Setup Guide

Connect in Under 60 Seconds

Three steps from a fresh Claude install 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. An active paid subscription is required to use the server inside Claude. See paid plans →
  1. 1

    Add the MCP Server

    Open your terminal and run:

    claude mcp add --scope user --transport http pdfAssistant https://chat.pdfassistant.ai/mcp
  2. 2

    Authenticate

    Launch Claude Desktop, type /mcp in any conversation, and complete the secure OAuth login when the popup appears.

  3. 3

    Start Processing

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

    • “Compress this to under 5MB”
    • “Convert to PDF/A for archival”
    • “Redact all Social Security Numbers using regex”
    • “Merge these three files and add a watermark”

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