Every agent.
Every machine.
One memory.

mddb keeps what your AI agents learn — and how they're set up — in sync: agent memory, CLAUDE.md, skills, MCP servers, subagents. On all your machines and across harnesses. Config depreciates as harnesses get smarter; memory compounds — and vendors won't export it for you. mddb does.

mddb, the sync octopus
mddb orbit: agent memory sync inside a live session

the problem

Your agents are drifting apart

// divergence

Claude Code and Codex each keep their own instructions. Your desktop and laptop each keep their own skills. Four environments, four different brains.

// reinstall pain

New machine or fresh install means hours of copying dotfiles, re-adding MCP servers, hunting for that one skill you wrote last month.

// no undo

An agent rewrites its own config, something breaks, and there is no history, no diff, no rollback. You reconstruct it from memory.

// config debris

Rules in CLAUDE.md, skills in dotfiles, MCP servers in JSON, env vars in your head. One environment, scattered across files, folders and formats.

// dead MCPs

An MCP server sits in the config but stopped working weeks ago. Nothing checks it, nobody notices until it fails mid-demo.

// amnesia

Claude Code remembers your conventions and preferences. Codex starts from zero. Every new harness is an amnesiac — it knows nothing your other agents learned.

what mddb does

Not a file sync. A canonical model.

mddb doesn't copy files between machines. It parses your setup into meaning (memories, rules, skills, MCP servers, subagents), versions every change, and compiles it back into each harness's native format. Raw facts travel; vector indexes and binary state stay local and get rebuilt by the harness.

Memory that moves with you

Agent memory is the most locked-in asset you own — no vendor will export it. mddb syncs raw memory: markdown files and append-only logs, merged without conflicts, rebuilt into whatever each harness keeps locally.

Cross-harness translation

One rule becomes a managed section in CLAUDE.md for Claude Code, AGENTS.md for Codex, QWEN.md for Qwen Code. Edit any side and it syncs back.

History, snapshots, rollback

Every change is an immutable event. See who changed what, from which machine, and roll any of it back.

Secrets never leave

API keys and tokens are never uploaded, only references and env-var names. Built-in secret scanning blocks accidents before they sync.
