How to run a local PDF extraction API for Python, n8n or Open WebUI with Paper Pilot

Start Paper Pilot's local REST API and send it documents from your own scripts or automations.

Short answer: Install Paper Pilot from Releases or build the gateway from source; then start the server with paperpilot serve --port 7823; call it from Python, Node or an n8n HTTP node at localhost:7823. All steps.

Who it is forA developer building a document pipeline who needs PDF text and tables extracted on their own server.

The problemCloud extraction APIs cost money per page and send private documents to third parties.

The outcomeA REST endpoint on localhost that returns structured text and Markdown tables from PDFs.

What you need first

  • The paperpilot or paperpilot-mcp binary from GitHub Releases, or Rust 1.75+ to build from source
  • An MCP client such as Claude Code, Codex, Cursor or Claude Desktop for agent use
  • Node.js and pnpm only for the desktop app

Steps

  1. Install Paper Pilot from Releases or build the gateway from source
  2. Start the server with paperpilot serve --port 7823
  3. Call it from Python, Node or an n8n HTTP node at localhost:7823
  4. For Open WebUI, follow the README's integration guide to use it as a Tika-compatible extraction server

Prompt for your agent

Start KrushnaVardhanReddy/PaperPilot's local REST API on port 7823 and write a <Python or n8n> step that sends <pdf> to it and saves the extracted text and Markdown tables.

Caveat. This card is written from the KrushnaVardhanReddy/PaperPilot README, not from a test run by Deduped. Before you start, make sure you have the paperpilot or paperpilot-mcp binary from GitHub Releases, or Rust 1.75+ to build from source. Check the repo for newer instructions before you rely on these steps.
