Mnemoverse Memory MCP 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…. Its 10 documented tools cover memory, room.

People connecting memory tools to Claude, Cursor, VS Code, or another MCP client. The project is written in TypeScript.

01 · Install Mnemoverse Memory

before you install - you'll need

Set MNEMOVERSE_API_KEY, MNEMOVERSE_API_URL before connecting.

Claude Code

claude mcp add mnemoverse-mcp-memory-server --transport http https://mcp.mnemoverse.com/mcp

Claude Desktop / Cursor / VS Code - add to config

{
  "mcpServers": {
    "mnemoverse-mcp-memory-server": {
      "url": "https://mcp.mnemoverse.com/mcp"
    }
  }
}

Same JSON for Cursor. For VS Code, rename the top-level key from `mcpServers` to `servers`.

Security posture

What to check before giving this server access to your agent - from the registry, GitHub, and our own probes. We don't score safety; we show what's verifiable.

runs as local process (stdio) - runs on your machine with your user's permissions · remote - your agent's requests go to mcp.mnemoverse.com

endpoint auth requires authentication - rejected our unauthenticated MCP initialize

registry namespace io.github.mnemoverse is GitHub-verified and matches the repo owner

03 · What Mnemoverse Memory can do

Prose above is summarized from the project's README and registry record - no invented capabilities.

What you can build

With this server connected, an agent can search memories by natural language query (optional recency ordering, time bounds, author exclusion), list newest memories first - no query, check how many memories stored, which domains exist, and create a shared memory room.
