WHAT IT DOES

What get_object_source does on Oracle MCP Server

AI agents call get_object_source to retrieve information from Oracle MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

WHY IT NEEDS A POLICY

Why get_object_source needs a policy

The tool retrieves source code or object definitions from the database without modifying data. While the description is empty, the naming convention and context with other introspective tools (get_related_tables, get_table_indexes) strongly suggest this queries existing objects rather than executing operations.

From the tool's definition Tool name 'get_object_source' suggests retrieval of source code or metadata; context shows this is alongside DDL/DML execution tools and schema inspection tools (get_table_schema, get_database_vendor_info, get_pl_sql_objects).
