Mastra Code SDK: the agent core behind Mastra Code (everything except the TUI) — build your own UIs and surfaces on top of it
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe published package is a Mastra Code agent library with no npm lifecycle hook and no self-executing entrypoint. Shell use, local settings writes, and optional telemetry are reached only through caller-invoked SDK APIs that match that product.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A caller invokes exported functions such as createMastraCodeAgentController or settings helpers.
Impact
Effects stay within the coding-agent session the application starts. No unconsented install mutation or hidden exfiltration path was found.
Mechanism
Those functions load local project settings, provider credentials, and optional product telemetry for the Mastra Code agent the caller is running.
AI rationale
The published package is a Mastra Code agent library with no npm lifecycle hook and no self-executing entrypoint. Shell use, local settings writes, and optional telemetry are reached only through caller-invoked SDK APIs that match that product.
Decision evidence
public snapshotAI called this Clean at 88.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- package.json has no preinstall, install, or postinstall scripts; its scripts are only build, typecheck, test, and lint.
- The published entry dist/index.js exports a caller-invoked Mastra Code agent factory and does not execute that factory at import or install time.
- Settings persistence writes settings.json under the package app-data directory only when settings APIs run.
Evidence against
- Shell, LSP, hook, and clipboard helpers use child_process only from explicit coding-agent features.
- Optional PostHog telemetry is created by createMastraCodeAnalytics and can be turned off with MASTRA_TELEMETRY_DISABLED.
