A test can only see what the server shows from outside, not what it does with your data behind the scenes. Connect servers from makers you trust.
What it can do
27 tools, in the server's own words.
search_docsread-onlySearch the FynePDF API and MCP documentation: actions, parameters, pricing, files, jobs and errors.
list_actionsread-onlyEvery action FynePDF can run on a file (the REST API's job steps), with what it takes, what it makes and its price in API credits.
app_readyread-onlyFynePDF's in-chat cards say once which host bridge they run in, for diagnosis.
preview_fileread-onlyThe first pages of a PDF as images, for FynePDF's result viewer.
upload_fileBring a file into FynePDF.
import_file_from_urlFetch a PDF, Office file, image or EPUB from a public link into FynePDF and get its file_id.
get_fileread-onlyA file's details and a fresh download link (valid 1 hour).
list_library_filesread-onlyFiles saved in the person's FynePDF Library, newest first (pinned on top).
list_filesread-onlyFiles on FynePDF from the last 24 hours, newest first: what the person dropped in the upload box, other uploads and imports, and results.
save_to_libraryKeep a result in the person's FynePDF Library (fynepdf.com/library), so it isn't deleted after 24 hours.
merge_pdfsJoin PDFs into one, in the order given (file_ids, then files, then file_urls).
split_pdfSplit a PDF into parts by page ranges ("1-3", "4", "5-9") or into parts no bigger than max_part_mb.
edit_pagesChange 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 rang…
stamp_pdfNumber the pages, stamp a text watermark on every page, or both in one go.
compress_pdfMake a PDF smaller: at a level (low, medium, high) or under a target size in MB.
protect_pdflock: add a password needed to open it.
redact_pdfRemove 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.
convert_from_pdfTurn 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.
convert_to_pdfMake a PDF from Word, Excel or PowerPoint files, images (one page each, in order), an EPUB, or a public web page (url).
ocr_pdfAdd a text layer to scanned pages, so the text can be searched, copied and read by AI.
create_pdfTurn Markdown or HTML you write into a well-set PDF: a report, invoice, letter, resume or plain document.
sign_pdfStamp 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.
ask_pdfread-onlyAnswer a question from the document only, citing pages.
summarize_pdfread-onlyA plain summary and key points, each with the pages it comes from.
