Memory Layer for Claude Code

CLI tool and IDE integration with MCP server support for development workflows. Give your Claude Code sessions persistent memory.

Installation

Claude Code 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 Code config file at ~/.claude/config.json:

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

Available Tools

Once configured, Claude Code 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 Code can automatically use memory tools:

$ claude code

You: Remember I'm refactoring the auth system to use Supabase
Claude: [Uses memory_add to store this context]

// Later session:
You: What am I working on with auth?
Claude: [Uses memory_recall]
        You're refactoring the auth system to use Supabase.

IDE Integration

Claude Code integrates with VS Code and other IDEs. The MCP server provides memory tools across all integrated environments.

Project Context

Memories are scoped to your API key. You can organize them by project using agent IDs or custom tags within memory operations.

Troubleshooting

MCP server not loading

Verify Node.js and npm are installed. Restart Claude Code after modifying the config file.

Authentication errors

Check your API key is valid. Get a new key from your dashboard.
