and a list of job_ids. Like upload_pdf, this ONLY works on hosts that resolve chat attachments for y
• create_upload_page
  Display an interactive PDF upload widget directly in the chat. Use this when the user wants to upload a local PDF file from their device. This is the standard upload method for MCP clients (e.g. Claude) where file attachments with download URLs are not available. Do NOT call upload_pdf when using th
• check_upload_status
  Check existing uploads and determine which files still need uploading. Call this BEFORE upload_pdf or create_upload_page to avoid duplicate uploads. Also call it after the user uploads via the widget to discover the new file and its job_id. Returns 'session_id' (always — store it!), plus: - 'already
• view_pdf
  Display an already-uploaded PDF in an interactive viewer widget. Call this after delete_pdf_page, set_password, change_password, redact_pii, and redact_by_text_range to show the updated PDF. Also call when the user explicitly asks to (re-)display a specific PDF. AFTER AN UPLOAD — this is the step th
• get_pdf_status
  Return current status of a PDF viewer job. Used internally by the viewer widget.
• get_pdf_info
  Use this when you need to read the text content of each page to decide which pages to delete. Returns page count and a text preview of every page. Use for text-based identification: table of contents, blank pages, cover page, etc. For visual content (logos, images, photos), use get_pdf_page_images i
• get_pdf_page_images
  Use this when you need to visually inspect PDF pages to identify content that cannot be detected from text alone — for example, pages containing a logo, a photograph, a watermark, a QR code, or any visual element. Returns rendered JPEG screenshots as images you can see. Returns at most 10 pages per
