Move a task to a different kanban board column. Use to update task status as work progresses: inbox (planned) -> priority (up next) -> in-progress (active) -> reviewing (needs review) -> done (completed).
AI agents use move_task to create or update resources in Nubis — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Nubis environment.
The tool creates or modifies data (task status/board position) in a reversible manner. It does not delete or destroy data (ruling out Destructive), does not execute arbitrary code (ruling out Execute), involves no financial operations (ruling out Financial), and is not merely a read operation (ruling out Read).
From the tool's definition Tool description states it 'Move[s] a task to a different kanban board column' and 'update[s] task status', which modifies task state reversibly within a workflow system.
Attacks that exploit this kind of access
Move a task to a different kanban board column. Use to update task status as work progresses: inbox (planned) -> priority (up next) -> in-progress (active) -> reviewing (needs review) -> done (completed). It is categorised as a Write tool in the Nubis MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Nubis MCP server in PolicyLayer and add a rule for move_task: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Nubis. Nothing to install.
move_task is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the move_task rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for move_task. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
move_task is provided by the Nubis MCP server (@lil2good/nubis-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
