What it does

Tanstack AI Memory Mem0 is an agent skill from TanStack/ai. Use when wiring mem0() from @tanstack/ai-memory/mem0 — a hosted memory adapter that talks to a mem0 server over plain HTTP (no SDK peer). Requires a running mem0 server.

Its SKILL.md is about 420 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering. It works with Mem0 and TanStack. The repository describes itself as: 🤖 Type-safe, provider-agnostic TypeScript AI SDK for streaming chat, tool calling, agents, and multimodal apps across OpenAI, Anthropic, Gemini, React, Vue, Svelte, and Solid. The licence is MIT.

When your agent uses it

  • Wiring mem0() from @tanstack/ai-memory/mem0 — a hosted memory adapter that talks to a mem0 server over plain HTTP (no SDK peer)

Example prompts

  • “/tanstack-ai-memory-mem0”

Requirements

  • A credential in MEM0_ADMIN_API_KEY

What it can do on your machine

Read from SKILL.md and the folder at commit 5a41239. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md (its code samples are typescript).

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • MEM0_ADMIN_API_KEY

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Tanstack AI Memory Mem0 loads about 419 tokens when it runs. Until then it costs about 48 tokens; SKILL.md has 125 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~48
When it runs · the whole SKILL.md, loaded when a task matches
~419

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Use when wiring mem0() from @tanstack/ai-memory/mem0 — a hosted memory adapter that talks to a mem0 server over plain HTTP (no SDK peer). Requires a running mem0 server.

mem0 Memory Adapter

Hosted recall/save adapter backed by a mem0 server. mem0 owns extraction and ranking server-side. Talks to the server over plain HTTP — no SDK peer dependency.

Setup

ts
import { memoryMiddleware } from '@tanstack/ai-memory'
import { mem0 } from '@tanstack/ai-memory/mem0'

// Build per request from the server-validated session — never from req.body.
function memoryFor(session: { userId: string; threadId: string }) {
  const memory = mem0({ user: session.userId }) // baseUrl defaults to MEM0_URL

  return memoryMiddleware({
    adapter: memory,
    scope: { threadId: session.threadId, userId: session.userId },
  })
}

Requires a running mem0 server (self-hosted or hosted). Point it via baseUrl (or MEM0_URL); pass apiKey (or MEM0_ADMIN_API_KEY) when secured.

Options

  • user — mem0 user_id (falls back to scope.userId, then 'demo-user').
  • baseUrl — mem0 server URL (default MEM0_URL or http://localhost:8000).
  • apiKey — bearer token (default MEM0_ADMIN_API_KEY).
  • rerank (default true), threshold (default 0.1) — search tuning.

Scope fields: requests send user_id and run_id (scope.threadId). tenantId and namespace are not sent — encode multi-tenant isolation into user if needed.

save posts the { user, assistant } turn to /memories; recall queries /search and renders the results into the system prompt. mem0 exposes no LLM tools.
