Markdown-first long-term memory shared across your coding agents: a local memtomem MCP server plus six memory skills (index, recall, remember, search, setup, status). Notes live in ~/.memtomem and are searchable from Hermes, Claude Code, Codex CLI and Kimi Code. Runs at user scope.

## Good to know before installing

The server is launched with `uvx --python 3.12` and downloaded from PyPI (memtomem[onnx]==0.6.9) on first start, with Python 3.12 if uv cannot find one; it runs as a stdio MCP server for the session and reads the directories you ask it to index. With a fresh BM25-only configuration nothing else leaves the machine; an existing memtomem configuration may enable Hugging Face model downloads, a remote embedding or LLM provider, Cohere reranking or search webhooks. At startup the server also reads the nearest .env found upward from its installed location inside uv's cache (normally ~/.env), setting variables not already present, outside Hermes's MCP environment filtering.

From the plugin's catalog listing.

## How to install

1. Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.

```bash
hermes plugins install memtomem
```

2. Said no? Turn it on later:

```bash
hermes plugins enable memtomem
```

3. Restart Hermes so it loads the plugin.

Some plugins also need a sign-in or settings: see the official page. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide: https://hermes-agent.nousresearch.com/docs/user-guide/features/plugins
