What create_label does on Todos
AI agents use create_label to create or update resources in Todos, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Todos environment.
Why create_label is rated Medium
Creating a label is a reversible write operation that adds metadata to a task management system. It does not retrieve data (Read), execute arbitrary code (Execute), delete data (Destructive), or move money (Financial). The impact is limited to adding a new categorization/tagging entity, which is low severity since labels are typically non-critical organizational metadata that can be edited or deleted if needed.
From the tool's definition Tool name is 'create_label' and description states 'Create a new label.' This is a data creation operation that modifies the task management system by adding a new label.
Attacks that exploit this kind of access
The rule that runs create_label safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Todos, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For create_label, this is the rule to start with:
create_label 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 Todos, apply this rule, and every create_label call is checked against it from then on.
Questions about create_label
Create a new label. It is categorised as a Write tool in the Todos MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Todos MCP server in PolicyLayer and add a rule for create_label: 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 Todos. Nothing to install.
create_label 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 create_label 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 create_label. 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.
create_label is provided by the Todos MCP server (@hasna/todos). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
