MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package contains a guarded first-party MCP registration feature, not a lifecycle-driven or stealthy malicious chain. Policy calls for a warning for explicit user-command agent configuration mutation.
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 with an API key.
Impact
Enables the package’s MCP capabilities in the user’s Claude Code environment.
Mechanism
User-gated Claude MCP configuration replacement
AI rationale
The package contains a guarded first-party MCP registration feature, not a lifecycle-driven or stealthy malicious chain. Policy calls for a warning for explicit user-command agent configuration mutation.
Evidence
package.jsondist/bin/mcp-scraper-cli.cjsClaude Code user-scope MCP configuration (via claude CLI)
Decision evidence
public snapshotAI called this Suspicious at 89.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- Explicit CLI --apply path registers an MCP server in Claude Code’s user scope.
- The apply path invokes Claude commands to remove and add only the named mcp-scraper entry.
Evidence against
- package.json has no preinstall, install, postinstall, or prepare lifecycle hook.
- Agent configuration mutation is guarded by a user-supplied CLI command and --apply flag.
- No fixed credential-exfiltration gateway or import-time persistence was confirmed in inspected code.
