Common questions
Is Epublys safe?
It passed 4 of 4 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed 24 days ago, and the latest version (1.0.1) reached the registry 5 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT on the web (full MCP on Business and above; Pro read-only).
What can I use instead?
In the same category: Puter MCP, XcodeBuildMCP, Anki MCP Server, Sosumi, Zapier

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: none needed for the free tier. An optional Bearer API key (free at https://epublys.com/account) carries your account's allowance and Pro.
- Server card: https://epublys.com/.well-known/mcp/server-card.json
- Full agent docs: https://epublys.com/llms-full.txt
- Registry:
com.epublys/epublyson the official MCP registry
Quickstart
Without a key (free tier)
Claude Code:
claude mcp add --transport http epublys https://epublys.com/mcpAny other MCP client (claude_desktop_config.json, cline_mcp_settings.json, etc.):
{"mcpServers": { "epublys": { "url": "https://epublys.com/mcp" } } }
The free tier is identified by IP address and shares the website's free daily allowance. It is permanent, not a trial.
With a key (your account's allowance, Pro)
- Sign in at https://epublys.com/account and create an API key (
epl_…— shown once). - Send it as a Bearer header:
{"mcpServers": { "epublys": { "url": "https://epublys.com/mcp", "headers": { "Authorization": "Bearer epl_YOUR_KEY_HERE" } } } }
Claude Code: claude mcp add --transport http epublys https://epublys.com/mcp --header "Authorization: Bearer epl_YOUR_KEY_HERE"
A wrong, malformed or revoked key is a 401, not a silent fall back to the free tier. The key goes in the Authorization header only; a key in the URL is rejected.
