Output Parsers for mcptools

Generate output parsers for Python tools in the mcptools package that have unstructured return types.

Identifying Unstructured Return Types

A tool has an unstructured return type when its run() function returns:

• A str directly
• A Result model with a single str field (named result, content, output, etc.) plus only model_config

A Result model with multiple fields (beyond model_config) has a structured return type and does not need a parser.

Workflow

1. Test the Python tool

Run the Python tool with ipybox_execute_ipython_cell tool using 2-3 example inputs to observe return value patterns:
