Implement the MessageStore, RunStore, InterruptStore, MetadataStore contracts for @tanstack/ai-persistence against any database. defineAIPersistence, composePersistence overrides, critical invariants (full-replace saveThread, optional loadThread limit/before hint, insert-if-absent createOrResume and interrupt create), authorize thread access, runPersistenceConformance testkit. Use whenever you need server persistence — the package ships contracts, not a backend for your database.
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
# Persistence Stores
> Builds on **ai-persistence** and **ai-persistence/server**.
`@tanstack/ai-persistence` ships **contracts**, not a backend for your
database. An adapter is an object with a `stores` map; implement the stores you
need against whatever you already run and hand the result to
`withPersistence`. The core never inspects your tables, so the schema is yours.
Use `memoryPersistence()` for dev and tests. Everything durable is an adapter
you write. This skill is the contract reference; the per-stack recipes that
write a `chat-persistence.ts` into an app are
`ai-persistence/build-{drizzle,prisma,cloudflare,custom}-adapter`, and
a complete `node:sqlite` implementation lives in
`examples/ts-react-chat/src/lib/sqlite-persistence.ts`.
## Choose a shape
```ts
import { defineAIPersistence } from '@tanstack/ai-persistence'
import type { ChatWithInterruptsPersistence } from '@tanstack/ai-persistence'
import { messages, runs, interrupts } from './stores'
// Sparse is fine — only implement what you need.
export const persistence: ChatWithInterruptsPersistence = defineAIPersistence({
stores: {
messages, // required for withPersistence / reconstructChat

How to install
mdr add tanstack/ai/ai-persistence/stores@sha256:0d1713b28deb2053The line at the top of this page pins the label git:20261027.2f86841, 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.
