MCP Has No Security Layer. We Built One -- MCPS.

MCP (Model Context Protocol) is the standard for connecting AI agents to external tools. Anthropic built it. OpenAI adopted it. Google, Microsoft, and AWS ship MCP integrations. 146 members under the Agentic AI Foundation. Thousands of MCP servers in the wild. One problem: none of it is secured. Every tool call between an AI agent and an MCP server travels without integrity verification. No replay protection. No way to verify that a tool definition hasn't been silently modified since you approved it. A compromised proxy can rewrite tool parameters after TLS termination and neither side knows. This isn't theoretical: OWASP lists tool poisoning as MCP-01 in their MCP Top 10 38% of scanned MCP servers lack authentication entirely 30 CVEs filed in 60 days Critical RCE in the official MCP Inspector tool (CVE-2025-6514, CVSS 9.6) Why TLS and OAuth Are Not Enough TLS protects the transport. It terminates at every hop. Corporate HTTPS inspection proxies (Zscaler, Palo Alto, Fortinet) routinely
