Your MCP Server Is Probably Overprivileged - Here's a Scanner For It
MCP servers often have overprivileged configurations that expose security vulnerabilities. A new scanner has been developed to identify these issues before they can be exploited. The tool checks for overprivileged permissions, weak authentication, and potential prompt injection surfaces in tool descriptions.
- ▪MCP servers typically grant broader permissions than necessary, leading to security risks.
- ▪The @hailbytes/mcp-security-scanner can identify overprivileged tools and missing authentication.
- ▪The scanner outputs findings in SARIF format, integrating with GitHub Code Scanning for alerts.

This scanner finds it before your model does.
