McpVanguard

security proxyMCP enforcementdeterministic guardrails

McpVanguard is a security proxy designed specifically for the Model Context Protocol (MCP). It interposes between AI agents and tool servers to enforce non-bypassable security policies.

THE PROXY REQUIREMENT

Direct connections between agents and tools are inherently dangerous. McpVanguard provides the 'Execution Boundary' needed to safely deploy powerful agents in production environments, ensuring every action is inspected and governed.

TECHNICAL ARCHITECTURE

Built in Rust for maximum performance and memory safety, McpVanguard implements a deterministic rules engine that evaluates tool calls against versioned YAML manifests at sub-millisecond latency.

ProvnAI Mitigation

By centralizing enforcement at the network boundary, McpVanguard eliminates the need to rely on model-level self-correction or disparate server-side validations.
