Security Report

4.6

Use Caution4.6High Risk

The provided files show a New Relic observability MCP server for AI coding assistants, with no hardcoded secrets, shell injection, exfiltration logic, or obfuscated code in the visible content. The main concerns are that the local dashboard API shows no visible authentication and that the server reads developer session transcripts, so sensitive-data handling could not be fully verified from these excerpts. The core source files (src/index.ts, hooks, and the network exporters) were not included, so this score reflects partial visibility. Supply chain analysis found 6 known vulnerabilities in dependencies (0 critical, 2 high severity). Package verification found 1 issue.
