mcp-server

The server demonstrates good security practices such as sanitizing URL parameters to prevent command injection (`sanitizeUrlParam`), validating URLs and payload sizes in network requests (`apiClient.validateUrl`), and sourcing credentials from environment variables rather than hardcoding. It uses `execSync` and `childProcess.spawn` for system commands (`pgrep`, `taskkill`, `open`, `start`, `xdg-open`) and `browserstack-local` binary management, where arguments are generally fixed or carefully constructed, reducing direct shell injection risk. File system access for listing test files (`listTestFiles`) is an expected feature for a development tool but could potentially expose local file paths if the base directory input is not adequately constrained by the invoking client. The `rejectUnauthorized: false` for custom CA certificates in `apiClient` is a configuration-dependent risk. Overall, while interacting with the local system and external APIs, the implementation shows a conscious effort towards security.
