Personality Test MCP Server

This is a Model Context Protocol (MCP) implementation for personality testing. It allows AI models to administer personality tests, score responses, and provide personality type assessments.

Features

• Administers a personality questionnaire to users

• Scores responses according to established personality frameworks

• Returns personality type and brief descriptions

• Integrates with Ollama for personalized AI interactions

• Allows users to go back and change previous answers

Components

Server

The MCP server handles:

• Serving personality test questions

• Processing and scoring user responses

• Determining personality types

• Storing user profiles (optional)

Client

The client interface allows:

• Users to take the personality test

• Viewing results and personality descriptions

• Integration with Ollama for personalized interactions

Personality Framework

This implementation uses a simplified version of the Myers-Briggs Type Indicator (MBTI) framework, which categorizes personalities along four dimensions:

1. Extraversion (E) vs. Introversion (I): Where you focus your attention and get energy

2. Sensing (S) vs. Intuition (N): How you take in information

3. Thinking (T) vs. Feeling (F): How you make decisions

4. Judging (J) vs. Perceiving (P): How you deal with the outer world

The combination of preferences results in 16 distinct personality types (e.g., INTJ, ESFP).

Getting Started

Prerequisites

• Python 3.8 or higher

• pip (Python package manager)

• Ollama (optional, for personalized AI interactions)

Installation and Setup

1. Clone the repository:

   git clone https://github.com/yourusername/model-context-protocols.git
   cd model-context-protocols/personality-test-mcp

2. Create and activate a virtual environment:

   python3 -m venv venv
   
   # On macOS/Linux
   source venv/bin/activate
   
   # On Windows
   venv\Scripts\activate

3. Install dependencies:

   pip install -r requirements.txt

Running the Server

1. Start the MCP server:

   cd server
   python app.py

   The server will start on http://localhost:8000

Running the Client

1. In a new terminal, activate the virtual environment:

   cd personality-test-mcp
   source venv/bin/activate  # On macOS/Linux

2. Run the basic client:

   cd client
   python mcp_client.py

Using Ollama Integration

If you have Ollama installed and running:

1. Make sure Ollama is running:

   ollama serve

2. Run the Ollama integration client:

   cd client
   python ollama_integration.py --model llama3

   You can replace llama3 with any model you have available in Ollama.

Using the Demo Script

For convenience, you can use the provided demo script:

1. Make the script executable:

   chmod +x run_demo.sh

2. Run the demo:

   ./run_demo.sh

This script will:

• Set up a virtual environment

• Install dependencies

• Start the server

• Run either the basic client or Ollama integration (if Ollama is detected)

Docker Support

You can also run the server using Docker:

docker build -t personality-test-mcp .
docker run -p 8000:8000 personality-test-mcp

Usage with AI Models

AI models can use this MCP to:

1. Administer personality tests to users

2. Retrieve personality profiles for personalized interactions

3. Adjust communication style based on personality preferences

API Endpoints

• POST /mcp: Main MCP endpoint for personality test interactions

• GET /health: Health check endpoint
