  -H 'Content-Type: application/json' \
  -H 'Accept: application/json, text/event-stream' \
  -d '{"jsonrpc":"2.0","id":1,"method":"tools/call","params":{"name":"hello","arguments":{"args":["world"]}}}'

# via mcporter, pointing at the HTTP endpoint
# mcporter.json: {"mcpServers":{"demo":{"baseUrl":"http://127.0.0.1:8080/mcp"}}}
