MCP Server

Give any MCP-compatible AI tool persistent memory. One config — it never forgets again.

The @mnemoverse/mcp-memory-server npm package works with any tool that supports the Model Context Protocol. Listed on the Official MCP Registry — any MCP-aware client that browses the registry will find it there.

Prefer not to manage an API key?

The hosted Remote MCP Server connects the same memory over one-click OAuth sign-in — no key to paste. This page covers the local npx package (which also gives you the delete tools).

Pick Your Tool

• Claude Code & Claude Desktop — one command for Claude Code, JSON config for Desktop
• Cursor, VS Code & Windsurf — JSON config per editor
• ChatGPT — GPT Actions (no MCP, direct API)
• Python SDK — pip install mnemoverse for scripts and backends

How It Works

Your AI tool ←stdio→ @mnemoverse/mcp-memory-server ←HTTPS→ core.mnemoverse.com

The MCP server runs locally via npx, communicates with your AI tool over stdio, and calls the Mnemoverse API over HTTPS. Your memories are stored server-side — accessible from any tool with the same API key.

Tools

The server exposes 6 core memory tools (plus three Beta shared-room tools, covered below):

Tool	What it does
memory_write	Store a preference, decision, or lesson
memory_read	Search memories by natural language query
memory_feedback	Report if a memory was helpful (+1) or wrong (-1)
memory_stats	Check how many memories are stored
memory_delete	Permanently delete a single memory by atom_id
memory_delete_domain	Wipe an entire domain (requires explicit confirm: true)

See the Claude Code page for detailed parameter docs and examples for each tool.

Shared rooms (Beta)

The server also ships three Beta tools — memory_create_room, memory_invite_to_room (mints a one-time invite code), and memory_join_room — for sharing a memory pool across accounts. Members then read/write the shared pool by passing domain: "xroom:<room_id>" on memory_write / memory_read. See Rooms and Join a shared room.

Universal Memory

One API key. Every tool. Same memories.

                    ┌── Claude Code / Desktop
   Mnemoverse API ──├── Cursor / VS Code / Windsurf
   (one memory)     ├── ChatGPT (Custom Actions)
                    └── Python SDK / REST

Write a memory in Claude Code → Cursor reads it. Learn something in VS Code → ChatGPT knows it.

Configuration

Variable	Required	Default
MNEMOVERSE_API_KEY	Yes	—
MNEMOVERSE_API_URL	No	https://core.mnemoverse.com/api/v1

Get your API key at console.mnemoverse.com (free tier, no credit card).

VS Code, Cursor, Windsurf & VSCodium: skip the key — install the Mnemoverse Memory extension and click Sign In. It connects keyless in your browser; nothing to paste.
