MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is not malicious under the install-control-surface policy because the configuration mutation is explicit and limited to the package's own Claude MCP entry. It merits a warning because that command can enable an agent extension and place a supplied service key into its configuration.
Static reason
One or more suspicious static signals were detected.
Trigger
The user runs `mcp-scraper-cli agent install claude --apply` with an API key.
Impact
The package can become an enabled MCP server in Claude Code and receive the configured package API key.
Mechanism
Explicit Claude Code MCP registration through the local Claude CLI.
AI rationale
This is not malicious under the install-control-surface policy because the configuration mutation is explicit and limited to the package's own Claude MCP entry. It merits a warning because that command can enable an agent extension and place a supplied service key into its configuration.

Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with low false-positive risk.
Evidence for warning
- An explicit CLI command can replace the user's Claude Code MCP server entry with this package.
- The replacement includes an MCP Scraper API key and starts the package through npx.
Evidence against
- package.json has no preinstall, install, or postinstall hook.
- The agent configuration change requires the user to run `agent install claude --apply`; other hosts only receive printed instructions.
- The hosted API key is sent only to the package's configured service endpoint during user-invoked CLI operations.
