VerifiedThe MCP protocol itself does not carry risk semantics for tools, and the responsibility for security judgment falls back on the application developers.74% similarUnverifiedThe MCP intermediate layer introduces additional deployment complexity, but establishes an isolation barrier between the Agent and sensitive credentials, representing a trade-off between developer experience and security boundaries72% similarUnverifiedUnlike AgentReach, an MCP server exposes a unified protocol endpoint as an intermediate layer, meaning every call must pass through that intermediate layer, which can become a performance bottleneck or single point of failure.72% similarUnverifiedAC2 is positioned as a security supplementary layer for protocols such as MCP rather than a replacement, used to fill the gaps in existing agent protocols in the dimension of security governance.71% similarUnverifiedSince the direction of protocol evolution is largely determined by Anthropic, whether MCP can truly remain neutral toward model vendors remains a subject of debate.71% similar
