The server's design inherently enhances security by offloading PII redaction and policy validation to local scripts/skills before data reaches the MCP server, ensuring sensitive information does not hit external APIs or the LLM. No 'eval' or direct command injection vulnerabilities are apparent in the provided server code. The MCP server explicitly validates the tool name ('expense-policy_submitExpense') before execution, preventing arbitrary tool calls. The HTTP mode, designed for testing, uses a permissive CORS policy (allowing all origins), which would be a security risk if exposed publicly in a production environment, but is acceptable for its stated local testing purpose. No hardcoded secrets were found.
