MCP server for MCP Scraper web intelligence tools
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe only agent-control change is an explicit, first-party CLI flag that registers this package's own Claude Code MCP server. There is no install-time hook, hidden exfiltration, or foreign control-surface write, so the capability is a warning rather than a publish block.
Static reason
High-risk behavior combination matched malicious policy.; previous stored version diff introduced dangerous source
Trigger
Explicit user command: mcp-scraper-cli agent install claude --apply, with MCP_SCRAPER_API_KEY or --api-key set.
Impact
The user's Claude Code user scope gains or replaces an mcp-scraper server entry that can start this package and receive the provided API key. Other hosts only receive printed config text.
Mechanism
The CLI spawns claude mcp remove and then claude mcp add --scope user, passing MCP_SCRAPER_API_KEY and npx -y --package mcp-scraper@latest mcp-scraper.
AI rationale
The only agent-control change is an explicit, first-party CLI flag that registers this package's own Claude Code MCP server. There is no install-time hook, hidden exfiltration, or foreign control-surface write, so the capability is a warning rather than a publish block.
Evidence
dist/bin/mcp-scraper-cli.jspackage.json
Decision evidence
public snapshotAI called this Suspicious at 78.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- The mcp-scraper-cli agent install --apply command upserts a user-scope Claude Code MCP server named mcp-scraper by spawning the claude CLI, including a prior remove of that entry.
- The registration command is npx with --package defaulting to mcp-scraper@latest and places the caller API key in MCP_SCRAPER_API_KEY.
- --apply is limited to the claude host and refuses to run without an API key.
- package.json publishes mcp-scraper-cli as a bin entry; install mutation is not an npm lifecycle hook.
Evidence against
- package.json has no preinstall, install, or postinstall script.
- --apply is an explicit CLI flag, not import-time or install-time execution.
- The registration targets this package's own MCP server rather than a foreign agent control file.
- Library entry dist/index.cjs exports harvest helpers and does not self-execute a network payload on load.
