mainframe-mcp
sushiHex/mainframe-mcp
100% local knowledge and persistent memory for coding agents. GPU-accelerated hybrid search with source citations and a low VRAM footprint, powered by one shared MCP daemon.
YantrikDB
yantrikos/yantrikdb-server
Cognitive memory database for AI agents — consolidates duplicates, detects contradictions, fades stale memories via temporal decay. Rust, Apache-2.0, ships as library / MCP server / HTTP cluster.
CodeAlive
