MCP security scanner and CI gate. Test, secure, and monitor MCP servers with attack simulation, schema drift detection, health scoring, and SARIF before agents depend on them.
AI Security Review
scanned 1mo ago · by lpm-firewall-aiNo concrete malware behavior was found, but project mutation, telemetry collection, and an npx fallback create material runtime and privacy risk. The lifecycle write is guarded by consumer-controlled auto-setup, so blocking publication is not justified.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; previous stored version diff introduced dangerous source
Trigger
Install in an MCP project with autoSetupCi enabled, or run the CLI with telemetry enabled by its policy or configuration.
Impact
Adds CI automation and may disclose telemetry metadata to the vendor; no install-time secret theft or remote payload execution was confirmed.
Mechanism
Conditional project workflow creation and consent-gated telemetry delivery.
AI rationale
No concrete malware behavior was found, but project mutation, telemetry collection, and an npx fallback create material runtime and privacy risk. The lifecycle write is guarded by consumer-controlled auto-setup, so blocking publication is not justified.

Decision evidence
public snapshotAI called this Suspicious at 82.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The package runs a postinstall script.
- With an opt-in project setting or environment flag, postinstall creates a scheduled GitHub Actions workflow in the consumer project.
- CLI telemetry has a vendor endpoint, reads hostname and Git identity, and can send event data there.
- A terminal rendering check can invoke npx to obtain another package when it is absent.
Evidence against
- The postinstall script exits unless auto-setup is explicitly enabled and performs no network request or shell execution.
- Telemetry defaults to prior consent and provides opt-out controls.
- No self-dependency, hidden payload, or install-time credential exfiltration was found.
- The flagged scanner files implement security scanning, report helpers, and risk-graph processing rather than a payload.
