What projects_create does on Vikunja
AI agents use projects_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.
Why projects_create is rated Medium
Creating a new project is a reversible Write operation that adds data to the system. It does not execute arbitrary code, delete data, or move money. While it modifies the task management system, the action can be undone by deletion. Medium severity is appropriate because misuse could clutter the workspace with unwanted projects, but the impact is containable and reversible.
From the tool's definition Tool description explicitly states 'Create a new project', and the tool name 'projects_create' confirms it creates a new resource (project) in Vikunja task manager.
Attacks that exploit this kind of access
The rule that runs projects_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 projects_create, this is the rule to start with:
projects_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.
The button opens the PolicyLayer dashboard: create your workspace, connect Vikunja, apply this rule, and every projects_create call is checked against it from then on.
