Giles Odigwe 93cbf6b3f0 Python: Parse MCP CallToolResult.structuredContent field to prevent tool results returning None (#6421)
* Parse structuredContent from MCP CallToolResult (#3313)

The _parse_tool_result_from_mcp method only iterated over the content
field from CallToolResult, ignoring the structuredContent field entirely.
MCP servers that return JSON data via structuredContent (e.g., Power BI
MCP) appeared to return None.

Add handling for structuredContent: when present, serialize it as JSON
text and append it to the result list. This preserves the data for the
LLM while maintaining backward compatibility with existing behavior.

* Python: Parse MCP CallToolResult.structuredContent field to prevent tool results returning None

Fixes #3313

* Address review feedback: add default=str to json.dumps and remove .checkpoints/

- Add default=str to json.dumps for structuredContent serialization so
  non-JSON-serializable values (e.g. bytes) degrade gracefully instead
  of raising TypeError
- Remove all .checkpoints/ runtime artifacts from the repository
- Add **/.checkpoints/ to .gitignore to prevent future accidental commits
- Add test for non-serializable structuredContent values

Fixes #3313

* Address review feedback for #3313: Python: MCP CallToolResult.structuredContent field is not parsed, causing tool results to return None
