Local-first, formally verified memory for AI agents: consult/learn/related/list over MCP.
If you already use Mnema, the mnema mcp server is the piece that lets your assistant work with it directly. Local-first, formally verified memory for AI agents: consult/learn/related/list over MCP.
Your agents rent their intelligence from a lab; their memory should be yours. Mnema is a single, durable store of what your agents have learned — consult it before you act, learn a durable fact, walk the related graph, list what's recent. Data lives in ~/.mnema on your machine and nothing leaves it unless you point it somewhere.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Local — first.** An open, append-only segment format in ~/.mnema. No cloud,Platform — AssetEnv — DefaultMNEMA_DATA_DIR — ~/.mnemaMNEMA_URL — http://127.0.0.1:7077MNEMA_TOKEN — —Configuration is passed through the environment: MNEMA_URL, MNEMA_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Among the knowledge and memory options, the useful question is rarely "what can it do" but "what does it cost you to run" — permissions, credentials, and how much of your context its toolset consumes. Mnema's toolset — Local, Platform, Env and 3 more — is a fair guide to whether it matches your workflow. It is maintained by ai.zimac; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
