What it is

An MCP server over the Mem0 memory layer: it stores facts and retrieves them by semantic relevance, providing durable cross-session memory that survives beyond a single machine or conversation. It is the managed, personalization-oriented memory tier.

When to use it

When an agent should remember a user's preferences, project facts, or prior decisions across many sessions — the kind of long-term memory a local per-session store can't provide. The trigger is "remember this about me/the project."

How to install / invoke

Add the Mem0 MCP server to your MCP config with an API key. Write facts with the add-memory tool and recall with the search-memories tool.

Notes

One layer in a memory stack: pair a local entity graph (immediate persistence) with a managed semantic store (long-term recall). Be deliberate about what you persist — store durable facts, not transient chatter.

wikimem

Use to give an agent a queryable wiki knowledge base — ingest files, folders, and URLs into a linked vault, then search or ask it in natural language — when memory should be a navigable knowledge graph, not just a flat log.
