RSH-MCP Server

An MCP (Model Context Protocol) server that provides remote shell and file operations using the legacy RSH/RCP protocols for connecting to vintage computer systems.

Features

• exec: Execute commands remotely via RSH protocol
• read: Read files from remote hosts via RCP protocol
• write: Write files to remote hosts via RCP protocol

Installation

Using go install

go install github.com/tenox7/rsh-mcp@latest

This will install the rsh-mcp binary to your $GOPATH/bin directory (typically ~/go/bin).

Claude Code Configuration

Use the Claude Code CLI to add the MCP server:

claude mcp add rsh-mcp /path/to/rsh-mcp

File editing consideration

rsh-mcp provides read/write facility using rcp copy in/out. However this is not very effective for editing files. It's generally advised to make your agent write/edit/modify files locally then copy them over. Even better mount the workspace folder locally and remotely via NFS/SMB so the files can be edited in place.

Privileged port

Some RCP/RSH servers require connections source port to be privileged range (<1024). This rsh/rcp client does that but on some OS'es it may require elevated privileges.

Optional: Configuration with Default Settings

You can override defaults if you want to always use the same username/target:

{
  "mcpServers": {
    "rsh-mcp": {
      "command": "rsh-mcp",
      "args": [],
      "env": {
        "RSH_DEFAULT_HOST": "192.168.1.100",
        "RSH_DEFAULT_USER": "your_username",
        "RSH_DEFAULT_PORT": "514"
      }
    }
  }
}
