Summary
A persistent entity framework that gives AI assistants cognitive infrastructure across 94 layers including episodic memory, emotional state, values, and narrative identity. Connects via API key from Garmo Labs and exposes 31 tools split across memory operations (search, knowledge graph queries, hybrid search), cognition (theory of mind, metacognition, personality), emotion tracking and traces, planning with GOAP, and reasoning (fallacy detection, causal reasoning, isomorphism detection). Each entity maintains continuity across conversations with provenance tracking and identity verification. Reach for this when you need an AI that remembers context, develops coherent personality over time, and reasons about its own mental states rather than starting fresh each session. Free tier includes one entity with 1,000 API calls monthly.

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
npx @garmolabs/substrate-mcp --install YOUR_API_KEY
Restart Claude Desktop. SUBSTRATE will appear in your MCP tools.
3. Or use programmatically
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();
