Knowledge Graph Memory

# Knowledge Graph Memory

Store and retrieve entities and relations as a local knowledge graph. Writes to disk in the server's own directory only.

- **Documentation:** https://github.com/modelcontextprotocol/servers/tree/main/src/memory
- **Transport:** stdio (local process)
- **Command:** `npx -y @modelcontextprotocol/server-memory`

## Credentials and configuration

None required.

## Tools (5)

- `create_entities` — Store entities and their observations.
- `create_relations` — Store relations between stored entities.
- `delete_entities` — Delete entities and their relations.
