mcp_knowledge 0.3.0

Unified knowledge management system integrating facts, skills, profiles, and operations with facades, bridges, and event-driven architecture for the MCP ecosystem.

// The knowledge system over an in-memory fact graph: text ingested through
// the ingest facade, facts read through the fact facade. The example prints
// what it did.
// ignore_for_file: avoid_print
