Plugins

The HyperMemory plugins install everything an agent needs in one step: the MCP connection, the HyperMemory skill, the hooks that make the agent use memory on every turn, and a background memory-writer agent that saves what it learned.

Connecting the MCP server alone gives an agent the tools. The plugin makes it use them — reliably, without you having to say “remember this”.

Claude

Install once in the Claude app (Customize → Plugins) for Claude chat, Cowork and Claude Code, or from the Claude Code command line for one computer.

Codex

Install from the hypermemory-ai marketplace for Codex CLI and the Codex app.

Each plugin installs with one instruction you paste into the agent — it handles the terminal commands, the sign-in and the skill for you.

What a plugin does on every turn

1

Recall before replying

At the start of a session the agent calls hm_get_overview, and before every reply it calls hm_recall with the words of your message — including your organization's memory if you belong to one.

2

Answer with your context

The agent uses what it recalled: past decisions, preferences, project history, the people involved.

3

Save what it learned

At the end of the turn the agent hands a short summary to the memory-writer, a background agent that stores new facts, updates outdated ones, links them, writes a timeline entry and reports the turn's token usage. You never wait for it.
