AgentValet vs Jamjet Policy
In-depth architectural comparison of the AgentValet and Jamjet Policy MCP servers. Compare execution transports, security boundaries, tool capabilities, quality scores, and ready-to-paste client installation snippets for Claude, Cursor, Windsurf, and VS Code.
At a Glance & Executive Verdict
AgentValet
Security · Local stdio
Quality: 49/100 (Fair) | Auth: API Key required
Jamjet Policy
Security · Local stdio
Quality: 45/100 (Fair) | Auth: No auth required
Verdict Summary: Choose AgentValet if you need specialized Security tools running via a local process. Choose Jamjet Policy if your workspace requires Security integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose AgentValet when:
You need dedicated capabilities in the Security domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: API Key required (Freemium).
You have access to required keys: AGENT_ID, OWNER_ID, PROXY_URL, AGENT_PRIVATE_KEY_PATH.
Primary tools included: Per-agent RS256 cryptographic identity with SPIFFE URIs, 60-second signed JWTs for each request, Deny-by-default granular scope grants per agent/platform/action.
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.
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/.
