Preguntas frecuentes

¿Es seguro MAGNEMO?

Superó 1 de 1 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.

¿Qué claves o códigos necesita?

Debes completar: MAGNEMO_VAULT

¿Se ejecuta en mi computadora o en la nube?

Se ejecuta en tu computadora. Tu app de IA lo inicia cuando hace falta, y los datos no pasan por los servidores del creador (a menos que el propio servidor llame a un servicio en línea).

¿Sigue en mantenimiento?

El repo de GitHub cambió por última vez –, y la última versión (0.6.11) llegó al registro hace 8 días.

¿Qué apps pueden usarlo?

Las apps compatibles con MCP, como Claude Desktop, Claude Code, Cursor y VS Code. También necesitas Python (uv) en tu computadora.

The Memory MCP. Your AI remembers. You keep what matters.

MAGNEMO is Memory for your AI, kept on your computer in plain files. Your AI writes down what it learns as it works; nothing becomes Memory until you approve it, and every Memory shows who wrote it and who approved it.

Your agent writes one line down and keeps working. Say keep, and it is Memory.

Install in one paste

In three lines:

pip install MAGNEMO      # Python 3.11 or newer

magnemo init # makes the vault: a folder of plain files magnemo mount # writes .mcp.json, the file Claude Code reads, and the first line in CLAUDE.md

Or let your agent do it. Open Claude Code in any of your project folders, and paste this. (Its magnemo mount step writes .mcp.json, the file Claude Code reads, and a short block in CLAUDE.md that tells every new session where this project's Memory is. In Cursor, Windsurf or another client, use the block for your client under "Install in your client".)

Set up MAGNEMO in this project:
  1. Install it: pip install MAGNEMO. It needs Python 3.11 or newer. If pip can't find it, install uv (curl -LsSf https://astral.sh/uv/install.sh | sh) and then run: uv tool install MAGNEMO
  2. Initialize the vault: magnemo init
  3. Register the MCP server: run magnemo mount — it adds MAGNEMO to this project's MCP config and keeps any servers already there.
  4. Verify: run magnemo doctor and confirm everything passes.
  5. Then ask me to restart you, so MAGNEMO's tools load, and to say this when you are back: "Look around this folder, tell me what this project is for, and stage that as the first note." Your agent never waits on you. When you want something kept, say keep.

If anything fails, show me what went wrong and fix it if you can.

Plant the seed: one paste, and your agent grows a Memory.

After the restart, say it: Look around this folder, tell me what this project is for, and stage that as the first note. Your agent writes one line down and keeps working. Say keep, and it is Memory. Then ask what it remembers.

Works with

One server, the same in every client. Tested where it says so; the rest follow each client's own docs.

How it compares

Five questions, answered from each project's own docs (read Oct 12, 2026, checked again Oct 22; the pages are linked under the table).

MAGNEMOMem0ZepLettaBasic Memory
Where the memory livesPlain markdown files in a folder on your computerA hosted platform run by Mem0; open source: a local Qdrant store and a SQLite history fileZep: a managed cloud service, or in your own VPC. Graphiti, its open-source engine: a graph database you runMarkdown files in a git repository that belongs to the agent: hosted by Letta, or on your device in local modeMarkdown files on your disk with a local SQLite index; an optional cloud
Who approves a writeYou. An agent's write waits in staging until your yesAn LLM extracts facts from the messages and stores them; their docs describe no approval stepMessages are ingested into the graph as they arrive; their docs describe no approval stepThe agent updates its own memory; the background review "does not ask you for approval"The assistant writes notes directly; the cloud has suggested edits that can be accepted or rejected
Author and approver on every entryBoth, in each file's header (author, reviewed_by) and in an append-only ledgerUser, agent, app and run ids, timestamps, and a change history per memory; their docs name no approver fieldWhen a fact was true and when it stopped, traced to its source episode; their docs name no approver fieldEvery memory edit is a git commit; their docs do not say what the commit recordsTitle, type, tags and dates; author is a field you may add; their docs name no approver field
Network calls of its ownNone. No model call and no embedding call; git push to a backup, if you add oneOpenAI by default for the model and the embeddings; other providers are listed, Ollama among themZep is a cloud API. Graphiti defaults to OpenAI; local model servers are documentedLocal mode keeps state on your device; inference goes to the provider you choose, which can be a local oneRuns locally; the default embeddings run on your machine with no API key
What you can take backA no is kept with its reason; a replaced note is archived with a forward link; nothing deletes; the files are yours to editDelete, update, and a history per memory; export is on the hosted platformDelete nodes, edges and episodes; a replaced fact is invalidated, not deletedThe git history of every memory edit; the files can be read and editedPlain files you edit and can track with git; a delete tool; the cloud keeps every saved version

