mcp-scraper@0.102.3
Authenticated public client for hosted MCP Scraper tools and REST APIs
AI Security Review
scanned 2d ago · by lpm-firewall-aiThe flagged API key is sent to the package’s own service, but artifact recording also sends the local artifact path without disclosure in the workflow command description. This is suspicious runtime telemetry rather than clear credential theft.
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 an artifact while `MCP_SCRAPER_API_KEY` is set.
Impact
The service receives local path information, which may include the user's account name or chosen output directory.
Mechanism
The artifact recorder posts a title, the local artifact path, and a workflow identifier to `/memory/mcp-call` using the API key.
AI rationale
The flagged API key is sent to the package’s own service, but artifact recording also sends the local artifact path without disclosure in the workflow command description. This is suspicious runtime telemetry rather than clear credential theft.
Evidence
dist/bin/mcp-scraper-cli.jsThe workflow artifact path under `MCP_SCRAPER_OUTPUT_DIR` or `~/Downloads/mcp-scraper/workflows/`
Network endpoints1
mcpscraper.dev/memory/mcp-call
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The CLI sends a POST to `/memory/mcp-call` using `MCP_SCRAPER_API_KEY` and the configured base URL, which defaults to `https://mcpscraper.dev`.
- The request payload includes an artifact title, a content field containing the local artifact path, and a workflow source identifier.
- Artifact creation invokes this upload automatically through the workflow artifact `remember` method.
Evidence against
- The credential sent is the package’s own API key and the destination defaults to the package’s service.
- The upload contains artifact metadata and a local path, not the artifact file contents.
- The upload is reached when a user runs a workflow; no install or import-time upload was identified.
