@mnemoverse/mcp-memory-server

Hosted memory for AI agents that learns which facts matter. Feedback re-ranks recall — a Rescorla-Wagner update on the prediction error, not a similarity score — so what helped rises and what misled sinks, with a bounded recency tie-breaker for fresh memories. The engine also ships consolidation (HDBSCAN clustering, with Von Restorff protection so distinctive memories survive compression). One API key works across Claude, Cursor, VS Code, ChatGPT, and any MCP client.

Memory that persists across sessions, projects, and tools — and improves with use. Hosted, so there's no infrastructure to run, and not locked to a single cloud.

⭐ If Mnemoverse saves you from re-explaining context to your agents, star the repo. It helps other builders find it.

Quick Start

Sign up at console.mnemoverse.com — takes 30 seconds, no credit card.

2. Connect to your AI tool

Claude Code — add via CLI:

claude mcp add mnemoverse -s user \
  -e MNEMOVERSE_API_KEY=mk_live_YOUR_KEY \
  -e MNEMOVERSE_API_URL=https://core.mnemoverse.com/api/v1 \
  -- npx -y @mnemoverse/mcp-memory-server@latest

Cursor — click to install, or add to .cursor/mcp.json:

{
  "mcpServers": {
    "mnemoverse": {
      "command": "npx",
      "args": [
        "-y",
        "@mnemoverse/mcp-memory-server@latest"
      ],
      "env": {
        "MNEMOVERSE_API_KEY": "mk_live_YOUR_KEY",
        "MNEMOVERSE_API_URL": "https://core.mnemoverse.com/api/v1"
      }
    }
  }
}

VS Code — add to .vscode/mcp.json (note: VS Code uses servers, not mcpServers):

{
  "servers": {
    "mnemoverse": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@mnemoverse/mcp-memory-server@latest"
      ],
      "env": {
        "MNEMOVERSE_API_KEY": "mk_live_YOUR_KEY",
        "MNEMOVERSE_API_URL": "https://core.mnemoverse.com/api/v1"
      }
    }
  }
}

Windsurf — add to ~/.codeium/windsurf/mcp_config.json:

{
  "mcpServers": {
    "mnemoverse": {
      "command": "npx",
      "args": [
        "-y",
        "@mnemoverse/mcp-memory-server@latest"
      ],
      "env": {
        "MNEMOVERSE_API_KEY": "mk_live_YOUR_KEY",
        "MNEMOVERSE_API_URL": "https://core.mnemoverse.com/api/v1"
      }
    }
  }
}

More MCP clients — same server, different config file:

Zed — add to ~/.config/zed/settings.json (Zed uses `context_
