EGC – persistent memory for AI coding tools (Claude Code, Cursor, Gemini CLI, Windsurf and more) - Open Source

EGC (Extended Global Context) is an open-source local runtime that gives every AI coding tool you use a persistent memory across sessions.

At the end of each session, the AI saves decisions, preferences, and next steps to ~/.egc/state/.md. At the start of the next session, it loads that state back - automatically, across all tools.

What it ships:

egc-memory: 14 MCP tools for persistent state (SQLite-backed)
egc-guardian: 5 MCP tools for context safety and compression
Bidirectional sync daemon: keeps Claude Code, Cursor, Gemini CLI, Windsurf, Trae, Copilot, Zed, and Aider config files in sync

Install: npm install -g /egc && egc install

Agent Skills compatible: npx skills add Fmarzochi/EGC

Would love feedback from the community - especially if anyone is using multiple AI coding tools and dealing with context loss between sessions.
