AAAA-Nexus MCP

aaaa-nexus/aaaa-nexus-mcp

The source material is minimal, but this appears to be a monetized API gateway for AI safety tooling with formal verification backing. You get 75+ endpoints accessible through pay-per-call USDC payments over the x402 protocol, which removes the usual signup friction. The formal verification angle suggests mathematically proven safety properties rather than heuristic checks. Reach for this when you need AI safety primitives with cryptographic payment rails and want to avoid maintaining API keys or subscriptions. The Atomadic ecosystem references (Murmuration, Fuse, Nexus) hint at a broader lattice of interconnected services, though specifics on individual endpoints aren't detailed in the available documentation.
