AI Security Review
scanned 3d ago · by lpm-firewall-aiThe flagged credential handling matches the app’s OAuth and signup-notification behavior: Google tokens go to Google, and signup details go to Slack only when the server has a configured Slack bot token. The manifest has no install lifecycle hook, and CLI setup is performed through an explicit install command.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
OAuth user-info lookup follows an authentication callback; Slack notices follow signup events when a Slack bot token is configured; CLI installation runs with the explicit install command.
Impact
No malicious impact identified. Configured Slack receives account signup notices as part of the service’s signup handling.
Mechanism
The app sends OAuth access tokens to Google’s user-info endpoint and posts signup notices to Slack using SIGNUP_SLACK_BOT_TOKEN. The CLI checks package version metadata and can install this package into its MCP directory.

The flagged credential handling matches the app’s OAuth and signup-notification behavior: Google tokens go to Google, and signup details go to Slack only when the server has a configured Slack bot token.

Decision evidence
public snapshotAI called this Clean at 91.0% confidence as Benign with low false-positive risk.
Evidence for AI clean decision
- The manifest defines CLI binaries and a test script, with no install lifecycle hook.
- Signup notifications use a server-configured Slack token and post to Slack’s API.
- Google OAuth access tokens are sent to Google’s user-info endpoint.
- The MCP install and configuration steps run under the explicit `install` command.
- The CLI’s npm install command installs this package itself into its MCP directory.
Evidence against
- The Slack notifications include signup details and target a hard-coded alerts channel, but are called as part of signup handling and require the operator-configured Slack token.
- The app starts an hourly signup rollup when created; it returns without sending if the Slack token is absent.
- The CLI checks npm for a newer package version on startup, but the request is limited to the package’s version metadata.
