Use when wiring memoryMiddleware from @tanstack/ai-memory into a chat() call — covers the recall/save adapter contract, scope shape and server-side scope security, the recall-inject / deferred-save lifecycle, choosing an adapter (inMemory, redis, hindsight, mem0, honcho), and devtools events.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# TanStack AI Memory Middleware

Use this when adding **server-side memory** to a `chat()` call. Everything lives in
`@tanstack/ai-memory`. A memory adapter is a single contract with two verbs — `recall`
and `save` — and the middleware is thin: it recalls into the system prompt before the
model runs and defers `save` after the turn finishes.

## When to reach for it

- A user expects "remember what I told you last time."
- Per-user or per-thread context that must survive across sessions.
- A hosted memory service (mem0, Honcho, Hindsight).

Do NOT use this just to keep recent messages — that's the `messages` array on `chat()`.
Memory is for cross-turn / cross-session recall, not within-turn history.

## Wire it up

```ts
import { chat, toServerSentEventsResponse } from '@tanstack/ai'
import { openaiText } from '@tanstack/ai-openai'
import { memoryMiddleware } from '@tanstack/ai-memory'
import { inMemory } from '@tanstack/ai-memory/in-memory'
import { requireSession } from './auth'

const memory = inMemory() // dev/tests only — see the in-memory skill

export async function POST(request: Request) {
  const { messages } = await request.json()
…

How to install

The exact contents, by fingerprint
mdr add tanstack/ai/tanstack-ai-memory@sha256:99b1b48f579b989e

The line at the top of this page pins the label git:20261022.f1b3f65, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
