What andresthor cmd line mcp gives an AI Agent

The source catalog does not include a structured feature list. Review the repository documentation before use.

SECURITY

An MCP listing is not a security review

An MCP server may receive model context, credentials, local files, or permission to call external systems. Review its code, requested environment variables, network behavior, package provenance, and maintenance status before connecting it to an agent.

Command-Line MCP Server

PyPI version Python Versions License: MIT

An MCP server that lets AI assistants run terminal commands safely. Commands are categorized (read/write/system), directories are whitelisted, and dangerous patterns are blocked automatically.


Quick Start

pip install cmd-line-mcp

# Or from source
git clone https://github.com/andresthor/cmd-line-mcp.git
cd cmd-line-mcp
pip install -e .

Run the server:

cmd-line-mcp                        # default config
cmd-line-mcp --config config.json   # custom config

Claude Desktop Setup

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "cmd-line": {
      "command": "/path/to/venv/bin/cmd-line-mcp",
      "args": ["--config", "/path/to/config.json"],
      "env": {
        "CMD_LINE_MCP_SECURITY_REQUIRE_SESSION_ID": "false",
        "CMD_LINE_MCP_SECURITY_AUTO_APPROVE_DIRECTORIES_IN_DESKTOP_MODE": "true"
      }
    }
  }
}

Restart Claude Desktop after saving.

Tip

Set require_session_id: false to prevent approval loops in Claude Desktop.


How It Works

Commands go through a validation pipeline before execution:

  1. Pattern matching — blocks dangerous constructs (system(), shell escapes, etc.)
  2. Command classification — each command must be in the read, write, system, or blocked list
  3. Directory check — target directory must be whitelisted or session-approved
  4. Approval check — write/system commands require session approval

Pipes, semicolons, and & are supported — each segment is validated independently.

What's Allowed

Category Commands Approval
Read ls, cat, grep, find, head, tail, sort, wc, … Auto
Write cp, mv, rm, mkdir, touch, chmod, awk, sed, … Required
System ps, ping, curl, ssh, xargs, … Required
Blocked sudo, bash, sh, python, eval, … Always denied

What's Blocked

Shells, scripting interpreters, and known command-execution vectors are blocked — including indirect execution through awk system(), sed /e, find -exec, tar --checkpoint-action, env, and xargs. See docs/SECURITY.md for the full list.


Configuration

The server works out of the box with sensible defaults. Customize via JSON config, environment variables, or .env files:

# Whitelist directories
export CMD_LINE_MCP_SECURITY_WHITELISTED_DIRECTORIES="/projects,/var/data"

# Add commands (merges with defaults)
export CMD_LINE_MCP_COMMANDS_READ="jq,rg"

See docs/CONFIGURATION.md for full configuration reference, MCP tool documentation, and directory security details.
