Piia Engram Overview

Patdolitse/piia-engram MCP server gives MCP-compatible AI tools access to a shared, local user identity and knowledge store. It saves preferences, lessons, decisions, playbooks, project snapshots, and session context as local JSON or Markdown, with optional field-level AES-256-GCM encryption. Startup, retrieval, writeback, governance, and session-management tools let agents reuse approved context across tools while keeping files under the user's control. Reach for it when multiple coding agents need consistent preferences and recoverable project context without a cloud memory service.

Primary Use Cases for Piia Engram:

Share coding preferences across Claude Code, Cursor, and Codex
Store reusable lessons from completed engineering work
Record architectural decisions with their reasoning
Recover project and session context after a restart
