# Tool Highlight: Atlaso — One MCP Memory That Follows You Across Claude Code, Cursor, and Codex

> A memory layer that connects over MCP so every coding agent you use recalls the same projects, decisions, and preferences. Free to start — but you're routing your working context through one brand-new vendor.

## Key takeaways

- Atlaso is a hosted memory layer that connects once over MCP and then lets every AI tool you use — Claude Code, Cursor, Codex, Claude Desktop, OpenCode, Antigravity, or anything that speaks MCP — recall the same context: your projects, decisions, and how you like to work.
- It launched on Product Hunt around 2026-08-06. The wedge is continuity across tools: instead of your memory being locked inside one assistant, it captures decisions, watch-outs, and open questions as you work and makes them one searchable, editable store.
- Per the vendor, secrets are scrubbed before anything is stored, and the memory is something you can see, search, and manage — not a black box. It's free to start; detailed paid tiers weren't public at writeup time.
- This is the individual-builder cut of cross-agent memory: the point isn't a team knowledge base, it's that your own three coding agents stop re-learning your codebase every session.
- The honest catch: it's brand-new with no track record, your working context lives in one vendor's store reachable through one API, and the secret-scrubbing claim is security-critical and not independently verified — try it on a non-sensitive project first.

**What it is:** Atlaso ([atlaso.ai](https://www.atlaso.ai/)) is a hosted memory layer that connects over [MCP](/posts/mcp-vs-function-calling.html) so every AI tool you use draws from one shared memory. Connect it once and, per the vendor, Claude Code, [Cursor](/stack/cursor), Codex, Claude Desktop, OpenCode, and Antigravity all recall the same context — your projects, your decisions, and the way you like to work. Anything else that speaks MCP can connect too. It launched on Product Hunt around **2026-08-06** under the line "one memory for every AI you use."
**Who it's for:** Solo builders and founders who run *more than one* [coding agent](/topics/coding-agents). If you drive Claude Code in the terminal, Cursor in the editor, and hand reviews to Codex, each one starts every session amnesiac — re-learning your stack, your naming conventions, and the decision you already made twice. Atlaso's wedge is continuity across those tools: the memory follows *you*, not the app. That's a different job from [Mem0 vs Zep vs Letta](/posts/cross-agent-memory-layer-memorix-vs-memsearch-vs-agentmemory-vs-memmy.html), which are memory layers you embed into a product for *your* users.
**Should you care:** If you've felt the tax of repeating yourself to three agents, yes — this is the least-friction attempt yet at fixing it, because it rides MCP instead of asking every tool to adopt a proprietary SDK. If you run a single agent, or you keep your context in an [AGENTS.md / CLAUDE.md](/posts/agents-md-vs-claude-md.html) file you commit to the repo, the payoff is smaller — that file already travels with the code.
What it actually does
Atlaso captures **decisions, watch-outs, and open questions** as you work, rather than dumping raw transcripts. That framing matters: useful [agent memory](/topics/agent-memory) is the [consolidation step](/posts/how-ai-agents-forget-memory-consolidation.html) — deciding what's worth keeping and what to drop — not a firehose of everything you typed. The store is one place you can **see, search, and manage**, which is the right default; a memory you can't inspect or edit is a liability the first time it remembers something wrong.
The distinction worth holding onto: this is a **memory store**, not the [Claude memory tool](/posts/memory-tool-vs-memory-stores-anthropic-agent-memory.html). The Claude memory tool is a protocol your agent uses to read and write files you host; Atlaso is a hosted service that does the hosting and the write-consolidation for you, exposed to every agent through one MCP endpoint. If you'd rather own the backend, [Claude's memory tool](/posts/claude-memory-tool-explained.html) plus your own storage is the build-it-yourself path.
How to start
- Sign up at [atlaso.ai](https://www.atlaso.ai/) and get your connection details.
- Add Atlaso as a **remote [MCP server](/topics/mcp)** in your agent — the same flow you'd use to [authenticate any remote MCP server](/posts/how-to-authenticate-a-remote-mcp-server.html). It's supported in Claude Code, Cursor, Codex, Claude Desktop, OpenCode, and Antigravity.
- Work normally. It captures decisions and open questions as you go; when you switch tools, the new one recalls what the last one learned.

Pricing
- **Free to start.** Atlaso advertises a free entry point and describes itself as "backed by original memory research."
- **Paid tiers:** not detailed publicly at the time of writing. Treat anything beyond the free tier as "check the site," and — as with any hosted memory service — ask about **export** before you accumulate context you'd hate to lose.

The honest catch
Three things to weigh before you route your working memory through it.
**You're renting your context.** This is a brand-new hosted service with no track record. Every decision and watch-out your agents accumulate lives in one vendor's store, reachable through one vendor's API. The convenience *is* the lock-in — the longer you run, the more your memory-of-record lives somewhere you don't control. Confirm there's an export path before you commit anything important.
**Secret-scrubbing is a claim, not a guarantee you can see.** A tool that watches your coding sessions to capture "decisions and watch-outs" is, by construction, reading context that can include tokens, keys, and internal hostnames. Atlaso says secrets are scrubbed before storage — which is exactly the right promise and exactly the one you can't independently verify from the outside. The safe posture is the one you'd take with any agent that holds credentials: assume the model [should never see the key](/posts/non-human-identity-ai-agent-credentials-without-a-password.html), and test on a non-sensitive project before you trust it with a real one.
**"Backed by memory research" isn't a benchmark.** Recall quality is the whole game for a memory layer, and there's no public [LOCOMO-style number](/posts/ai-agent-memory-benchmarks-locomo-mem0-zep.html) for Atlaso yet. Whether it surfaces the *right* decision at the right moment — versus burying it or recalling a stale one — is something only your own use will tell you.
**Bottom line:** The most promising framing of cross-tool memory to date — ride MCP, follow the user, keep the store inspectable — aimed squarely at the builder juggling [three coding agents at once](/posts/skills-vs-subagents-vs-mcp-which-claude-code-extension.html). Try it on a throwaway project, verify the scrubbing against a test secret, and keep an export plan in your back pocket. If it holds up, never re-briefing your third agent is a real daily win.

## FAQ

### What is Atlaso?

A hosted memory layer for AI tools, launched on Product Hunt around 2026-08-06, that connects over the Model Context Protocol (MCP) so multiple agents share one persistent memory of your projects, decisions, and working style. You connect once and every connected tool recalls the same context.

### Who is it for?

Individual builders and solo founders who run more than one coding agent — say Claude Code for terminal work, Cursor in the editor, and Codex for reviews — and are tired of re-explaining the same architectural decisions to each one every session.

### Which tools does it connect to?

Per Atlaso, it works with Claude Code, Cursor, Codex, Claude Desktop, OpenCode, and Antigravity today, and anything else that speaks MCP can connect too.

### How do I start?

Connect Atlaso as an MCP server to your agent (the same way you add any remote MCP server), then work normally — it captures decisions, watch-outs, and open questions as you go, and the memory is searchable and editable. It's free to start.

### How is it different from Mem0 or AgentPrizm?

Mem0 and AgentPrizm are memory infrastructure you wire into an app you build; Atlaso is aimed at your own multi-tool workflow — the memory follows you as a user across the coding agents you already use, rather than being a store your product reads and writes for its end users.
