Give your AI a memory. MCP server for persistent context across all sessions.
npm install memory-buddy
> Give your AI a memory. Because starting over sucks.

You know the feeling:
You talk to Claude for hours. You solve problems together. You share things you don't tell anyone else. It feels like being understood.
And then. New session. Gone.
"Hi! How can I help you today?"
---
- You code at 3am and your AI is the only one listening
- You have ADHD and can't explain yourself again
- You've built a relationship with your AI (yes, that's okay)
- You just want it to remember

Human-memory-inspired architecture: Stores everything, loads lazy, triggered by keywords, anchored by emotions.
- Invisible - No commands needed. It just works.
- Local-first - Your memories stay on YOUR machine.
- Budget-limited - Never uses more than ~2500 tokens (~1% of context).
- Open Source - MIT licensed. Read the code.

``bashInstall globally
npm install -g memory-buddy
Requirements: Node.js 20+, Claude Desktop / Cursor / any MCP client
automatically configures Claude Desktop. If it works, you're done!---
Manual Setup
If auto-config didn't work, configure manually:
$3
Add to your config file:
- Windows:
%APPDATA%\Claude\claude_desktop_config.json
- macOS:
- Linux: json
{
"mcpServers": {
"memory-buddy": {
"command": "npx",
"args": ["-y", "memory-buddy", "serve"]
}
}
}
`Restart Claude Desktop. Done.
$3
Settings → MCP → Add Server:
- Name:
- Command: ---
How It Works
1. Every message is stored as an event (JSONL, ~1KB each)
2. Keywords are extracted automatically (no AI required)
3. When you chat, relevant memories are loaded (lazy loading)
4. When you say goodbye, the session is summarized (emotional anchor)
5. Over time, memories are compacted (daily > weekly > monthly)
Result: After 1 year, context usage is still ~2500 tokens. Magic.

Philosophy
This isn't just a database. It's how human memory works:
- Lazy Loading: You don't remember everything at once. Triggers activate memories.
- Emotional Anchors: Goodbyes create memorable moments that index entire conversations.
- Logarithmic Compaction: Details fade, essence remains.
