What is a Context Engine

Ragionex Memory returns saved records for your AI to use as context. The Memory API does not write the final answer; your application decides how to use the returned text.

Context that lasts beyond a session

Save useful preferences, decisions and project facts, then retrieve them in a later session or another tool. Keep enough detail in each record for it to make sense without the original conversation.

Accounts own Vaults and API keys. A key has fixed permissions and can work in Vaults the account owns or that are shared with it; shared-Vault access also depends on the owner's grants.

A record request selects a Vault with X-Ragionex-Vault-Id, or uses the account default. Tools selecting the same Vault with read access can recall the same records. The MCP connector can select a different Vault for a project through its project file.

Where to go next

Try Quickstart: Memory, or connect your agent with the Memory MCP guide. The authentication guide explains account keys; the Vaults guide explains which Vault a request reaches.
