Get a table by fully qualified table name.
AI agents call get_table_by_fqn to retrieve information from Mcp Openmetadata without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves table metadata by identifier without any side effects, data modification, or external operations. It is a straightforward read-only query operation analogous to a database SELECT or API GET request.
From the tool's definition Tool name 'get_table_by_fqn' and description 'Get a table by fully qualified table name' indicate a retrieval operation. The server description confirms this retrieves metadata from OpenMetadata with no modification capability mentioned.
