epub-novel-mcp-server

An MCP server for creating and editing EPUB novels, built on the official Go SDK (github.com/modelcontextprotocol/go-sdk). It exposes tools for reading and writing an EPUB's metadata, chapters, navigation, cover, and resources.

The server runs over Streamable HTTP and listens on 0.0.0.0:8383. MCP clients connect to the running server at http://127.0.0.1:8383; the process is not spawned per-connection over stdio — it runs independently, either in the foreground or as a managed background service.

Prerequisites

• Go 1.26 or newer.

Build

# Linux / macOS
go build -o epub-novel-mcp-server .

# Windows (PowerShell)
go build -o epub-novel-mcp-server.exe .

This produces a single self-contained binary.

Run from the command line

Run the binary with no arguments to start the server in the foreground:

./epub-novel-mcp-server
# → epub-novel-mcp-server listening on http://0.0.0.0:8383

Press Ctrl-C to stop it. This is the simplest way to run the server for local use or development.

Install as a background service

The binary can install itself as a native service on Windows, Linux, and macOS (via github.com/kardianos/service). The same subcommands work on every platform:

Installing/managing a system service requires elevated privileges on every platform.

Windows (Windows Service)

Run from an Administrator PowerShell / Command Prompt:

.\epub-novel-mcp-server.exe install
.\epub-novel-mcp-server.exe start

The service appears in Services (services.msc) as EPUB Novel MCP Server and starts automatically on boot. Manage it there or with sc.exe as well.

.\epub-novel-mcp-server.exe stop
.\epub-novel-mcp-server.exe uninstall

Linux (systemd)

Run with sudo (installs a systemd unit):

sudo ./epub-novel-mcp-server install
sudo ./epub-novel-mcp-server start

Then manage it through systemd if you prefer:

sudo systemctl status epub-novel-mcp-server
sudo systemctl enable epub-novel-mcp-server   # start on boot
journalctl -u epub-novel-mcp-server -f        # follow logs

Uninstall:

sudo ./epub-novel-mcp-server stop
sudo ./epub-novel-mcp-server uninstall

macOS (launchd)

Run with sudo (installs a launchd daemon):

sudo ./epub-novel-mcp-server install
sudo ./epub-novel-mcp-server start

Uninstall:

sudo ./epub-novel-mcp-server stop
sudo ./epub-novel-mcp-server uninstall

Connect an MCP client

Point your MCP client at the running server's HTTP endpoint. For a Claude-style .mcp.json:

{
    "mcpServers": {
        "epub-novel-mcp-server": {
            "type": "http",
            "url": "http://127.0.0.1:8383"
        }
    }
}

The server must already be running (foreground or as a service) before the client connects — an http transport does not launch the process itself. If starting the server reports that the port is already in use, it is most likely already running; just connect to the existing endpoint.

Configuration & security notes

• Address: the server binds 0.0.0.0:8383, so it is reachable both on loopback (127.0.0.1) and from other machines on the LAN at the host's IP.

• DNS-rebinding protection: the SDK rejects (403) requests that arrive over a localhost address but carry a non-localhost Host header. Normal 127.0.0.1:8383 and LAN-IP access are unaffected.

• Intended for local / trusted-network, single-user use.
