# Sovereign MCP — Deterministic MCP Security Architecture **FrozenNamespace as Root of Trust for Model Context Protocol Tool Verification** *Sovereign Shield / Mattijs Moens — March 2026* --- ## The Problem MCP (Model Context Protocol) has become the standard for connecting AI agents to tools. But the protocol has fundamental security gaps that no amount of patching will fix without an architectural solution. **The 10 biggest MCP vulnerabilities today:** 1. **No authentication by default.** 78% of public MCP implementations have no proper authorization. Anyone who can reach the endpoint can invoke any tool. 2. **Tool description poisoning.** Malicious content embedded in MCP tool descriptions gets read by the model during tool discovery. The model trusts descriptions as instructions. An attacker can manipulate agent behavior just by modifying a tool's description field. 3. **Prompt injection via tool responses.** A compromised MCP tool returns prompt injection payloads in itsRead full README on GitHub →
