resolves #3938

What is in this change?

This pull request fixes a bug where Anthropic agents would crash when calling MCP server endpoints that have nested parameters in their input_schema. With this change, the agent now correctly handles nested input parameters and does not crash. The logic for parsing input_schema was updated to support nested objects.

Additional Information

Tested locally on both flat and nested parameter endpoints. No changes were made to output schema handling. Lint and Docker build pass.
