Implementation Reference
- src/mcp_server_foundry/server.py:67-95 (handler)The main handler function for the 'query_ontology_type' tool. It uses the FoundryClient to search for objects in the specified ontology type based on the 'where' filter, dynamically determining properties to select. The function parameters include Pydantic Field descriptions serving as input schema.
