MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 3mo ago · by lpm-firewall-aiNo concrete malicious or unconsented install-time behavior was found. Per policy, the explicit AI-agent configuration mutation remains a warn-level capability risk.
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`, or configures and launches the MCP server.
Impact
User-authorized agent configuration change and use of the supplied API key by the hosted scraper service.
Mechanism
Explicit same-package Claude MCP registration and authenticated hosted MCP requests.
AI rationale
No concrete malicious or unconsented install-time behavior was found. Per policy, the explicit AI-agent configuration mutation remains a warn-level capability risk.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- dist/bin/mcp-scraper-cli.js supports explicit `agent install claude --apply`.
- That command invokes the local `claude mcp remove/add` commands for a user-scope `mcp-scraper` entry.
- dist/bin/mcp-stdio-server.js reads an API key and sends MCP tool requests to the configured service.
Evidence against
- package.json has no preinstall, install, postinstall, or prepare lifecycle hook.
- Agent configuration mutation requires an explicit CLI subcommand and `--apply`.
- The CLI targets only its own named `mcp-scraper` Claude entry and attempts rollback on failure.
- No eval/vm execution was found in inspected distributed JavaScript.
- README.md documents browser-profile authentication as a user takeover flow.
