n8n

n8n’s MCP node can connect directly to HyperMemory, giving your workflows access to all 12 memory tools.

Setup

1. Add an MCP Client node to your workflow.
2. Set Server URL to:

https://api.hypermemory.io/mcp

3. Authentication: configure either:

   • OAuth2 credentials (recommended) — n8n handles the token flow
   • Header Auth — set Authorization to Bearer hm_YOUR_KEY_HERE

4. Select the tool to call (e.g. hm_store, hm_recall).

Example: store a memory from a webhook

1. Webhook node receives incoming data
2. MCP Client node calls hm_store with:
   • key: extracted from webhook payload
   • description: summary of the event
   • data: structured metadata

Example: recall before responding

1. MCP Client calls hm_recall with a search query
2. IF node checks whether results were returned
3. Branch: use recalled context or proceed without

Example: ingest a document

1. HTTP Request node fetches document content
2. MCP Client calls hm_ingest with the full text and a context label
3. The server decomposes the text into graph entities in one LLM pass

Available tools

All 12 hm_* tools are available through the MCP node. See API Reference for parameters and response shapes.
