MCP Shield Overview

The muhannad-hash/mcp-shield MCP server scans npm packages and local MCP server directories for malicious patterns before installation. It also checks tool descriptions or responses for prompt injection and audits npm package trust indicators, dependency CVEs, maintainers, and age. npm packages are installed with scripts disabled during analysis, while JavaScript and TypeScript files are checked against attack signatures. Reach for it when reviewing an unfamiliar MCP server, package, or tool response before allowing access to sensitive context or credentials.

Primary Use Cases for MCP Shield:
  • Scan an npm MCP package before installing it
  • Inspect a cloned MCP server directory
  • Check tool descriptions for prompt injection
  • Audit an npm package's supply-chain trust
