Multi-Model Advisor

A Model Context Protocol (MCP) server that queries multiple Ollama models and combines their responses, providing diverse AI perspectives on a single question. This creates a "council of advisors" approach where Claude can synthesize multiple viewpoints alongside its own to provide more comprehensive answers.

Features

• Query multiple Ollama models with a single question
• Assign different roles/personas to each model
• View all available Ollama models on your system
• Customize system prompts for each model
• Configure via environment variables
• Integrate seamlessly with Claude for Desktop

Prerequisites

• Node.js 16.x or higher
• Ollama installed and running (see Ollama installation)
• Claude for Desktop (for the complete advisory experience)

Installation

1. Clone this repository:

   git clone https://github.com/yourusername/multi-model-advisor.git
   cd multi-model-advisor
   

2. Install dependencies:

   npm install
   

3. Build the project:

   npm run build
   

4. Install required Ollama models:

   ollama pull gemma3:1b
   ollama pull llama3.2:1b
   ollama pull deepseek-r1:1.5b
   

Configuration

Create a .env file in the project root with your desired configuration:

# Server configuration
SERVER_NAME=multi-model-advisor
SERVER_VERSION=1.0.0
DEBUG=true

# Ollama configuration
OLLAMA_API_URL=http://localhost:11434
DEFAULT_MODELS=gemma3:1b,llama3.2:1b,deepseek-r1:1.5b

# System prompts for each model
GEMMA_SYSTEM_PROMPT=You are a supportive and empathetic AI assistant focused on human well-being. Provide considerate and balanced advice.
LLAMA_SYSTEM_PROMPT=You are a logical and analytical AI assistant. Think step-by-step and explain your reasoning clearly.
DEEPSEEK_SYSTEM_PROMPT=You are a creative and innovative AI assistant. Think outside the box and offer novel perspectives.

Connect to Claude for Desktop

1. Locate your Claude for Desktop configuration file:

   • MacOS: ~/Library/Application Support/Claude/claude_desktop_config.json
   • Windows: %APPDATA%\Claude\claude_desktop_config.json

2. Edit the file to add the Multi-Model Advisor MCP server:

{
  "mcpServers": {
    "multi-model-advisor": {
      "command": "node",
      "args": ["/absolute/path/to/multi-model-advisor/build/index.js"]
    }
  }
}

3. Replace /absolute/path/to/ with the actual path to your project directory

4. Restart Claude for Desktop

Usage

Once connected to Claude for Desktop, you can use the Multi-Model Advisor in several ways:

List Available Models

You can see all available models on your system:

Show me which Ollama models are available on my system

This will display all installed Ollama models and indicate which ones are configured as defaults.

Basic Usage

Simply ask Claude to use the multi-model advisor:

what are the most important skills for success in today's job market, 
you can use gemma3:1b, llama3.2:1b, deepseek-r1:1.5b to help you 

Claude will query all default models and provide a synthesized response based on their different perspectives.

How It Works

1. The MCP server exposes two tools:

   • list-available-models: Shows all Ollama models on your system
   • query-models: Queries multiple models with a question

2. When you ask Claude a question referring to the multi-model advisor:

   • Claude decides to use the query-models tool
   • The server sends your question to multiple Ollama models
   • Each model responds with its perspective
   • Claude receives all responses and synthesizes a comprehensive answer

3. Each model can have a different "persona" or role assigned, encouraging diverse perspectives.

Troubleshooting

Ollama Connection Issues

If the server can't connect to Ollama:

• Ensure Ollama is running (ollama serve)
• Check that the OLLAMA_API_URL is correct in your .env file
• Try accessing http://localhost:11434 in your browser to verify Ollama is responding

Model Not Found

If a model is reported as unavailable:

• Check that you've pulled the model using ollama pull <model-name>
• Verify the exact model name using ollama list
• Use the list-available-models tool to see all available models

Claude Not Showing MCP Tools

If the tools don't appear in Claude:

• Ensure you've restarted Claude after updating the configuration
• Check the absolute path in claude_desktop_config.json is correct
• Look at Claude's logs for error messages
