Terminal 2:

dapr run --app-id daprmcp --resources-path components -- go run cmd/daprmcp/main.go --http localhost:8080

Terminal 3:

Terminal 4:

curl -i -X POST http://localhost:8001/run -H "Content-Type: application/json" -d '{"task": "Only save this message in a state with a random key. Do nothing else. Message: Hello Steve!"}'

NB: Currently the instructions and details could use improvements. Same can be said for Steve's instructions. This is purely for demo purpose.
