New tool audits MCP servers, finds widespread auth gaps

By PulseAugur Editorial · [1 sources] ·

A new command-line tool, patchbay audit, has been developed to assess the security of Model Context Protocol (MCP) servers. The tool scans 25 public MCP servers, revealing that many are not fully implementing the expected OAuth 2.1 security standards. While some servers, like Chainflip's, are intentionally public-by-design, others have critical security findings related to missing authentication or inadequate scope management. AI

IMPACT Highlights potential security vulnerabilities in emerging MCP server implementations, urging developers to adopt stronger authentication practices.
