MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiSource inspection found an explicit, user-invoked agent configuration mutation and an unpinned runtime self-package reference, but no automatic lifecycle hook or concrete secret theft. This warrants a warning rather than a publish block.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
The user runs mcp-scraper-cli agent install claude --apply.
Impact
A future latest release can run when the configured MCP server starts.
Mechanism
Explicit AI-agent configuration mutation with an unpinned self-package launcher.
AI rationale
Source inspection found an explicit, user-invoked agent configuration mutation and an unpinned runtime self-package reference, but no automatic lifecycle hook or concrete secret theft. This warrants a warning rather than a publish block.
Evidence
dist/bin/mcp-scraper-cli.js
Decision evidence
public snapshotAI called this Suspicious at 84.0% confidence as Unknown with low false-positive risk.
Evidence for warning
- The explicit agent-install command recommends an unpinned mcp-scraper@latest package.
- The --apply path runs Claude CLI commands that replace the user-scope mcp-scraper registration.
Evidence against
- package.json has no preinstall, install, or postinstall lifecycle hook.
- The configuration mutation requires an explicit CLI command and --apply flag; no automatic install-time action was found.
- The inspected hosted API code sends its configured API key to the package's default mcpscraper.dev endpoint.
