MCP Elicitations Demo Server

MCP Elicitations Demo Server

A demonstration server that showcases elicitations across different Model Context Protocol (MCP) use cases. This server demonstrates how to collect user input dynamically using the MCP elicitation system.

What are Elicitations?

Elicitations allow MCP servers to request structured input from users during tool execution, enabling interactive and dynamic workflows.

Available MCP Components

Tools

• greeting - Simple greeting tool that asks for your name
• contact-info - Collects structured contact information (name, email, age)

Resources

• config://user - User greeting resource that dynamically requests your name

Prompts

• greeting-prompt - Generates a personalized greeting prompt based on your name

How It Works

Each component demonstrates elicitations in different contexts:

1. Tools show how to collect input during tool execution
2. Resources demonstrate dynamic content generation based on user input
3. Prompts showcase how to create personalized prompts using elicited data

Running the Server

npm install
npm run build
npm start

The server will run on http://localhost:3000

Example Elicitation Schemas

Simple Name Request

{
  "type": "object",
  "properties": {
    "name": {
      "type": "string",
      "description": "The name of the user"
    }
  },
  "required": ["name"]
}

Contact Information Request

{
  "type": "object",
  "properties": {
    "name": {
      "type": "string",
      "description": "Your full name"
    },
    "email": {
      "type": "string",
      "format": "email", 
      "description": "Your email address"
    },
    "age": {
      "type": "number",
      "minimum": 18,
      "description": "Your age"
    }
  },
  "required": ["name", "email"]
}

This demo showcases MCP elicitations for creating interactive, user-driven experiences across tools, resources, and prompts.
