mcp-sudo

<!-- mcp-name: io.github.KamaruSama/mcp-sudo -->

MCP server for running sudo commands with encrypted password storage.

Exposes 4 tools to persist a sudo password (encrypted with a machine-bound key) and invoke privileged commands without re-entering credentials. Designed for single-user Linux workstations.

Tools

Tool Purpose
store_password Store sudo password (encrypted, one-time)
sudo_exec Run shell command with sudo
has_password Check if password is stored
clear_password Remove stored password

Security model

  • Password is encrypted with Fernet (AES-128-CBC + HMAC-SHA256).
  • Encryption key is derived from machine-id + USER — never stored on disk.
  • Decryption only succeeds on the same machine with the same user.
  • Encrypted blob lives at ~/.config/claude-sudo-mcp/credential.enc (chmod 600).

This is not a secrets manager. Treat this as "remember my sudo password for this session on this box." If your machine-id is copied to another box or another user reads the MCP process, the password can be recovered.

Install

cd /path/to/mcp-sudo
uv venv --python 3.12 .venv
uv pip install --python .venv/bin/python mcp cryptography

claude mcp add sudo -s user -- \
  /path/to/mcp-sudo/.venv/bin/python /path/to/mcp-sudo/server.py

On first use, call store_password once to cache credentials.
