MCP PDF Tools in Claude.ai and Claude Desktop connectors

Merge, split, stamp and read PDFs, pure JavaScript, no upload. It merges and splits PDFs, extracts and reorders pages, rotates a sideways scan, stamps PAID or DRAFT or any text, watermarks the business name and VAT id from the shared profile, and reads text back best effort with no OCR.

A merged or stamped PDF comes back as a one-hour download link rather than a path, and pdf_watermark_business needs the shared business profile to already exist behind that same token, since there is no local profile.json to read it from.

What you get

You say	Tool
Stamp PAID on this invoice and save a copy.	`pdf_stamp`
Join these three PDFs into one file.	`pdf_merge`
Split the scan: pages 1-3 are the invoice, 4 onwards is the receipt.	`pdf_split`

The worked run stamped PAID on a 1-page invoice and wrote a new 0.9 MB file; the original file was byte-for-byte unchanged, which every writing tool here guarantees on purpose.

Connect it, no install

https://mcp.zovo.one/mcp/connect mints an anonymous token and prints a URL per server, including this one, shaped like https://mcp.zovo.one/mcp/pdf/t/<token>. That URL works with no headers: the token is in the path, not in an Authorization field this form does not have.

Open https://mcp.zovo.one/mcp/connect and copy the URL printed for MCP PDF Tools.
There is no config file here: the Add custom connector form asks for a name and a Remote MCP server URL, with an Advanced settings section for an optional OAuth Client ID and Client Secret.
Paste the URL as the Remote MCP server URL. Leave the optional OAuth Client ID and Client Secret blank; this endpoint does not use them.
Click Connect, then turn the connector on for a conversation from the + button, Connectors.

Idle anonymous tokens are swept after 30 days. Since this route has no filesystem, a file MCP PDF Tools generates comes back as a download link that expires after one hour. A Pro key can replace the token in the same URL and removes the free-tier limits.

Claude.ai and Claude Desktop connectors notes worth knowing first

On an individual Pro or Max plan you add the connector yourself from Customize, Connectors. On Team and Enterprise it is the other way round: only an Owner or Primary Owner can add a custom connector, at Organization settings, Connectors, and members then connect to what the Owner added rather than pasting their own URL.

Free: info, count and text unlimited; merge up to 5 files; edits on files up to 30 pages; the PAID and DRAFT stamp presets. Pro is $19 once, verified offline, and binds to the token after checkout.

Questions

Does this need OAuth?

No. Add custom connector offers an Advanced settings section with an OAuth Client ID and Client Secret, but the connect-by-URL route does not use it. Leave both blank: the token in the URL path is what authenticates.

I am on a Team or Enterprise plan and cannot add a connector.

That is documented, not a bug: on Team and Enterprise, only an Owner or Primary Owner can add a custom connector, at Organization settings, Connectors, Add, Custom, Web. After that, members connect to the URL the Owner added from Customize, Connectors.

Can I use my Pro key instead of the free anonymous token?

Yes. The token segment of the URL from /mcp/connect can be replaced with a Pro key, which removes the free-tier limits on MCP PDF Tools for that connector.

Why did a generated file come back as a link instead of opening?

The connector runs server-side with no filesystem of its own, so any file MCP PDF Tools produces is handed back as a download link that expires after one hour, rather than a path on disk.
