Documentation Overview

SUBSTRATE MCP Server

Persistent AI entity framework with causal memory, emotional state, and identity continuity.

SUBSTRATE gives AI entities real cognitive infrastructure — not just a prompt, but a living architecture with 94 cognitive layers including episodic memory, value systems, emotional affect, theory of mind, and narrative identity.

Built by Garmo Labs.

Quick Start

1. Get your API key

Sign up free at garmolabs.com/substrate.html

2. Install for Claude Desktop

Terminal
npx @garmolabs/substrate-mcp --install YOUR_API_KEY

Restart Claude Desktop. SUBSTRATE will appear in your MCP tools.

3. Or use programmatically

server.ts
const substrate = require('@garmolabs/substrate-mcp');
const client = new substrate.Client('sk_sub_...');

// Talk to your entity
const response = await client.call('respond', { message: 'Hello' });

// Check emotional state
const emotion = await client.call('get_emotion_state', {});

// Search memories
const memories = await client.call('memory_search', { query: 'last meeting' });

// List all 31 available tools
const tools = await client.listTools();
