MCP stdio ShellGuard Overview

MCP stdio ShellGuard provides guarded wrappers for Node.js `child_process.exec` and `child_process.spawn`, with default-deny allowlists, sandbox limits, and replay detection. Its reference MCP server exposes execution controls, trust assessment, sandbox status, and source-audit tools for TypeScript and JavaScript paths. The companion CLI scans server code for shell-injection anti-patterns and can emit Markdown, JSON, or SARIF 2.1.0 reports. Reach for it when an MCP stdio server needs controlled subprocess execution and security checks in development or CI.

Primary Use Cases for MCP stdio ShellGuard:
  • Wrap MCP subprocess calls with default-deny execution rules
  • Scan TypeScript or JavaScript MCP sources for shell-injection patterns
  • Gate CI builds on audit findings above a chosen severity
  • Check repeated invocations before allowing execution
