Why it matters

MCP server weaknesses can expose agent-connected systems and credentials, making authentication, connector review, and tightly scoped tool permissions important defensive priorities.

Bonfy's MCP security overview compiles third-party audits reporting widespread server vulnerabilities and authentication weaknesses, including OAuth adoption of only 8.5% among more than 5,200 surveyed servers. The article also describes the Deadbugz supply-chain campaign, whose malicious MCP server reportedly behaves normally for three tool calls before changing its instructions to seek SSH keys and cloud credentials.
