mcp-scraper@0.102.6
Authenticated public client for hosted MCP Scraper tools and REST APIs
AI Security Review
scanned 4d ago · by lpm-firewall-aiThe CLI sends local artifact paths and workflow metadata to the vendor’s service whenever it records workflow artifacts. This is identifying runtime telemetry without a clear disclosure or opt-out, so warn rather than block; the inspected payload does not include artifact contents or unrelated credentials.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
A user runs a CLI workflow that creates or remembers an artifact.
Impact
The service receives local path information and workflow metadata. The inspected payload does not include artifact contents or credentials from other services.
Mechanism
The CLI POSTs a workflow title, local artifact path, and workflow/run identifiers to `/memory/mcp-call`, authenticating with `MCP_SCRAPER_API_KEY`.
AI rationale
The CLI sends local artifact paths and workflow metadata to the vendor’s service whenever it records workflow artifacts. This is identifying runtime telemetry without a clear disclosure or opt-out, so warn rather than block; the inspected payload does not include artifact contents or unrelated credentials.
Evidence
dist/bin/mcp-scraper-cli.js${MCP_SCRAPER_OUTPUT_DIR}/workflows/<workflow>/... (default output directory: ~/Downloads/mcp-scraper)
Network endpoints1
mcpscraper.dev/memory/mcp-call (default; configurable with MCP_SCRAPER_BASE_URL)
Decision evidence
public snapshotAI called this Suspicious at 87.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- When the sink runs, the CLI POSTs JSON to `/memory/mcp-call` with the API key in the `x-api-key` header.
- Artifact handling sends a workflow title, the artifact’s local path, and workflow/run identifiers to that sink.
- The sink is called while an explicit CLI workflow action runs; no install hook is configured.
Evidence against
- The default destination is the package’s own service, and the API key is the package’s own key.
- The payload includes the artifact path and metadata, not the artifact’s file contents.
- The package has no lifecycle scripts; the flagged behavior is runtime CLI functionality.
