The server correctly utilizes environment variables for sensitive Jira credentials (JIRA_DOMAIN, JIRA_EMAIL, JIRA_API_TOKEN), preventing hardcoding. It uses axios for API calls, which is a standard and secure HTTP client. Error handling for API responses is implemented. A minor point is that `jira_get_attachment_image` currently hardcodes the `mimeType` to "image/png" in its response, which is a functional limitation (as noted in the source code TODO) rather than a direct security vulnerability, but it could lead to client-side misinterpretation if not handled carefully by the consuming AI. There are no obvious malicious patterns, use of `eval`, or obfuscation.
