~/Library/Application Support/Claude/claude_desktop_config.json · Windows: %APPDATA%\Claude\claude_desktop_config.json

{
  "mcpServers": {
    "marm-systems": {
      "command": "uvx",
      "args": [
        "MARM-Systems"
      ],

Ouvrez Claude Desktop → Settings → Developer → Edit Config. Redémarrez après avoir enregistré.

~/.cursor/mcp.json · .cursor/mcp.json

{
  "mcpServers": {

Cursor utilise le même schéma mcpServers que Claude Desktop. La config projet l'emporte sur la globale.

Cliquez sur l'icône MCP Servers dans la barre latérale Cline, puis "Edit Configuration".

      "_inferred": true
    }
  }
}

Même format que Claude Desktop. Redémarrez Windsurf pour appliquer.

~/.continue/config.json

Continue utilise un tableau d'objets serveur plutôt qu'une map.

Cas d'usage

Usages concrets : MARM-Systems

Build persistent memory across sessions on a long project

👤 Anyone working a multi-week effort with an AI ⏱ ~15 min beginner

Quand l'utiliser : You keep re-explaining the same project background every session.

Prérequis

MARM-Systems installed and running — docker pull lyellr88/marm-mcp-server && docker run -d -p 8001:8001 lyellr88/marm-mcp-server

Déroulement

Start a session tagged to the project

marm_start with project tag 'dataplatform-migration'. Log that we're migrating from Redshift to Snowflake, deadline end of Q2.✓ Copié

→ Session started; initial entry saved
Drop context as you work

marm_contextual_log: 'Decided to use Fivetran for CDC replication, evaluated Airbyte but config overhead too high.'✓ Copié

→ Auto-classified and stored
Next session, recall

marm_smart_recall 'what did we decide about CDC tooling?'✓ Copié

→ Relevant past decision surfaces

Résultat : Session N+1 starts with all of session 1-N context accessible by query, not re-type.

Pièges

Dumping every chat into memory clogs recall — Use marm_contextual_log for decisions and milestones, not every exchange
Vector search misses on jargon — Tag entries explicitly with project names for keyword fallback

Combiner avec : drift

Share memory across a team using multiple AI assistants

👤 Teams where different members use Claude / Qwen / Gemini ⏱ ~45 min advanced

Quand l'utiliser : Knowledge trapped in one person's AI shouldn't be.

Déroulement

Run MARM as a shared HTTP server

Deploy MARM-Systems on a team server; each teammate points their MCP client at http://marm.team.internal:8001/mcp.✓ Copié

→ All clients connect
Log shared context

marm_contextual_log: 'Database backup runbook is at /runbooks/db-backup.md; last updated 2026-04-10.'✓ Copié

→ Everyone can recall it
Recall from any client

From a teammate's Qwen session: marm_smart_recall 'how do I restore the DB'?✓ Copié

→ Same answer surfaces

Résultat : Cross-AI shared institutional memory.

Pièges

Shared memory needs real OAuth — Don't rely on the dev hardcoded credentials — wire to your IdP before prod use
Sensitive data leaks into shared recall — Use project tags and scope queries by tag

Use notebooks as AI-queryable scratchpads

👤 Learners, researchers ⏱ ~5 min beginner

Quand l'utiliser : You want a topic-scoped note area the AI can search later.

Déroulement

Create a notebook

marm_notebook_add name='rust-ownership' with entry: 'Move vs borrow: move transfers ownership, borrow lets you peek.'✓ Copié

→ Notebook created
Add as you learn

marm_notebook_add 'rust-ownership': 'Mutable borrow is exclusive; only one at a time.'✓ Copié

→ Entry appended
Recall later

marm_notebook_show 'rust-ownership'✓ Copié

→ Full notebook

Résultat : A queryable learning journal.

Combinaisons

Associez-le à d'autres MCPs pour un effet X10

marm-systems + drift

drift remembers code conventions; MARM remembers project decisions

Recall drift conventions AND MARM decisions for project 'dataplatform-migration' and summarize where they interact.✓ Copié

marm-systems + claude-code-organizer

Move short-lived memories out of CC into MARM for long-term recall

Organizer listed my 12 biggest memories — move the 5 project-specific ones into MARM notebooks.✓ Copié

Outils

Ce que ce MCP expose

Outil	Entrées	Quand appeler	Coût
marm_start	project?, tags?	Start of any working session	free (local)
marm_refresh	session_id?	Reload context mid-session	free
marm_smart_recall	query: str, top_k?: int	Semantic search past entries	free (local embeddings)
marm_contextual_log	text: str, tags?: str[]	Persist a decision/milestone/fact	free
marm_log_session	session_id	Review a past session	free
marm_notebook_add	name: str, entry: str	Topic-scoped notes	free
marm_notebook_use	name: str	Pin a topic for the session	free
marm_notebook_show	name: str	Read a notebook	free
marm_summary	scope: session\|notebook\|tag, id	Condense long history	free (local)
marm_context_bridge	from_session, to_session	Cross-project reasoning	free

Coût et limites

Coût d'exécution

Quota d'API: None — local-only
Tokens par appel: Recall responses 500-2000 tokens typically
Monétaire: Free, open source
Astuce: Rotate or archive old sessions periodically — SQLite handles scale but recall quality degrades with noise.

Sécurité

Permissions, secrets, portée

Stockage des identifiants : Local SQLite; for shared HTTP mode use env-based OAuth secrets

Sortie de données : None by default (local storage); if you run shared, only within your network

Ne jamais accorder : Exposing port 8001 to the public internet without an auth layer

Dev mode ships hardcoded OAuth credentials — change before any shared deployment.
Memory can accumulate sensitive data; back up and encrypt the SQLite file.

Dépannage

Erreurs courantes et correctifs

Cannot connect to localhost:8001

Container not running. docker ps to check; docker start marm-mcp-server.

Vérifier : curl http://localhost:8001/docs

Embeddings model download fails

First run downloads the model; needs outbound net. After that, offline works.

Vérifier : Check docker logs for HuggingFace download

Recall returns unrelated entries

Too few entries for good embeddings; add more, or pre-filter by tag.

Vérifier : marm_smart_recall with tag filter

Alternatives

MARM-Systems vs autres

Alternative	Quand l'utiliser	Compromis
drift	You want code-specific memory (conventions, decisions)	Code-focused; less general
Letta (MemGPT)	You want a research-grade memory agent, not just a server	Heavier to run; opinionated architecture
CC native memories	Claude Code only; no cross-client need	No semantic search; bloats context
