MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe package has an explicit user-invoked agent configuration capability and handles an API key for its hosted service, so it warrants a warning. Direct inspection found no lifecycle execution or concrete malicious chain.
Static reason
One or more suspicious static signals were detected.
Trigger
The user runs `mcp-scraper-cli agent install claude --apply` or starts the MCP server with a configured key.
Impact
It can alter the named MCP client entry and make that client launch this package; credentials are sent to the configured package service.
Mechanism
Explicit user-command MCP registration and authenticated hosted MCP requests.
AI rationale
The package has an explicit user-invoked agent configuration capability and handles an API key for its hosted service, so it warrants a warning. Direct inspection found no lifecycle execution or concrete malicious chain.

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` invokes Claude CLI commands to replace the user-scope `mcp-scraper` server registration.
- The stdio server reads its configured API key and sends it as `x-api-key` to the package's configured hosted MCP endpoint.
- The CLI can read a key from `~/.mcp-scraper-key` when the user runs its doctor or server commands.
Evidence against
- package.json contains no preinstall, install, or postinstall lifecycle hook.
- The installer binary only prints installation guidance.
- Agent configuration mutation is gated behind an explicit user CLI command and limited to the named `mcp-scraper` Claude entry.
- The inspected network authentication is directed to the package's default mcpscraper.dev service; no hidden credential exfiltration endpoint was confirmed.
