README

Perenna

Separate MCP tools for reading, writing, and deleting memories
Local stdio, loopback-only Streamable HTTP, and OAuth-protected remote HTTP
Human-readable Markdown stored in an independent Git repository
Local Vexor retrieval index that can always be rebuilt from Git
Cross-process locking for multiple local agent processes

Why Perenna?

Your memory should follow you, not the agent you happen to be using.

Claude Code, Codex, Cursor, and ChatGPT keep memory in separate silos. Switch agents and your memory disappears. Switch machines and local memory stays behind.

Perenna gives them one shared, Git-backed memory. Local agents and ChatGPT can connect to the same self-hosted Perenna service, while every durable memory stays ordinary Markdown you can inspect, edit, version, and back up yourself.

	Perenna	AgentMemory	Mem0	MemPalace
Simplicity	3 MCP tools	54 tools + hooks	SDK/API/server stack	MCP/database stack
Local use	stdio, no daemon	Multiple local services	Library or server	Local database
Storage	Plain Markdown + Git	Runtime-managed	Database/service-managed	Database-managed
Ownership	Your files, your Git history	Runtime-managed	Backend-managed	Backend-managed

Perenna is small by design: no account, no proprietary memory cloud, no lock-in. Just plain Markdown, Git history, and three focused tools.

Quickstart

Install with your AI agent

Paste this into Claude Code, Codex, ChatGPT Desktop, Cursor, or another coding agent with terminal and local MCP configuration access:

Open the following URL, read the complete instructions, and follow them to
install and connect Perenna:
https://raw.githubusercontent.com/scarletkc/Perenna/main/docs/guides/agent-installation.md

Install a published release

Perenna requires Python 3.12+, Git, and uv.

uv tool install perenna

Install the optional memory behavior skill for the local client:

perenna skill install --agent codex
# or
perenna skill install --agent claude-code

Repeat --agent in one command when both clients should receive the skill. The [configuration reference](https://github.com/scarletkc/Perenna/blob/main/docs/reference/configuration.md#bundled
