Copilot Studio MCP Server

This is an example MCP server that can be used with Microsoft Copilot Studio.
It uses Python and the official MCP Python SDK, and provides the following two tools:

• echo: Repeats the input sentence 3 times

• multi: Squares the input number

Technical Standards

• Language: Python

• SDK: mcp[cli]

• Transport: Streamable HTTP

• Recommended execution configuration: stateless_http=True, json_response=True

Requirements

• Python 3.10 or higher

• Generative orchestration must be enabled to use MCP in Copilot Studio

Installation

Using uv

uv sync

Using pip

pip install "mcp[cli]>=1.9.0"

Execution

python server.py

The server runs using the MCP Streamable HTTP method.
The default path generally uses /mcp.

PowerShell Quick Start

You can run it with the script below in the project folder.

.\start_mcp_server.ps1

Use the script below to stop it.

.\stop_mcp_server.ps1

If .ps1 execution is blocked due to PowerShell execution policies, use the .cmd file below.

.\start_mcp_server.cmd
.\stop_mcp_server.cmd

start_mcp_server.cmd opens a new PowerShell window to run the server, so the MCP server remains active as long as that window is open.
