WHAT IT DOES

What update_widget does on instantKOM MCP Server

AI agents use update_widget 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_widget is rated Medium

The tool modifies existing dashboard/widget resources reversibly without deleting data or executing arbitrary code. This fits the Write category (creates or modifies data reversibly). Severity is medium because widget updates could affect user interface display, messaging flows, or analytics dashboards, but the impact is scoped to widget configuration rather than core platform operations or data deletion.

From the tool's definition Tool name 'update_widget' with description 'Update an existing widget' indicates modification of existing data. Context shows this is part of a messenger platform management system where widgets are likely UI components or dashboard elements.

RECOMMENDED RULE

The rule that runs update_widget safely

update_widget Rate-limited

update_widget 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.
