Memory

A knowledge-graph memory server — the agent stores entities, relations, observations and queries them across sessions.

Tier 1 sealed by curl

Memory is the official knowledge-graph store. Entities, relations, observations. It's how an MCP agent stops forgetting between sessions — and the schema is deliberately small so you can hand-edit the graph when the agent has gotten something wrong. If you've been faking memory with a JSON blob in a prompt, trade up.
