mcp-first-server

A Model Context Protocol (MCP) server built with the official MCP SDK, available both as a local stdio server (for Claude Desktop) and as a cloud-deployed HTTP server reachable over the network.

Live demo: https://mcp-first-server.onrender.com (note: free-tier hosting, first request after inactivity may take up to ~50s to wake the instance)

Tools

get_quote — returns a random motivational quote.
get_crypto_price — fetches the live USD price of any cryptocurrency (via CoinGecko).

Two ways to run this server

server.js — stdio transport, for local use with Claude Desktop or any MCP client that spawns a local process.
server-http.js — StreamableHTTP transport wrapped in Express, for cloud/network deployment (this is what's running at the live demo URL above). Listens on process.env.PORT.

Local setup

Terminal

npm install
npm start          # runs server.js (stdio)
node server-http.js  # or run the HTTP version locally

Try the live HTTP endpoint

Terminal

curl -X POST https://mcp-first-server.onrender.com/mcp \
  -H "Content-Type: application/json" \
  -H "Accept: application/json, text/event-stream" \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/list"}'
