Feature & Specification Comparison

Specification	Platform sidclawhq Security	Jamjet Policy jamjet-labs Security
Summary	Governance proxy for MCP servers. Wraps any upstream server with policy evaluation, human approval workflows, and hash-chain audit trails. 18+ framework integrations. Apache 2.0 SDK.	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/.
