WHAT IT DOES

What labels_create does on Vikunja

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

RISK

Why labels_create is rated Medium

This tool creates a new label, which is a reversible write operation. It modifies the system state by adding data but does not execute arbitrary code, delete data, or involve financial transactions. The severity is medium because creating labels is a normal operation but could clutter the system if misused by an agent without proper constraints.

From the tool's definition Tool name 'labels_create' and description 'Create a new label' clearly indicate this tool creates new data in the Vikunja task manager system.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs labels_create safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Vikunja, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For labels_create, this is the rule to start with:

labels_create Rate-limited

labels_create 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.
