Score: 7.0/10 (Innovation: 6, Technical: 7, Documentation: 8, Utility: 7)

Aquifer is a self-hosted MCP traffic framework that queues and rate-limits HTTP requests from distributed agents, protecting backends from bursts and respecting upstream rate limits. It is interesting because it combines durable SQLite-backed queuing, pluggable adapters (MCP and HTTP), and a trustless webhook protocol (L8), addressing a real pain point in agent coordination and API rate management.

Target audience: backend devs, devops, ai engineers
