A minimal MCP client demonstrating polling for task results over streamable HTTP.

First, start the simple-task server in another terminal:

cd examples/servers/simple-task
uv run mcp-simple-task

Then run the client:

cd examples/clients/simple-task-client
uv run mcp-simple-task-client

Use --url to connect to a different server.

1. Connects to the server via streamable HTTP
2. Calls the long_running_task tool as a task
3. Polls the task status until completion
4. Retrieves and prints the result

Available tools: ['long_running_task']

Calling tool as a task...
Task created: <task-id>
  Status: working - Starting work...
  Status: working - Processing step 1...
  Status: working - Processing step 2...
  Status: completed -

Result: Task completed!
