Security Report

4.2
Use Caution4.2High Risk

This MCP server provides a well-intentioned wrapper around Modal's CLI with generally sound architecture. The server properly shells out to the local `modal` CLI rather than reimplementing auth, and implements path-traversal protections via an opt-in allowlist for sensitive file operations. However, several medium-severity concerns exist: the server can execute arbitrary local Python code via `deploy` and `run` tools (though documented as requiring tool-approval), secret redaction is applied inconsistently (missing from exception handling in some paths), and there is minimal input validation on user-supplied parameters despite the server's broad filesystem and execution capabilities. Supply chain analysis found 8 known vulnerabilities in dependencies (0 critical, 3 high severity). Package verification found 1 issue.
