WHAT IT DOES

What update_property does on Sanka MCP Server

AI agents use update_property to create or update resources in Sanka MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Sanka MCP Server environment.

RISK

Why update_property is rated Medium

This tool modifies existing properties in Sanka or connected CRM systems. It is a Write operation because it creates or modifies data reversibly (property updates can typically be reverted or modified again). The severity is medium because property updates could affect business logic, integrations, or workflows, but are not destructive (data is not deleted), not financial (no money moves), and not code execution.

From the tool's definition Tool name is 'update_property' and description states 'Update an existing custom property' — classic write operation that modifies data reversibly.

RECOMMENDED RULE

update_property Rate-limited

update_property stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
