Feature & Specification Comparison

Specification	Argus alexar76 Security	Truecopy askalf Security
Summary	ARGUS-3 as a stdio MCP server (argus mcp → argusask, argusstatus). WARDEN vets third-party MCP servers before any tool runs (LUMEN-scored firewall, tool-def pinning, drift sentinel). Distinct from aimarket-oracle-gateway (oracle tools) and aimarket-plugins (hub packager). npm @alexar76/argus3 · live.	Supply-chain gate for agent skills and MCP servers — scans tool definitions for poisoned instructions, pins vetted servers by content hash in a committed lock, and verifies drift in CI; the bundled truecopy-mcp proxy exposes only pinned, unmodified tools from a live server.
