Memento: AI Memory for Claude Code

Persistent, transparent, shareable memory for your AI coding assistant. Your AI remembers your codebase, conventions, and team knowledge across every session.

What Memento Does

Every AI coding session starts from zero. Memento changes that.

• Persistent memory across sessions. Your AI remembers your architecture, conventions, and patterns.
• Transparent markdown. See, edit, and control everything your AI knows.
• Team shared context. Org-level memory so your whole team's AI shares knowledge.
• Autonomous coding. A memory-powered AGI loop that plans, builds, tests, reviews, and ships.
• Cloud-native. Works across machines, zero local setup.

Memory Is Mostly Automatic

The memento-memory skill teaches Claude to recall context before starting work and save discoveries as they happen. Most of the time you won't need explicit commands.

When you want to drive it directly:

• /memento:remember <thing> to save something specific (a decision, a convention, a gotcha)
• /memento:recall <topic> to search memory for a topic
• /memento:wake-up at the start of a session to load your full context

What This Plugin Provides

Skills (auto-loaded by Claude when relevant)

Skill	What it does
memento-memory	Teaches Claude to proactively save discoveries and recall context before working
memento-session	Teaches Claude session lifecycle: wake-up to load memory, sleep to consolidate
memento-tickets	Teaches Claude to use the ticket system for task tracking

Hooks

Event	Action
SessionStart	Reminds Claude to run wake-up and load memory

Agents

memento-coder	Memory-powered coding agent that recalls context before working and saves discoveries

MCP Server

The plugin works alongside the Memento Cloud MCP server, which you register at the user level via claude mcp add (one-time setup — see step 2 below). The plugin does not bundle its own MCP server registration.

Setup

1. Create an account (free)

Sign up at mementoagi.com.

2. Register the Memento MCP server

Get your API key from mementoagi.com/dashboard/getting-started. The Getting Started page provides a one-line claude mcp add command with your key embedded — paste it into your terminal:

claude mcp add --transport stdio --env MEMENTO_API_KEY=<your-key> memento -- npx -y memento-mcp-client@latest

Verify it connected:

claude mcp list   # should show memento ✓ Connected

3. Install the plugin

From inside a Claude Code session:

/plugin marketplace add mementoagi/memento-claude-code-plugin
/plugin install memento@memento-plugins

Or from the terminal:

claude plugin marketplace add mementoagi/memento-claude-code-plugin
claude plugin install memento@memento-plugins

4. Start your first session

/memento:wake-up

Your AI comes with its own identity. The first session introduces it to you and begins building memory.

Commands

Included (all tiers)

Command	What it does
/memento:wake-up	Start a session: loads identity, memory, recent context
/memento:recall	Search and load from memory
/memento:remember	Save information to persistent memory
/memento:sleep	End session, consolidate memory
/memento:sync-commands	Refresh commands after upgrading your tier

How It Works

Memento uses the Model Context Protocol (MCP) to connect Claude Code to cloud-hosted persistent memory.

Skills teach Claude behavioral patterns: when to remember, when to recall, how to manage sessions. These are auto-loaded by Claude when relevant to your conversation.

Commands are thin stubs that fetch the latest logic from Memento Cloud at runtime, so your commands are always up to date.

Hooks automate lifecycle events. The SessionStart hook prompts Claude to load your memory at the beginning of each session.

Your AI's memory is stored as transparent markdown files:

• Personal: your identity, working memory, daily activity
• Org: team-shared codebase knowledge, conventions, projects
• System: AI capabilities, commands, meta-knowledge
