Claude-Mem seamlessly preserves context across sessions by automatically capturing tool usage observations, generating semantic summaries, and making them available to future sessions. This enables Claude to maintain continuity of knowledge about projects even after sessions end or reconnect.

Install with a single command:

npx claude-mem installOr install for OpenCode:

npx claude-mem install --ide opencodeOr install for Antigravity CLI (setup guide):

npx claude-mem install --ide antigravityOr install from the plugin marketplace inside Claude Code:

/plugin marketplace add thedotmack/claude-mem
/plugin install claude-mem

Restart Claude Code. Context from previous sessions will automatically appear in new sessions.

Note:Claude-Mem is also published on npm, butnpm install -g claude-meminstalls theSDK/library only— it does not register the plugin hooks or set up the worker service. Always install vianpx claude-mem installor the/plugincommands above.

Install claude-mem as a persistent memory plugin on OpenClaw gateways with a single command:

curl -fsSL https://install.cmem.ai/openclaw.sh | bashThe installer handles dependencies, plugin setup, AI provider configuration, worker startup, and optional real-time observation feeds to Telegram, Discord, Slack, and more. See the OpenClaw Integration Guide for details.

Claude-Mem provides intelligent memory search through 4 MCP tools following a token-efficient 3-layer workflow pattern:

The 3-Layer Workflow:

How It Works:

Available MCP Tools:

Example Usage:

// Step 1: Search for index
search(query="authentication bug", type="bugfix", limit=10)
// Step 2: Review index, identify relevant IDs (e.g., #123, #456)
// Step 3: Fetch full details
get_observations(ids=[123, 456])

See Search Tools Guide for detailed examples.

Claude-Mem offers a beta channel with experimental features like Endless Mode (biomimetic memory architecture for extended sessions). Switch between stable and beta versions from the web viewer UI at http://localhost:37777 → Settings.

See Beta Features Documentation for details on Endless Mode and how to try it.

If you see an error like:

npm : The term 'npm' is not recognized as the name of a cmdletMake sure Node.js and npm are installed and added to your PATH. Download the latest Node.js installer from https://nodejs.org and restart your terminal after installation.

Settings are managed in ~/.claude-mem/settings.json (auto-created with defaults on first run). Configure AI model, worker port, data directory, log level, and context injection settings.

See the Configuration Guide for all available settings and examples.

Claude-Mem supports multiple workflow modes and languages via the CLAUDE_MEM_MODE setting.

This option controls both:

Edit your settings file at ~/.claude-mem/settings.json:

{
  "CLAUDE_MEM_MODE": "code--zh"
}

Modes are defined in plugin/modes/. To see all available modes locally:

ls ~/.claude/plugins/marketplaces/thedotmack/plugin/modes/| Mode | Description | |---|---| | code | Default English mode | | code--zh | Simplified Chinese mode | | code--ja | Japanese mode |

Language-specific modes follow the pattern code--[lang] where [lang] is the ISO 639-1 language code (e.g., zh for Chinese, ja for Japanese, es for Spanish).

Note:

code--zh(Simplified Chinese) is already built-in — no additional installation or plugin update is required.

See the Development Guide for build instructions, testing, and contribution workflow.

If experiencing issues, describe the problem to Claude and the troubleshoot skill will automatically diagnose and provide fixes.

See the Troubleshooting Guide for common issues and solutions.

Create comprehensive bug reports with the automated generator:

cd ~/.claude/plugins/marketplaces/thedotmack
npm run bug-report
