# 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)

uv run main.py

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-mcp
