AI Security Review
scanned 6d ago · by lpm-firewall-aiThe postinstall hook automatically changes the consumer project’s agent configuration to enable this package’s own MCP server, creating a residual integration risk. The inspected server registration exposes component information tools, with no evidence here of broader control or data exfiltration.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Installing the package runs its postinstall hook, unless the documented environment opt-out is set.
Impact
The agent may load the package’s component information tools after restart without a separate setup command.
Mechanism
The hook writes or updates the exosphere entry in the project’s .mcp.json to launch this package’s MCP server.
AI rationale
The postinstall hook automatically changes the consumer project’s agent configuration to enable this package’s own MCP server, creating a residual integration risk. The inspected server registration exposes component information tools, with no evidence here of broader control or data exfiltration.
Evidence
package.jsonscripts/postinstall-mcp.jsdist/mcp-server/index.js.mcp.json
Decision evidence
public snapshotAI called this Suspicious at 91.0% confidence as Dangerous Capability with medium false-positive risk.
Evidence for warning
- package.json runs scripts/postinstall-mcp.js during postinstall.
- The installer targets the project’s .mcp.json and registers this package’s MCP server.
- The installer can add or update the entry automatically; an environment opt-out is available.
- The registered server exposes component information tools, consistent with this package’s UI component library.
Evidence against
- The inspected MCP setup registers the package’s own server and component tools; the reviewed excerpts show no foreign server registration or data export.
