Feature & Specification Comparison

Specification	Agentdevx Sdk mirajmahmudul Security	Assay Rul1an Security
Summary	Give your AI hands. Identity and credential vault gateway for autonomous agents. Ed25519 cryptographic identity (not OAuth), AES-256-GCM encrypted credential vault, OPA policy engine with full audit logging (captures allowed and denied actions), persistent per-agent memory, and web scraping tools. Self-bootstrapping — an agent can discover, register, and start calling tools with zero human setup. Register any API via OpenAPI spec.	Policy-as-code gate for MCP. A fail-closed proxy that denies risky tool calls before they run, produces offline-verifiable evidence bundles of what executed, and enforces IPv4/TCP egress in-kernel via eBPF/LSM and Landlock on Linux. Deterministic and offline-first.