Where each of them is ahead. Mem0 extracts memories for you, searches them by meaning, and has Python and JavaScript SDKs, a REST API and a hosted platform. Zep keeps a knowledge graph that knows when each fact was true, as a managed service with SDKs in three languages. Letta is a whole agent platform, with an SDK, a CLI and background agents that tend the memory. Basic Memory searches by keyword and by meaning with embeddings that run on your machine, links notes into a graph, and syncs through its cloud. MAGNEMO has none of that: its search is keyword search (KNOWN_LIMITS.md), there is no graph and no hosted service. What it has is the approval and the record.

Their pages: Mem0 overview, platform and open source, add, history, quickstart, delete, export · Zep concepts, facts, security, deleting data, Graphiti · Letta MemFS, memory settings, local mode · Basic Memory README, what it is, tools, note format, semantic search, suggestions, file history. A cell that is wrong or out of date: open an issue and it is fixed.

Listed on the official MCP registry (ai.magnemo/magnemo) · PyPI · mcpservers.org · Glama · awesome-mcp-servers. Tested on every push, on Python 3.9, 3.11 and 3.12: 370 tests, as of Oct 28, 2026 (the runs).

What's new

  • 0.6.11 · Oct 28, 2026 · magnemo mount writes the first line in CLAUDE.md, so every new session knows where this project's Memory is. pending reads a note nobody has kept yet.
  • 0.6.10 · Oct 26, 2026 · Your agent never stops to ask. Say keep in the chat, and the record says how the yes was given.
  • 0.6.9 · Oct 22, 2026 · A seat's report files itself as a receipt and asks nothing; a yes is for Memory. Sentinel reads a seat's quote as a quote.

Every release: CHANGELOG.md.

For builders. MAGNEMO is an MCP server with four verbs — retrieve, stage, bootpack, handoff — plus keep, drop, pending, and a CLI for your side: review, promote, reject. It runs on your machine, in plain markdown files you own. The package imports no network module (magnemo doctor scans for one on every run); the only traffic is git push to a backup destination, if you add one. Every promotion is recorded with who wrote the entry, the name given for the yes, when, and through which gate. Trust is computed from that record, never asserted. It mounts beside any memory you already run (a folder of notes, Obsidian, a RAG stack). Python 3.11+, zero dependencies, Apache-2.0.

Fresh vault? THE CHARTER section will say it isn't promoted yet — that is the governance speaking: MAGNEMO never fabricates canon. Stage a charter, review it, promote it, and every boot thereafter serves it back verbatim. (magnemo not found after install? pip's script folder isn't on PATH — python3 -m magnemo always works.)

Open beta — read [KNOWN_LIMITS.md](KNOWN_LIMITS.md) before trusting it with anything you can't lose. Honest caveats, no fine print.

Install in your client

One server, said ten ways. Every block below is the same thing: uvx magnemo-mcp with MAGNEMO_VAULT pointing at the folder your Memory lives in (make one with magnemo init ./vault). Tested on this Mac where it says so; the rest is from each client's own docs and marked untested — corrections welcome, open an issue.

Claude Code — tested: a Claude Code session mounts the server, lists the seven tools and calls them; a yes in the chat keeps a note, and pending reads a body (last run Oct 28, 2026: Claude Code 2.1.309, the 0.6.11 server).
