Analysis finds 99.9% of MCP servers untestable in production

A recent analysis of 22,561 Multi-Agent Conversation Protocol (MCP) servers revealed a significant trust gap, with only 18 servers being independently verifiable at runtime. The dominant method of vetting these servers relies on static code scans, which do not assess the actual behavior or reliability of the live service. This leaves a vast majority of MCP servers as black boxes, making it difficult for agents to ensure the tools they call are dependable and secure against runtime attacks like tool poisoning. AI

IMPACT Highlights critical security and reliability gaps in the agent tool ecosystem, pressuring developers to implement runtime verification.
