PaperSprocket MCP server

A Model Context Protocol (MCP) server that gives MCP clients direct access to the PaperSprocket API. It exposes exactly two tools:

This is a minimal native MCP server built directly on @modelcontextprotocol/sdk. No top-up tools, no API-key-management tools — just render and balance-check.

What is PaperSprocket?

PaperSprocket is a hosted API that turns HTML into PDFs. You send it HTML, it returns a well-formed PDF. There is no business-field schema to learn: you control the layout with your own HTML and CSS, PaperSprocket handles the PDF processing. See the official documentation.

Requirements

only (environment or .env) — it is never** a caller-supplied tool argument, and is never embedded in source, examples, or this document.

  • Node.js >= 20
  • A PaperSprocket API key. The server reads it from **server-side config

Install

Run via npx (primary)

npx -y papersprocket-mcp

The package papersprocket-mcp is published to npm and registered in the official MCP Registry under identity io.github.inde-x/papersprocket (active, version 1.0.0). Point your MCP client at npx -y papersprocket-mcp and provide PAPERSPROCKETAPIKEY in the client's environment (the server reads it server-side only).

From source (optional / development)

git clone https://github.com/inde-x/papersprocket-mcp.git
cd papersprocket-mcp
npm ci
cp .env.example .env   # then set PAPERSPROCKET_API_KEY (see Configuration)

Configuration

The server loads /.env at startup (it does not override already-set environment variables). .env is gitignored.

Example .env (replace the placeholder — never commit a real key):

PAPERSPROCKET_API_KEY=psk_your_api_key_here
# PAPERSPROCKET_BASE_URL=https://papersprocket.com/api
# PAPERSPROCKET_MCP_OUTPUT_DIR=./output

Run (stdio)

node server.js                 # MCP over stdio
node server.js --list-tools    # print tool schemas, then exit

Connect an MCP client

Point your MCP client at a stdio server:

# primary — published npm distribution:
Command:   npx
Arguments: -y papersprocket-mcp

# or a local source checkout:
Command:   node
Arguments: /path/to/papersprocket-mcp/server.js

PAPERSPROCKETAPIKEY is provided via the server .env or environment — never in the client configuration.

MCP Inspector

npx @modelcontextprotocol/inspector node /path/to/papersprocket-mcp/server.js

List tools → confirm exactly two: renderhtmltopdf and checkbalance.
