MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is not malicious install-time behavior, but the explicit agent configuration command creates a real ongoing capability and resolves to a mutable latest release. The package should be warned rather than blocked.
Static reason
One or more suspicious static signals were detected.
Trigger
The user runs mcp-scraper-cli agent install claude --apply with an API key.
Impact
A user can be configured to launch a future registry release of this MCP server from Claude Code.
Mechanism
Explicit user-command MCP configuration mutation.
AI rationale
This is not malicious install-time behavior, but the explicit agent configuration command creates a real ongoing capability and resolves to a mutable latest release. The package should be warned rather than blocked.
Evidence
dist/bin/mcp-scraper-cli.js
Decision evidence
public snapshotAI called this Suspicious at 86.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- The explicit CLI command `agent install claude --apply` removes and re-adds a user-scope Claude MCP server.
- The generated server command uses `npx` with the default package spec `mcp-scraper@latest`, allowing a later registry release to run when the configured agent starts.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- The configuration mutation requires a user to invoke the CLI and pass --apply.
- The inspected browser and network code implements the package's web-scraping and hosted-service features; no credential redirection or covert exfiltration was confirmed.
