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/epublys on the official MCP registry

Quickstart

Without a key (free tier)

Claude Code:

claude mcp add --transport http epublys https://epublys.com/mcp

Any 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)

1. Sign in at https://epublys.com/account and create an API key (epl_… — shown once).

2. 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.
