Verified publisher — Model Context Protocol
This package is from Model Context Protocol, a verified publisher. Official MCP specification and SDKs. The findings below are expected for this type of tool — for example, a payment SDK will read API keys, and a browser tool will use child_process. These patterns are normal for a verified publisher, not signs of malice.
