Epublys MCP Server

Remote MCP server for EPUB and PDF ebook manipulation — merge, split, compress, convert, edit metadata, validate, and generate AI covers. Backed by epublys.com, running on Cloudflare Workers.

This is a hosted server (Streamable HTTP). There is nothing to install — this repository holds the public manifests, configuration examples, and documentation.

• Endpoint: https://epublys.com/mcp (Streamable HTTP)

• Auth: Bearer API key — free at https://epublys.com/account

• Server card: https://epublys.com/.well-known/mcp/server-card.json

• Full agent docs: https://epublys.com/llms-full.txt

• Registry: com.epublys/epublys on the official MCP registry

About this repository

The Epublys service itself is closed-source. This repository contains only the public MCP manifests (server.json, smithery.yaml) and documentation, and is the canonical public home for the com.epublys/epublys registry entry.
