Setup Guide

Connect in Under 60 Seconds

Four steps from Developer Mode to a fully connected PDF toolbox.

Prerequisite: The MCP server is available on pdfAssistant paid plans only — it is not included on the free tier. You'll need an active paid subscription to authenticate ChatGPT and use the server. See paid plans →
  1. 1

    Enable Developer Mode

    In ChatGPT, go to Settings → Apps and enable Developer Mode.

  2. 2

    Add pdfAssistant as a Remote App

    Configure a new remote app pointing to:

    https://chat.pdfassistant.ai/mcp
  3. 3

    Authenticate

    Complete the secure OAuth login when prompted. Your pdfAssistant credentials authorize ChatGPT to use your tools and credits.

  4. 4

    Start Processing

    Drop a PDF into your ChatGPT conversation and describe what you need:

    • “Convert this spreadsheet to a formatted PDF”
    • “Merge these five documents into one”
    • “Add a Confidential watermark to every page”
    • “Extract all form data and export it”

    ChatGPT calls pdfAssistant's tools, processes the file in the cloud, and delivers the result in your chat.

Use Case Examples

Real ChatGPT + pdfAssistant scenarios.

Single prompts that orchestrate multiple tools end to end.

Report Generation

“Convert this HTML page to PDF, compress it, and add our company watermark.” ChatGPT chains three tools and delivers a branded report.

Secure Document Delivery

“Encrypt this PDF with a password, add print restrictions, and remove the existing editing permissions.” ChatGPT applies layered security in one request.

Data Extraction

“Extract all the text from this scanned document using OCR, then pull the table data into a structured format.” ChatGPT runs OCR and extraction back-to-back.

Format Conversion

“Turn this Word doc into a PDF/X file ready for print production.” ChatGPT handles the conversion with print-standard compliance.
