MCP tool

store_facts

Store up to 50 facts in one call — the same fields as store_fact per item.

The store_facts tool is provided by ctxstore — memory that follows you across models. Install that server in your AI client and the assistant can call it directly.

Servers exposing store_facts

Tool lists are read from the live servers (or, for packaged servers, from their documentation) each morning, so this reflects what they exposed at the last refresh. Search all tools.
