MCP endpoints expose sensitive data, lack security controls · 2 sources tracked

By PulseAugur Editorial · [2 sources] ·

A recent security analysis of 78 public Model Context Protocol (MCP) endpoints revealed significant vulnerabilities, with 74% exposing their full tool lists to anonymous users. The analysis highlighted issues such as unauthenticated 401 errors, mixed protocol versions leading to interoperability problems, and tool descriptions that could be poisoned to manipulate AI agents. These findings underscore the need for robust security measures, including least privilege access, human approval for critical actions, and treating all tool-returned text as untrusted to mitigate risks like prompt injection and secret leakage.
