Which integrations are available for this server?

Used for cloning the repository as part of the installation process. Hosts the repository at github.com/WaiYanNyeinNaing/mcp-dummy-server and the FastMCP framework at github.com/jlowin/fastmcp. Required for running the MCP server with version 3.10+ specifically needed for FastMCP compatibility.

How do I use FastMCP Dummy Server?

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., "@FastMCP Dummy Server multiply 14 by 11 to get the area of my room" 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.

Simple MCP Server

Author: Dr. Wai Yan Nyein Naing

A simple example of an MCP server for beginners.

Quick Start

1. Install

# Clone the repository git clone https://github.com/WaiYanNyeinNaing/mcp-dummy-server.git cd mcp-dummy-server # Create virtual environment python3.10 -m venv .venv source .venv/bin/activate # Install dependencies pip install -r requirements.txt

2. Test

Option 1: Start server first (recommended for learning)

# Terminal 1: Start the server python server.py # Terminal 2: Run the client python client.py

Option 2: Auto-start (client starts server automatically)

# Client automatically starts the server python client.py

Example: Reasoning Calculation with LLM + MCP Tool

Suppose you ask an LLM:

"You're buying carpet for a rectangular room that's 14 feet by 11 feet. The carpet costs $4.25 per square foot. How much will the carpet cost, and if there's a 7.5% sales tax, what's your total cost?"

How the LLM solves it with MCP tools:

Calls the multiply tool to compute the area: 14 × 11 = 154
Calls the multiply tool to get the carpet cost: 154 × 4.25 = 654.50
Calls the percentage tool to get the sales tax: 7.5% of 654.50 = 49.09
Calls the add tool to get the total: 654.50 + 49.09 = 703.59

Final answer:

Carpet cost (before tax): $654.50 Sales tax: $49.09 Total cost: $703.59

Benefit:

By leveraging the MCP server's calculation tools, LLMs can solve real-world math and reasoning problems accurately, even for decimal and multi-step questions.
