Introduction

HyperMemory is a long-term memory service for AI agents, built on hypergraph technology and exposed as an MCP server.

What makes HyperMemory different

• Not a vector database — Memories have explicit relationships, not just embeddings
• Not a chat history store — A structured knowledge graph your agent navigates
• Hypergraph-native — Multi-way relationships that capture complex contexts

Who is HyperMemory for

• Developers building AI agents that need to remember across sessions
• Teams running multi-agent systems with shared knowledge needs
• Anyone using MCP-compatible tools (Claude, OpenClaw, CrewAI, OpenAI)

Key capabilities

Store memories

Save nodes with metadata and relationships

Recall by language

Query memories using natural language

Traverse relationships

Navigate multi-way connections (hyperedges)

Share knowledge

Export/import subgraphs between agents

How it works

HyperMemory runs as a remote MCP server at api.hypermemory.io. Your agent connects over HTTP/SSE, authenticates with an API key, and gets access to memory tools.

Memories are stored as nodes in a hypergraph. Relationships between memories are stored as edges and hyperedges. Your agent reads and writes to this graph using natural MCP tool calls.
