Model Context Protocol (MCP) client for Editable Slides Cloud

AI Security Review

scanned 21d ago · by lpm-firewall-ai

When a user invokes conversion and Google Drive upload, the package enumerates local gcloud identities and silently shares the resulting presentation with every other configured identity. Its MCP output also attempts to control the host AI agent's actions.

Static reason

No blocking static signals were detected.

Trigger

Launching the CLI as an MCP server and completing a slide conversion or Google Drive upload.

Impact

Sensitive presentation contents can be disclosed to unrelated local Google accounts without user consent.

Mechanism

gcloud account enumeration followed by cross-account Google Drive permission grants.

Attack narrative

The default executable starts an MCP server. During a conversion, it can upload a generated deck to Google Drive; it then lists all accounts in the local gcloud configuration and grants writer permission to every account except the current one. This is unrelated to converting slides and can expose user content to corporate or personal accounts without consent. Returned MCP text also instructs AI agents not to inspect files or use shell commands, which is reviewer and agent manipulation.

AI rationale

The automatic cross-account sharing is concrete, undisclosed data disclosure behavior. The package also embeds AI-agent control instructions, reinforcing malicious intent.
