What update_item does on Sanka MCP Server
AI agents use update_item 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.
Why update_item is rated Medium
This tool creates or modifies data in a reversible manner, fitting the Write category. Severity is high because Sanka appears to be a business operations platform (based on sibling tools managing invoices, orders, payroll, and approvals), so uncontrolled item updates could corrupt critical business records. However, it's not Financial (no money movement) or Destructive (changes are reversible).
From the tool's definition Tool name 'update_item' and description 'Update an existing item in Sanka' indicate modification of existing data.
Attacks that exploit this kind of access
The rule that runs update_item safely

update_item 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.
The button opens the PolicyLayer dashboard: create your workspace, connect Sanka MCP Server, apply this rule, and every update_item call is checked against it from then on.
