Click on "Install Server".
Wait a few minutes for the server to deploy. Once ready, it will show a "Started" state.
In the chat, type
@followed by the MCP server name and your instructions, e.g., "@simple_mcpGenerate a random float between 0 and 1."
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 (Python)
This project provides a minimal Model Context Protocol (MCP) server using Python. It exposes a single tool random_float that returns a random float in [0,1). The server supports multiple transport modes: STDIO (default), HTTP, and SSE.
Run locally
Default (STDIO transport)

Server Environment Variables
Variable | Purpose | Default |
APP_TRANSPORT | Transport type (STDIO, HTTP, SSE) | STDIO |
APP_HOST | Server host | 0.0.0.0 |
APP_PORT | Server port | 8000 |
Docker
Build the image and run:
docker build -t simple-mcp .Docker with different transports
# HTTP transport
docker run --rm -p 8000:8000 -e APP_TRANSPORT=HTTP simple-mcp
# SSE transport
docker run --rm -p 8000:8000 -e APP_TRANSPORT=SSE simple-mcp
# Custom port
docker run --rm -p 9000:9000 -e APP_TRANSPORT=HTTP -e APP_PORT=9000 simple-mcpTest as a standalone app
