WHAT IT DOES

What buckets_create does on Vikunja

AI agents use buckets_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 buckets_create is rated Medium

This tool creates a new bucket (a reversible modification to task/project organization). It does not execute code, delete data irreversibly, move money, or retrieve information. Creation of organizational elements in a task manager is a Write-category operation with low severity—misuse would only add unwanted buckets that can be deleted.

From the tool's definition Tool name 'buckets_create' and description 'Create a new kanban bucket' indicate creation of new data in a kanban board structure.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs buckets_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 buckets_create, this is the rule to start with:

buckets_create Rate-limited

buckets_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.
