WHAT IT DOES

What list_object_schemas does on Sanka MCP Server

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

RISK

Why list_object_schemas is rated Low

This tool queries and returns schema information about custom objects in Sanka. It is a read-only operation that retrieves metadata without creating, modifying, deleting, or executing any actions. The note about integration schema listing being a V2 backend gap indicates this is purely informational. No blast radius from misuse — an agent listing schemas cannot cause harm.

From the tool's definition Tool name is 'list_object_schemas' and description states 'List Sanka custom object schemas' — a retrieval operation with no modification or side effects.
