Unmeasured means there is not enough evidence to decide. How these checks work

Inspect individual checks 22 recorded

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 132 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name mcp-pdf.

  • Pass
    Lists tools

    tools/list returned 15 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 132 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 132 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    41 of 42 parameters have a description (98%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Pass
    Source repo linked

    A repository URL is on file.

  • Pass
    Repo owner matches

    The GitHub repository owner matches the namespace login.

  • Pass
    Recently updated

Capabilities

Tools 15

license_activate

Turn Pro on for this connection with key, an MCPL1.<payload>.<signature> issued at checkout for this server or the bundle. Data under your token stays; a wrong or expired key changes nothing. license_status confirms it.

Discovered
license_status

Report this endpoint's licence state for your token as JSON: the product, the tier free or pro, why it is not Pro, and the checkout URL. Call it to explain a free-tier refusal. No arguments, nothing changes.

Discovered
pdf_count

Page count per file plus the total, for any number of PDFs, with how many were readable. A file that cannot be read is reported on its own row and the others still count. Read-only. Free and unlimited.

Discovered
pdf_delete_upload

Delete one PDF stored for your token, uploaded or generated.

Discovered
pdf_files

List the PDFs stored for your token: what you uploaded, and what this server has written, with their sizes.

Discovered
pdf_info

Call this tool to inspect a PDF: page count, page sizes in points/mm, paper name, metadata (title, author, producer, dates) and whether it is encrypted. Read-only, never modifies the file. Free tier: unlimited.

Discovered
pdf_merge

Call this tool to join several PDFs into one, in the order given. Page sizes are kept as-is, so a merged file may have mixed sizes, and the answer says so. Inputs are never modified. Free tier: up to 5 files per merge.

Discovered
pdf_pages

Call this tool to pull selected pages into one new PDF, in the order written: "2,4-6" gives four pages. Asking for a page twice copies it twice. The input is never modified. Free tier: files up to 30 pages.

Discovered
pdf_reorder

Call this tool to write a new PDF with pages in the order you give. The order must name every page exactly once, so nothing drops by accident; use pdf_pages for a subset. Pro.

Discovered
pdf_rotate

Call this tool to turn pages by a multiple of 90 degrees, clockwise for positive. Rotation is added to whatever the page already had, for a sideways scan. Writes a new file. Free tier: files up to 30 pages.

Discovered
pdf_split

Call this tool to write one new PDF per range. Ranges are 1-based and may be open-ended: "1-3,5,7-" gives pages 1-3, page 5, and 7 to the end. The input is never modified. Free tier: files up to 30 pages.

Discovered
pdf_stamp

Call this tool to draw a word such as PAID or DRAFT across the pages, in a colour and position you choose. Writes a new file; input untouched. Free tier: the PAID and DRAFT presets in their preset colours.

Discovered
pdf_text

Call this tool for best-effort text extraction from standard-font PDFs. Returns nothing for a scan (no OCR), or glyph indices for a custom-encoded font, and says which case applies. Read-only. Free tier: unlimited.

Discovered
pdf_upload

Send a PDF to this hosted endpoint. There is no filesystem here, so instead of a path you upload the file once with pdf_upload and then pass its name as `path` (or inside `paths`) to pdf_info, pdf_count, pdf_merge, pdf_split, pdf_pages, pdf_rotate, pdf_stamp, pdf_reorder and pdf_text. Give exactly one of pdf_base64 or url. url: fetch a public file instead of pasting base64 (recommended above about 10 KB): pasting a large base64 payload is slow to write out and can stall the turn before the call is ever sent, while a url costs one line and the fetch happens here. Uploads are kept for your token between calls; pdf_files lists them and pdf_delete_upload removes one. A file this server writes is named the same way and comes back as a download link valid for one hour. The request body cap is 256 KB, which is about 190 KB of PDF once base64-encoded; a url is fetched with a 10 second timeout, at most 3 redirects, public http(s) hosts only, and is capped at 2 MB.

Discovered
pdf_watermark_business

Call this tool to put your business name and VAT id in the footer of every page, from the shared profile mcp-invoice and mcp-docx write. Use it before sending a document out. Pro.
