The stream is stuck when trigger stop/ abort during tool call #1614

Describe the bug
I'm using AI chat agent in my project and trying to let user cancel/ abort the response from agent.

I tried these both ways:

• Use stop() in useAgentChat hook
• Make a callable in agent for triggering abortAllRequests()

Both works well when there is no tool call happening, the isStreaming flag turns false immediately.
But if there is tool call running, the isStreaming is stuck at true

In my case, the tools are provided by MCP server

To Reproduce
Steps to reproduce the behavior:

1. Chat with Agent
2. Wait till it's running tool
3. Trigger stop/ abort but isStreaming does not turn false

Expected behavior
The isStreaming always turns false when trigger stop/ abort.
