Claude

Add FynePDF to Claude (claude.ai and the Claude apps) as a custom connector and work on PDFs in your chats.

Add the connector

  1. In Claude, open Settings, Connectors (on some versions, Customize, Connectors).
  2. Choose Add custom connector.
  3. Name it FynePDF and enter the URL:
https://api.fynepdf.com/mcp
  1. Choose Add, then Connect. fynepdf.com opens: sign in and choose Allow.

If Claude asks how the connector signs in, choose Sign in when needed, not "No sign-in": FynePDF's tool list opens without an account, so Claude can guess wrong. Leave the OAuth fields empty; Claude registers itself. Connectors you add on claude.ai also work in the desktop and mobile apps. On the Free plan you can add one custom connector; on Team and Enterprise, an owner adds it for the organization.

Use it

Turn FynePDF on for a chat from the tools menu, then ask in plain words:

  • "Compress this PDF to under 5 MB."
  • "Redact every name and phone number in this contract."
  • "Turn these three invoices into one Excel sheet."
  • "Make an invoice for Acme: 3 hours of consulting at $120, 10% tax."

Attach the file to the chat, or let Claude show FynePDF's drop zone. The result comes back as a card with a preview, Download and Save to Library.

When something's off

  • "Connect" does nothing: allow pop-ups for claude.ai; the sign-in opens in a new window.
  • A tool asks you to sign in again: you disconnected it in Developers, Assistants, or the sign-in expired. Choose Connect again.
  • "Plan limit reached": the job went over your fynepdf.com plan's daily tasks or AI allowance. The message names the limit.
