Implementation Reference
- aws_fis_mcp/tools.py:120-151 (handler)The core handler function for the 'list_experiments' tool. It uses boto3 to call fis.list_experiments(), processes the response by extracting key fields and serializing datetimes to ISO format, then returns a formatted JSON string of the experiments list.
