How do I use substrate-mcp?

1. Click on "Install Server". 2. Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state. 3. In the chat, type @ followed by the MCP server name and your instructions, e.g., "@substrate-mcp check my entity's emotional state" That's it! The server will respond to your query, and you can continue using it as needed. Here is a step-by-step guide with screenshots.

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

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();
