VerifiedMCP tools are essentially arbitrary code execution, indirect prompt injection is a real-world threat, and attack vectors can be hidden in resource content rather than in direct user input.71% similarUnverifiedMCP 的在线发现机制是其区别于传统 function calling 方案的核心架构差异，使智能体在运行时动态了解可用能力而无需在训练阶段预先编码70% similarUnverifiedMCP only specifies "how to expose tools," not "when which tool should be called"—this is precisely the root cause, repeatedly emphasized in the article, of why the implicit operational rules cannot be solved by the protocol.69% similarUnverifiedBefore MCP appeared, there were multiple mutually incompatible integration specifications such as LangChain Tools and OpenAI Function Calling, causing ecosystem fragmentation.69% similarUnverifiedHindsight provides APIs and SDKs, and supports MCP, allowing save, retrieval, and reflection functions to be exposed as Agent tools via MCP.68% similar
