Security Report

5.8

Moderate5.8Moderate Risk

esp32sim-mcp is a local stdio MCP server that drives a local ESP32 emulator with no credentials required, which fits its purpose. Findings are minor: tool arguments that name file paths are passed through without validation, the agent config setup writes to user-level config files, and the MCP entry point uses an unpinned npx -y fetch. The provided init.ts is truncated, so its upsert and write logic could not be fully reviewed. Supply chain analysis found 2 known vulnerabilities in dependencies (1 critical, 0 high severity). Package verification found 1 issue.
