The first connection may take a moment
Your Loomem "wakes up" the first time you use it — a few seconds. It's normal, whichever tool you connect from, and every time after that is instant. If a first attempt or tool scan times out, wait a few seconds and retry.
Open Connectors in Claude
In the Claude app go to Settings → Connectors, click the + at the top, and choose Add custom connector.
Add your address
Give it any Name (e.g. My Loomem). In Remote MCP server URL, paste the address from your email:
https://0000042.loomem.ai/mcpLeave the OAuth fields empty, then click Add.
Sign in with your key
A small Loomem sign-in page opens. Paste the key from your email and click Authorize:
xxxx-your-key-from-the-email-xxxxThat's it — your Loomem is connected. 🎉
What your plan can do
ChatGPT custom apps work on the web only (not the mobile app), and what Loomem can do depends on your plan:
Full — recall and save
ChatGPT can read your context and write new facts back to it. The complete Loomem experience.
Read-only
ChatGPT can search and recall your context, but can't save new memories yet. You can still add them from Claude or Codex.
Not supported
Free ChatGPT can't add custom apps. Use Claude, or upgrade to Plus or higher.
Turn on Developer mode
On the ChatGPT website, go to Settings → Apps → Advanced Settings and switch on Developer mode. (On Business/Enterprise/Edu an admin enables access first.)
Create the Loomem app
Go to Settings → Apps → Create. Name it anything, paste the address from your email as the MCP server URL, choose OAuth:
https://0000042.loomem.ai/mcpClick Scan Tools. A Loomem sign-in page opens — paste your key and click Authorize:
xxxx-your-key-from-the-email-xxxxDone
Once the tool scan finishes, click Create. Open a new chat and pick Loomem from the apps menu — it's connected. 🎉
One setup, CLI and IDE
Codex (OpenAI) works from the terminal and the IDE extension — they share one config, so you set this up once.
Add your Loomem
In a terminal, run this command — it uses the address from your email:
codex mcp add loomem --url https://0000042.loomem.ai/mcpSign in with your key
codex mcp login loomemA Loomem sign-in page opens in your browser. Paste the key from your email and click Authorize:
xxxx-your-key-from-the-email-xxxxCheck it's connected
codex mcp listYou should see loomem listed as enabled. Inside a Codex session, /mcp shows
the connected tools. That's it — your Loomem is connected. 🎉
Encrypted at rest
Your Loomem stores everything you save under an AES-256 key unique to your instance. We're not zero-knowledge — as the operator we can read it to support you — but a stolen storage dump can't read your context.
Running a self-hosted agent? Go fully local
Hermes
Both speak MCP, so they can use your hosted trial too. But self-hosted agents pair best with a self-hosted Loomem — a single small binary running right beside your agent, so its memory never leaves your machine. Get the standalone version →
