Mastra Temporal workflows integration - run Mastra workflows on the Temporal durable execution platform

AI Security Review

scanned 2d ago · by lpm-firewall-ai

The manifest has no install lifecycle hook, and inspected runtime behavior matches the advertised Temporal adapter and caller-invoked worker build. The flagged module loading and file writes are tied to project workflow transformation and generated artifacts; no malicious behavior was identified.

Static reason

No blocking static signals were detected.

Trigger

Workflow actions occur when callers use the adapter; bundling occurs when a caller invokes worker prebuild with a project entry file.

Impact

The inspected behavior supports the package’s workflow and build functions; no unauthorized data transfer or other attack effect was found.

Mechanism

The worker transforms workflow source and writes generated artifacts to the project cache, then loads its generated activity module.

AI rationale

Evidence

node_modules/.mastra

Decision evidence

public snapshot

AI called this Clean at 94.0% confidence as Benign with low false-positive risk.

Evidence for AI clean decision

package.json exposes the adapter and worker entry points; its scripts are limited to build, test, lint, and typecheck, with no install lifecycle hook.
The runtime starts workflows through the supplied Temporal client, using the configured task queue and workflow arguments.
The worker transforms project workflow source and writes generated files under the project’s `.mastra` cache during an explicit prebuild call; its activity import uses the generated module path.
The declared Babel dependencies and inspected source implement parsing, AST utilities, and source-map handling consistent with the worker’s transformation tasks.
