MCP Shield Overview

The rob925/mcp-shield MCP server scans local MCP servers and AI agent projects for common security risks. It runs as a Python CLI or stdio MCP server, exposing tools to scan a path and list detection rules. Findings can be emitted as text, JSON, Markdown, or SARIF, with severity thresholds for CI failure. Reach for it before deployment or in pull-request checks when you need heuristic checks for secrets, process execution, environment access, risky tool descriptions, and prompt-injection phrases.

Primary Use Cases for MCP Shield:
  • Scan an MCP project before deployment
  • Gate pull requests on high-severity findings
  • Export SARIF results for GitHub code scanning
  • Review tool descriptions for risky language
