Documentation | 0Latency

Installation

Install the 0Latency MCP server globally via npm:

npm install -g @0latency/mcp-server

Or use it directly with npx (no installation required):

npx -y @0latency/mcp-server

Authentication

Get your API key from 0latency.ai and set it as an environment variable:

export ZEROLATENCY_API_KEY=zl_live_...

Your API key is used to authenticate all requests to the 0Latency memory API.

First Memory

Python SDK

Store and recall memories using the Python SDK:

from zerolatency import Memory

# Initialize the client
memory = Memory(api_key="zl_live_...")

# Store a memory
result = memory.seed(
    agent_id="assistant-1",
    facts=[{
        "text": "User prefers concise responses",
        "category": "preference"
    }]
)

# Recall memories
memories = memory.recall(
    agent_id="assistant-1",
    query="How should I format my responses?"
)

print(memories)

JavaScript SDK

Use the JavaScript SDK in Node.js or browser environments:

import { Memory } from '@0latency/sdk';

// Initialize the client
const memory = new Memory({ apiKey: 'zl_live_...' });

// Store a memory
await memory.seed({
    agentId: 'assistant-1',
    facts: [{
        text: 'User prefers dark mode',
        category: 'preference'
    }]
});

// Recall memories
const memories = await memory.recall({
    agentId: 'assistant-1',
    query: 'What are the user settings?'
});

console.log(memories);

MCP Setup

Connect 0Latency to Claude Desktop, Cursor, Windsurf, or any MCP-compatible client.
