n8n-nodes-studiomeyer-memory

Long-term AI memory for n8n agents. Drop-in memory layer with knowledge graph, semantic search, entity tracking, and session continuity. Powered by StudioMeyer Memory.

What this is

n8n's built-in memory options (Postgres, Redis, Motorhead) handle short-term conversation history but stop there. StudioMeyer Memory is a long-term layer:

• Semantic search across past decisions, learnings, and sessions
• Knowledge graph with typed entities (people, projects, services) and relations
• Bi-temporal tracking so you can query "what did we know about X on date Y?"
• Confidence + decay so old contradicted facts fade automatically
• Multi-tenant on Supabase EU - DSGVO-compliant by default

This community node connects your n8n workflows to the StudioMeyer Memory MCP server (hosted SaaS at memory.studiomeyer.io) and exposes the most useful operations as a clean Resource/Operation tree. The custom Server URL field in the credential lets enterprise customers point at a managed-on-your-infra deployment after a commercial agreement, the public self-host bundle is a planned v0.2 release.

Why this matters

A voice agent that remembers callers across sessions. A customer support bot that knows the customer's preferences from three months ago. A personal assistant that builds a profile of you over years, not minutes. n8n is the perfect glue layer - but it lacks a real long-term memory primitive. This node fills that gap.

Install

In your n8n instance: Settings → Community Nodes → Install

Enter the package name:

n8n-nodes-studiomeyer-memory

Or via npm if you self-host n8n:

npm install n8n-nodes-studiomeyer-memory

Quick start

1. Get an API key. Sign in at studiomeyer.io/portal/login (Google, GitHub, Discord or email magic link). Inside the portal, click "Free Memory testen" - you get an API key with 200 free credits, no credit card. Copy the key from your dashboard at studiomeyer.io/portal/api.
2. Add the credential in n8n. Settings → Credentials → New → "StudioMeyer Memory API". Paste your key.
3. Drop the StudioMeyer Memory node into a workflow. Pick a Resource (Memory / Entity / Session / Insight) and an Operation.

Resources & Operations

Memory

The four core read/write operations.

| Operation | Maps to | Use case | |---|---|---| | Search | nex_search | Semantic + keyword search across all memory types with temporal decay | | Recall | nex_recall | Faster lightweight recall (full-text only) | | Learn | nex_learn | Persist a fact, pattern, mistake, or workflow note | | Decide | nex_decide | Record a decision with rationale and confidence |

Entity

Knowledge graph operations.

| Operation | Maps to | Use case | |---|---|---| | Create | nex_entity_create | Add a person, project, service, or concept | | Observe | nex_entity_observe | Append observations to an existing entity | | Search | nex_entity_search | Fuzzy search across names + observations | | Relate | nex_entity_relate | Connect entities (uses, depends_on, competes_with, custom) | | Open | nex_entity_open | Fetch one entity with all observations + relations |

Session

Manage long-running agent sessions.

| Operation | Maps to | Use case | |---|---|---| | Start | nex_session_start | Open a session, load context, get a session ID | | End | nex_session_end | Close a session and persist a summary | | Recall Timeline | nex_recall_timeline | Chronological view of recent activity |

Insight

Higher-level synthesis.

| Operation | Maps to | Use case | |---|---|---| | Synthesize | nex_synthesize | Cluster recent learnings into an insight | | Reflect | nex_reflect | Surface emerging patterns + contradictions | | Proactive Briefing | nex_proactive | Status briefing - stale learnings, open decisions, knowledge gaps |

Authentication

Two modes, same endpoint:

• API Key (default, recommended). Paste a key from your portal at studiomeyer.io/portal/api. First-time users sign in once at /portal/login, click "Free Memory testen", and the API key appears in the dashboard. 200 credits, no card.
• OAuth 2.1 Access Token. Pre-issued token from a PKCE flow against memory.studiomeyer.io/authorize + /token. The OAuth discovery doc is at memory.studiomeyer.io/.well-known/oauth-authorization-server. The fully integrated browser flow (n8n OAuth2 credential type) ships in v0.2.

Both modes target https://memory.studiomeyer.io/mcp. The custom Server URL field is intended for managed-on-your-infra enterprise deployments (server source under commercial source-grant); a public self-host bundle is a planned v0.2 release.

Recipes

Voice agent that remembers callers

Voice Webhook (Vapi/Retell)
  → Memory: Search (query: caller_phone, types: ["entity", "learning"])
  → AI Agent (with caller context in system prompt)
  → Memory: Learn (content: "Caller X asked about Y, agent answered Z")

Customer support with full ticket history

WhatsApp Trigger
  → Entity: Search (query: customer_email, entityType: customer)
  → Entity: Open (entityRef: matched_id)
  → Anthropic Claude (with full customer context)
  → Memory: Learn (tag the ticket outcome)

Personal assistant with long-term memory

Telegram Trigger
  → Session: Start (project: telegram-bot, agentId: user_id)
  → Memory: Search (query: telegram_message, recencyWeight: 0.5)
  → AI Agent
  → Memory: Learn (whatever the user just told you)

Pricing

Free tier is 200 free credits activated by one click inside the portal at studiomeyer.io/portal/login (no card). Each operation (search, learn, entity-create, etc.) consumes one credit. Enough to evaluate the node and run a single bot in development. Pro is €29/month and lifts the limit to a generous monthly cap. Team is €49/month with multi-agent isolation. See studiomeyer.io/services/memory for the latest pricing and the per-tier cap.

Hosting model. This community node and its tests are MIT-licensed (use the node anywhere, commercial OK). The Memory server is currently hosted SaaS only (EU Frankfurt, Hetzner) - it is not self-hostable today. The server source lives in a private repo. If self-hosting is a hard requirement for your deployment (sovereignty, air-gap, customer contract), contact [email protected] about a commercial source-grant or managed-on-your-infra option.

Roadmap

• v0.1 (current, latest published v0.1.2): Memory / Entity / Session / Insight resources, API Key auth, OAuth 2.1 access token (paste a pre-issued token from a PKCE flow). v0.1.1 + v0.1.2 are documentation hot-fixes (corrected portal URL, free-tier credit count, signup flow).
• v0.2: AI-Agent Memory Sub-Node (drops directly into the n8n AI Agent's Memory slot, replacing Postgres / Redis / Motorhead). Dedicated n8n OAuth2 credential type with full browser-based PKCE flow. Bundle @modelcontextprotocol/sdk into the published artifact to satisfy the n8n Verified Community Nodes "Zero Runtime Dependencies" requirement (deadline was 1 May 2026 - the v0.1.x line is shipped as an Unverified community node; Verified-status submission ships with v0.2 once SDK bundling lands and is smoke-tested).
• v0.3: Streaming support for long search results, batch operations
• v0.4: Workflow templates published to n8n.io marketplace

Development

git clone https://github.com/studiomeyer-io/n8n-nodes-studiomeyer-memory

npm install
npm run build
npm test

To test locally in your n8n instance:

npm link
