Security audit

PDF Batch Processing Tool

Security checks across malware telemetry and agentic risk

Overview

This is a local PDF utility whose file access and dependencies fit its stated purpose, though users should treat untrusted PDFs carefully and note that some advertised features are not implemented.

Install only if you need local merge, split, rotate, or text-extraction workflows. Use an isolated Python environment, pin current patched dependency versions if possible, and avoid processing PDFs from untrusted sources without sandboxing or resource limits. Do not rely on the advertised image extraction or compression features unless the publisher adds matching scripts.

MCP Least Privilege
Confidence
89% confidence
Finding
The skill describes reading and writing local files but does not declare any permissions, which creates a transparency and policy-enforcement gap. In an agent environment, undeclared file access can lead to processing unintended files, overwriting outputs, or bypassing user expectations about what the skill is allowed to touch.
