Feature & Specification Comparison

Specification	Shield AperionAI Security	Dcl Webhook Fronesis-Labs Security
Summary	Local guardrail proxy for AI coding agents. Wraps any MCP server (stdio or Streamable HTTP) and blocks destructive tool calls — DROP TABLE, rm -rf, force-push — before they execute. MCP supply-chain protection: TOFU tool-catalog pinning against rug pulls, plus tool-description and tool-result scanning for tool poisoning and prompt injection. 51 starter rules, approval gates, audit logging. Single binary, Apache-2.0.	Deterministic AI audit layer: evaluates LLM/agent outputs against configurable policies (jailbreak, safety, quality, wallet, trade, MEV compliance) and writes every verdict to a tamper-evident SHA-256 hash chain — metadata only, never raw content. 17 tools including a full crypto-trading compliance suite. Pay-per-call via x402 (USDC on Base), from $0.01. mcp.fronesislabs.com/mcp
