About
MCP server for executing sudo commands with encrypted password storage, allowing privileged operations without re-entering credentials.
README
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.
