Security Report
This is a thin MCP client that forwards document validation requests to the hosted ValidaLatam API (directly or via RapidAPI) and contains no local validation logic, shell execution, or file access. The only sensitive data is an optional RAPIDAPI_KEY read from the environment, which is handled appropriately, and the outbound network traffic matches the server's stated purpose. Minor observations include the lack of input validation on the generate_test_data type path parameter and the fact that submitted document values (personal tax IDs) are sent to a third-party host. Supply chain analysis found 5 known vulnerabilities in dependencies (0 critical, 5 high severity). Package verification found 1 issue.
