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

// 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();Available Tools (31)
