Description
Quite often after invoking the IDA pro MCP, it says:
```
Execution failed: TypeError: Do not know how to serialize a BigInt
```
The agent then immediately stops. My work around is to just say continue, but it would be nice if it did that without my input.

Research direction
The report points to the /chat flow and the IDA Pro MCP integration, but names no files or tests. Start by reproducing the BigInt serialization failure on Windows with app version 1.1.2, then trace how the failed MCP result is handled. Done means this error no longer stops the agent or requires the user to say “continue”.
