Memory MCP
Local · stdioA reference persistent-memory server: entities, relations and observations in a local knowledge graph. The agent remembers facts across sessions and retrieves them on demand.
Why this server
- A plain JSONL file instead of a database — easy to inspect and put in git
- MEMORY_FILE_PATH switches memory between projects with a single env var
- Observations store one fact each — delete a single fact without touching the rest
- search_nodes searches by name, type and observation content in one call
Usage examples
Prompt: Remember that the client prefers to receive reports on Fridays
Result: The agent created an entity via create_entities and attached a fact with add_observations — next time it's found via search_nodes.
Prompt: What do we know about project X from earlier conversations?
Result: The agent called search_nodes for the project name and returned the related entities and observations from the graph.
Local server
This MCP runs locally on the user's machine (stdio), so availability isn't tracked — rely on reviews and the rating instead.
