⚡ The open-source persistent cognitive memory layer for AI coding agents. Stop your Cursor, Claude & Copilot from having amnesia.
An open-source, self-hosted persistent cognitive memory layer for AI coding agents (Cursor, Claude, VS Code). Persists architecture decisions, schemas, and preferences across sessions via the Model Context Protocol (MCP).

Problem: Session Amnesia & Token Overhead
Modern coding assistants (Cursor, Claude Code, Copilot, Antigravity) initialize each chat thread without cross-session memory. While developers frequently mitigate this using project documentation (AGENTS.md, prompt templates, or manual file references), this workflow presents two major bottlenecks:
1. Context Window & Token Inefficiency: Injecting massive architecture documents or having agents repeatedly read entire repository directories consumes thousands of context tokens on every single query. 2. Loss of Incremental Decisions: Ephemeral decisions—such as chosen dependency versions, schema adjustments, or bug fix rationale made in prior sessions—are lost when a session resets, forcing developers to repeatedly re-explain core constraints. ---
Friday runs as an open-source, self-hosted Model Context Protocol (MCP) server. Instead of dumping entire documentation files into prompt context, Friday exposes 4 targeted tools (addmemory, addfact, memorysearch, getcontext) backed by a multi-tier storage engine:
