Memory Layer for Claude Desktop

Add persistent memory to Claude Desktop. Works across all conversations — your Claude remembers everything.

Installation

Claude Desktop supports the Model Context Protocol (MCP) natively. Install the 0Latency MCP server:

npm install -g @0latency/mcp-server

Configuration

Add the MCP server to your Claude Desktop config file:

macOS

Edit ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "0latency": {
      "command": "npx",
      "args": ["-y", "@0latency/mcp-server@latest"],
      "env": {
        "ZERO_LATENCY_API_KEY": "zl_your_api_key_here"
      }
    }
  }
}

Windows

Edit %APPDATA%\Claude\claude_desktop_config.json with the same configuration.

Available Tools

Once configured, Claude Desktop will have access to these memory tools:

• memory_add — Store memories from conversations
• memory_recall — Retrieve relevant context instantly
• memory_search — Semantic search across all memories
• memory_list — Browse and paginate stored memories
• memory_delete — Remove specific memories
• memory_graph — Explore entity relationships
• list_agents — Manage multiple agent namespaces

Usage Example

Once configured, Claude can automatically use memory tools:

You: Remember that my timezone is PST
Claude: [Uses memory_add to store this]

// Later, in a different conversation:
You: What time is it for me?
Claude: [Uses memory_recall to check your timezone]
        Since you're in PST, it's currently...

Conversation Persistence

Memories persist across all Claude Desktop conversations. They're scoped to your API key, so your Claude always has access to relevant context no matter which conversation you're in.
