@mukundakatta/shellquote-mcp v0.1.0 — Shell Argument Escaping
Install: npm install @mukundakatta/shellquote-mcp Binary: shellquote-mcp (entry: src/index.js) Transport: stdio Tools (4): quote_bash (single arg → escaped), quote_bash_argv (arg array → command string), quote_cmd (Windows cmd.exe escaping), quote_powershell (PS single-quote escaping)
Key behaviors
quote_bash: wraps in single quotes; safe barewords returned unquoted; embedded single quotes escaped as'\''quote_bash_argv: joins array into a space-separated, fully-escaped command stringquote_cmd: double-quote wrapping with doubled internal quotes; warns about^ ! %corner casesquote_powershell: single-quote wrapping with doubled internal single quotes; no variable expansion
Gotchas
- All tools return JSON objects (
{"quoted":"..."}or{"command":"..."}) not plain strings Infinity,NaNetc. are NOT special — treated as regular strings- First two calls ~150ms (JIT), subsequent calls 3–11ms
When to use
Agents building CLI commands from user input or LLM output MUST escape arguments to prevent shell injection. This server handles bash, cmd.exe, and PowerShell in one place.
