The plugin exposes two MCP tools, deepmem_write for storing LLM-extracted conversation facts and deepmem_search for hybrid semantic search, and requires a DeepMem cloud API key prefixed dm_live_ obtained from deepmem.dev. Installation runs via the command /plugin marketplace add deepmemteam/deepmem-claude-plugin followed by /plugin install deepmem@deepmem, with source hosted at github.com/deepmemteam/deepmem.", "body_md": "[DeepMem](https://deepmem.dev) as a Claude Code plugin - persistent,\nsemantically searchable memory across all your Claude Code sessions.\n\nThis repo is dual-standard:\n\n- **Open Plugins** ([agent-plugins.org](https://agent-plugins.org) ) manifest at\nthe root (`plugin.json` +`mcp.json` ) - for Cursor's plugin scanner and any\nOpen Plugins-compatible client.\n- **Claude Code plugin marketplace** under`.claude-plugin/` +`plugins/` .\n\n```\n/plugin marketplace add deepmemteam/deepmem-claude-plugin\n/plugin install deepmem@deepmem\n```\n\nSettings -> MCP -> Add new MCP server, or `~/.cursor/mcp.json`:\n\n```\n{\n  \"mcpServers\": {\n    \"deepmem\": {\n      \"url\": \"https://deepmem.dev/mcp\",\n      \"headers\": { \"Authorization\": \"Bearer ${env:DEEPMEM_API_KEY}\" }\n    }\n  }\n}\n```\n\nThe plugin needs a DeepMem cloud API key (`dm_live_...`):\n\n1. \nGet one at **[https://deepmem.dev](https://deepmem.dev)** (sign up -> dashboard -> create key)\n2. \nRun `/deepmem:setup` and follow the prompts, or manually add to`~/.claude/settings.json` :\n\n```\n{\n  \"env\": {\n    \"DEEPMEM_API_KEY\": \"dm_live_xxx\"\n  }\n}\n```\n\n3. \nRestart Claude Code, then check `/mcp` -`deepmem` should show connected.\n\n- `deepmem_write` - store conversation facts (LLM-extracted, embedded, persisted)\n- `deepmem_search` - hybrid semantic search over stored memories\n\n- Cloud: [https://deepmem.dev](https://deepmem.dev)\n- Source: [https://github.com/deepmemteam/deepmem](https://github.com/deepmemteam/deepmem)", "url": "https://wpnews.pro/news/show-hn-memory-plugin-for-coding-agents-that-remembers-your-coding-chat-history", "canonical_source": "https://github.com/deepmemteam/deepmem-claude-plugin", "published_at": "2026-09-14 13:23:56+00:00", "updated_at": "2026-09-14 13:47:35.315649+00:00", "lang": "en", "topics": ["ai-agents", "ai-tools", "developer-tools", "ai-products"], "entities": ["DeepMem", "Claude Code", "Cursor", "Open Plugins", "agent-plugins.org", "deepmem.dev", "deepmemteam/deepmem-claude-plugin", "deepmem_write"], "alternates": {"html": "https://wpnews.pro/news/show-hn-memory-plugin-for-coding-agents-that-remembers-your-coding-chat-history", "markdown": "https://wpnews.pro/news/show-hn-memory-plugin-for-coding-agents-that-remembers-your-coding-chat-history.md", "text": "https://wpnews.pro/news/show-hn-memory-plugin-for-coding-agents-that-remembers-your-coding-chat-history.txt", "jsonld": "https://wpnews.pro/news/show-hn-memory-plugin-for-coding-agents-that-remembers-your-coding-chat-history.jsonld"}}
