jira-mcp-server

The server uses environment variables for sensitive credentials (JIRA_EMAIL, JIRA_API_TOKEN), which is a good security practice. There's no use of 'eval' or obvious code obfuscation. Dependencies are standard and widely used. The construction of JQL queries directly embeds parameters (`projectKey`, `status`, `JIRA_ASSIGNEE_ACCOUNT_ID`), which, in theory, could be vulnerable to JQL injection if the client (LLM) were to provide malicious input. However, in the context of an LLM tool, this risk is generally mitigated by careful prompt engineering and the LLM's adherence to tool parameter schemas. Overall, for its intended use as a private integration, it appears reasonably secure.
