MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package has an explicit, first-party AI-agent configuration capability but no install hook or confirmed credential redirection to an unrelated host. Under the stated policy this warrants a warning rather than a block.
Static reason
One or more suspicious static signals were detected.; previous stored version diff introduced dangerous source
Trigger
User runs `mcp-scraper-cli agent install claude --apply`.
Impact
The configured Claude client will subsequently launch mcp-scraper with its supplied API key.
Mechanism
explicit first-party Claude MCP registration via the Claude CLI
AI rationale

Decision evidence
public snapshotAI called this Suspicious at 90.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- Explicit `agent install ... --apply` registers a user-scope Claude MCP server.
- The applied server runs this package through `npx` and includes the supplied API key in its environment.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- Agent configuration is only mutated after the user explicitly runs `agent install claude --apply`; Codex and Claude Desktop paths only print configuration.
- The MCP endpoint defaults to the package-aligned mcpscraper.dev host; no fixed unrelated credential gateway was confirmed.
