Show HN: Memory plugin for coding agents that remembers your coding&chat history

DeepMem as a Claude Code plugin - persistent, semantically searchable memory across all your Claude Code sessions.

This repo is dual-standard:

• Open Plugins (agent-plugins.org ) manifest at the root (plugin.json +mcp.json ) - for Cursor's plugin scanner and any Open Plugins-compatible client.
• Claude Code plugin marketplace under.claude-plugin/ +plugins/ .

/plugin marketplace add deepmemteam/deepmem-claude-plugin
/plugin install deepmem@deepmem

Settings -> MCP -> Add new MCP server, or ~/.cursor/mcp.json:

{
  "mcpServers": {
    "deepmem": {
      "url": "https://deepmem.dev/mcp",
      "headers": { "Authorization": "Bearer ${env:DEEPMEM_API_KEY}" }
    }
  }
}

The plugin needs a DeepMem cloud API key (dm_live_...):

Get one at https://deepmem.dev (sign up -> dashboard -> create key) 2. Run /deepmem:setup and follow the prompts, or manually add to~/.claude/settings.json :

{
  "env": {
    "DEEPMEM_API_KEY": "dm_live_xxx"
  }
}

Restart Claude Code, then check /mcp -deepmem should show connected.
