How do I use MCP BMI Server Template?

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., "@MCP BMI Server Template calculate my BMI for 70kg and 175cm" 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.

MCP BMI Server Template (FastAPI + SSE)

A minimal Model Context Protocol (MCP) server exposing a single tool: bmiCalculator.

Discovery endpoint (SSE): GET /mcp
Invocation endpoint: POST /invoke
Health check: GET /healthz

Quick Start (local)

pip install -r requirements.txt export API_KEY=changeme # optional uvicorn main:app --host 0.0.0.0 --port 10000

Test:

# Discover tools (SSE) curl -N -H "Accept: text/event-stream" -H "x-api-key: changeme" http://localhost:10000/mcp # Invoke tool curl -X POST http://localhost:10000/invoke \ -H "Content-Type: application/json" \ -H "x-api-key: changeme" \ -d '{"tool":"bmiCalculator","params":{"weight":70,"height":175,"unit":"cm"}}'

Docker

docker build -t mcp-bmi . docker run -p 10000:10000 -e API_KEY=changeme mcp-bmi

Deploy to Render (example)

Create a new Web Service from this repo
Set environment variable API_KEY (optional but recommended)
The service will start with the Dockerfile

Your base URL will look like:

https://<your-service>.onrender.com

Use the MCP SSE endpoint:

https://<your-service>.onrender.com/mcp

MCP Host config example

{ "mcpServers": { "bmiAgent": { "url": "https://<your-service>.onrender.com/mcp", "headers": { "x-api-key": "changeme" } } } }

Notes

SSE (text/event-stream) is used for discovery. If your host requires WebSocket, add a /ws endpoint.
Extend by adding more tools in MCPHello.tools and dispatching in /invoke.
