MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiNo source evidence shows covert installation, credential harvesting, or unconsented persistence. The explicit agent-config mutation and persistent authenticated browser capability merit a warning as a dangerous user-invoked capability.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
A user runs the agent install command with --apply or invokes browser-profile MCP tools.
Impact
A user-authorized agent can gain this package's web and authenticated-browser capabilities; the package receives its configured service API key during runtime.
Mechanism
Explicit agent configuration registration and hosted browser-profile persistence.
AI rationale
No source evidence shows covert installation, credential harvesting, or unconsented persistence. The explicit agent-config mutation and persistent authenticated browser capability merit a warning as a dangerous user-invoked capability.

Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- An explicit CLI command can replace the user's Claude Code MCP entry with this package.
- The MCP server supports hosted browser profiles that retain cookies and storage for logged-in sites.
- When the stdio server runs, it sends the configured API key to the configured service URL.
Evidence against
- The manifest has no npm install lifecycle hook.
- Agent configuration mutation requires the user to invoke the CLI with --apply and provide an API key.
- Profile login is described as a fresh user sign-in; existing browser cookies are not imported.
