WHAT IT DOES

What update_workflow does on Sanka MCP Server

AI agents use update_workflow 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_workflow is rated Medium

The tool modifies workflow definitions in Sanka or external providers (HubSpot), which affects business process automation. While updates are theoretically reversible (unlike deletion), incorrect workflow modifications could disrupt critical business processes, trigger unintended automations, or affect downstream operations.

From the tool's definition Tool performs 'Update' operation on workflow definitions, explicitly stated as 'Update a Sanka workflow definition or a provider workflow'. Updates are reversible modifications that change system state.

RECOMMENDED RULE

update_workflow Rate-limited

update_workflow 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.
