Feature & Specification Comparison

Specification	Aegis Acacian Security	Jamjet Policy jamjet-labs Security
Summary	Policy-based governance for AI agent tool calls. YAML policies, approval gates, risk assessment, and audit logging. Cross-platform: LangChain, OpenAI, Anthropic, MCP.	MCP stdio interceptor (@jamjet/mcp-shim) that applies one YAML policy file (block / requireapproval / audit / budget cap) to tools/call requests before they reach the real MCP server. The same policy also runs in Claude Code PreToolUse hooks (@jamjet/claude-code-hook), OpenAI Agents SDK guardrails (@jamjet/openai-guardrail), and JamJet's Python/TS SDKs — jamjet audit show tails every decision across every adapter from /.jamjet/audit/.
