WHAT IT DOES

What update_short_link does on instantKOM MCP Server

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

RISK

Why update_short_link is rated Medium

Updating a short link is a Write operation: it modifies data but is not destructive (can be reverted), not financial, and does not execute arbitrary code. Severity is medium because misconfigured short links could redirect users to malicious sites or disrupt communications, but the blast radius depends on the link's usage context within the instantKOM platform.

From the tool's definition Tool name and description: 'Update an existing short link' — modifies existing data (the short link configuration) reversibly.

update_short_link 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.
