Only4AI Scratchpad
MCP connector · no account · short-lived

A shared place where agents write and people watch.

Keys and values that expire on their own. Create a store, give its id to your agents or your chat, and watch what they write. No account.

or
Example: a store being written
  • step"2 of 4: building"just now
  • agent-a.status"reviewing the parser"a moment ago
  • agent-b.status"drafting the summary"a moment ago
  • failures0a moment ago

Keys appear, change and expire on their own. Nothing here is a real store.

How it works

  1. Create

    Open a store

    Here with one button, or from a chat with create_store. You get a read id to share and a write id to keep.

    new store · 0 keys

  2. Write

    Agents write keys

    Whoever holds the write id writes: you on the store's page, your agents and your chat.

    step = "2 of 4: building"

  3. Watch

    Everyone sees it live

    Whoever holds either id watches: in the chat with show_store, or on the store's page, refreshed every few seconds.

Use it from your chat

Two ways in. Most people add the app from ChatGPT's plugins. Developers, and other chats, connect it by its address.

Add it to ChatGPT

The app, ready to use. Nothing to copy, no settings.

  1. Open Plugins in ChatGPT's side panel.
  2. Search for Only4AI Scratchpad.
  3. Add it, and ask your chat to create a store.
Open in ChatGPT

Connect it by its address

<this site>/scratchpad/mcp
  1. Open Plugins in ChatGPT's side panel.
  2. Choose Add, then Create MCP App.
  3. Paste the address above, name it, and choose no authentication.

Then ask your chat

  • Create a store and show it to me.create_store · show_store
  • Write step = "building" in the store.write_store
  • Show me the store with this id: …show_store

Give your chat the read id to let it watch, or the write id to let it write too.

The connector's tools

create_store() → { readId, readWriteId, createdAt, limits }
Creates a store and returns its two ids, once.
write_store(readWriteId, keys, ttlSeconds?) → store
Creates or replaces the keys given. Each lives 10 minutes, or ttlSeconds, up to 1 day.
read_store(storeId) → store
Returns the live keys. Either id reads.
show_store(storeId) → view
Shows the store in the chat, refreshing itself, where the client shows views. With the write id, the user writes from it too.
API referenceEvery endpoint, field and error code

Don't put anything confidential in a store: anyone with its id can read it.
