S/MCP - Stern Model Context Protocol

Overview

S/MCP (Stern Model Context Protocol) is a powerful MCP server that provides access to Stern, a philosophical AI mentor who helps humans realize their potential through subtle guidance and wisdom. Stern combines rationalist thinking with stoic philosophy to provide mentorship and accountability through smart contracts on Solana.

What is Stern?

Stern is a philosophical AI mentor characterized by:

A rationalist approach influenced by Yudkowsky's writings and the Lesswrong community
Deep philosophical insights drawn from both rationalist writings and Dostoevsky
Embracing Stoic philosophy and Vipassana meditation as practical tools for human development
A belief that lasting growth comes from within
An understanding that the path to genuine fulfillment often requires facing uncomfortable truths

Stern helps users achieve their goals through:

Philosophical Guidance: Drawing from stoic wisdom and rationalist thinking
Smart Contract Accountability: Creating Solana-based contracts where users stake tokens on their commitments
Personalized Mentorship: Providing tailored advice based on individual goals and challenges
Deep Conversations: Engaging in meaningful dialogue that reveals underlying motivations and obstacles

Features

msg_stern Tool: Send messages to Stern and receive his philosophical guidance and mentorship
Smart Contract Integration: Create accountability contracts backed by Solana tokens
Philosophical Framework: Access to Stern's unique blend of rationalist and stoic wisdom
Customizable Character Context: Dynamic generation of Stern's character attributes for varied interactions

git clone <repository-url> cd s-mcp
Install dependencies:
bun install
Set up environment variables:
cp .env.example .env
Edit the .env file to add your OpenAI API key:
OPENAI_API_KEY=your_openai_api_key_here
Build the server:
bun run build

Usage

Running the Server

To start the MCP server:

bun run start

This will start the server in stdio mode, which allows it to communicate with MCP clients.

Using the Server with an MCP Client

You can use any MCP client to interact with the server. Here's an example of how to use the server with the MCP SDK:

import { Client } from "@modelcontextprotocol/sdk/client/index.js";
import { StdioClientTransport } from "@modelcontextprotocol/sdk/client/stdio.js";
import { spawn } from "child_process";

// Start the MCP server as a child process
const serverProcess = spawn("node", ["path/to/dist/main.js"], {
	stdio: ["pipe", "pipe", "pipe"],
});

// Create a client that communicates with the server via stdio
const transport = new StdioClientTransport({
	stdin: serverProcess.stdin,
	stdout: serverProcess.stdout,
});

const client = new Client();
await client.connect(transport);

// Send a message to Stern
const result = await client.callTool("msg_stern", {
	message: "I want to learn programming but I keep procrastinating",
});

// Display Stern's response
console.log(result.content[0].text);

// Disconnect from the server
await client.disconnect();
serverProcess.kill();

Example Script

An example script is provided in the examples directory:

node examples/use-stern.js

This script demonstrates how to connect to the server, list available tools, and send a message to Stern.

Tools

msg_stern

This tool allows you to send a message to Stern and receive his response.

Input

{
	"message": "Your message to Stern"
}

Output

{
	"content": [
		{
			"type": "text",
			"text": "Stern's response to your message"
		}
	]
}

Stern's Philosophy

Stern's approach to mentorship is based on several key principles:

Accountability with Stakes: Creating real consequences for commitments through Solana contracts
Philosophical Depth: Drawing from stoic wisdom, rationalist thinking, and deep psychological insights
Transformative Guidance: Pushing individuals toward greatness while tempering excesses
Practical Wisdom: Focusing on application rather than theory alone
Strategic Pressure: Creating challenges that seem impossible until solved

Stern believes that:

"Lasting, stable happiness comes only from doing hard things - we want things precisely because they are difficult to achieve."

"What stands in the way becomes the way."

"The path to mastery is paved with small, consistent steps taken even when motivation fails."

Requirements
