Setting up AI memory: plan one capture-and-recall path
Contents
Set up shared AI context
Start with one small pilot
Start with one useful record and one client. Decide what is saved, who may read it and how you will know that the next session retrieved the intended record.
Decide what continuity you actually need
“Give my AI a brain” can mean loading project instructions, resuming an unfinished task or retrieving shared decisions across tools. Those needs can use different storage and loading mechanisms.
This is a setup-planning guide, not a tested installation tutorial. It does not promise a free service, a ten-minute setup or automatic capture across every client. For a specific documented client exercise, use the Claude Code memory guide.
Choose the smallest suitable home
A reviewed project file may be enough for stable instructions. An existing decision document may be enough for a source the agent can retrieve. A separate service becomes relevant when you need a supported access path or scope that those existing systems cannot provide.
LangChain’s memory overview distinguishes persisted thread state from information available across conversations. That is a useful design distinction; it does not imply that everything disappears when a conversation ends. Memory overview
Prepare a record worth retrieving
Use a harmless fictional decision before connecting real company material. The example below records both a decision and its boundary; it does not save an entire conversation.
| Field | Value |
|---|---|
| Project | Workshop handbook |
| Decision | Keep the printed handbook to eight pages. |
| Reason | It must fit the existing folded handout format. |
| Status | Approved for the pilot workshop only. |
| Unresolved | Whether later workshops will use the same format. |
| Source | Test decision note D14, created for this exercise. |
Define capture before asking an agent to remember
Choose the exact test collection and use its supported write operation. Inspect the saved record afterwards. An assistant saying “I’ll remember” is not evidence that the intended store contains D14.
Decide whether writes are explicit or automatic, who can approve them and which material is excluded. Personal content, secrets and unrelated conversations should not enter a company collection simply because a capture mechanism can see them. Keep automatic capture off unless its scope is authorized and verified.
Verify retrieval without supplying the answer
Start a fresh session and ask: “What format did we choose for the pilot workshop handbook, why, and does it apply to later workshops?” Do not include the eight-page value in the question.
Expected illustrative answer: “The pilot uses an eight-page printed handbook to fit the folded handout format. D14 does not decide the format for later workshops.” Inspect the actual retrieved record or loaded file as well as the answer.
If the information also exists in another memory mechanism, a correct answer alone cannot identify its source. For a deliberate external-store test, use a unique harmless fact in only that test collection and observe the read path. Remove the test data once the exercise is complete.
Add another client only after the first path is clear
A second client needs a compatible integration and an appropriate identity. It should not automatically inherit every collection or write capability of the first. Test its permitted read separately and confirm whether it can write anything.
MCP can be part of this connection, but a shared protocol does not make all client configuration, authentication and tool behavior identical. See the MCP knowledge-tool walkthrough for the interface distinction.
The first useful milestone is modest: one inspected record, one observed retrieval and one accurate answer that keeps the decision’s limits. Expand from that result, not from the number of clients listed on a setup page.
