riseandignite/mcp-shield is a security scanner that inspects installed MCP server configurations to find risks tied to tools. The repository presents itself as a security scanner for MCP servers, and the README summary names tool poisoning, data exfiltration paths, and cross-origin privilege escalation detection. It is written in TypeScript and uses the MIT license. The repository was created on April 15, 2025, and has 555 GitHub stars.
The configuration files it scans are MCP and Claude Desktop settings. A user can point it at a specific file, so it covers settings from both environments. The detection items are risks that arrive through tools, such as tool poisoning, paths along which data can leak out, and problems where privileges escalate across different origins. Analysis using Anthropic Claude is optional, and it also supports a list of servers to exclude from the scan. The point is therefore not to describe every behavior of the servers themselves, but to find such risk signals in the configuration.
The provided information does not list a latest release, and it gives no detection accuracy or performance in real environments. What can be confirmed is limited to the scan of a specified MCP or Claude Desktop configuration and the risk types enumerated in the documentation. The utility of this tool should therefore sit in configuration review, and its results alone are not enough to judge the overall security state of a server.
