Feature & Specification Comparison

Specification	Jamjet Policy jamjet-labs Security	AgentValet AgentValet Security
Summary	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/.	Identity and credential governance broker for MCP servers. Issues scoped, short-lived credentials per agent to stop credential inheritance. Audit log, human approval gates, AIMS-aligned.
