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

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();
