add-label · Todoist MCP: Risk & Policy

WHAT IT DOES

What add-label does on Todoist MCP

AI agents use add-label to create or update resources in Todoist MCP — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Todoist MCP environment.

WHY IT NEEDS A POLICY

Why add-label needs a policy

Adding a label is a write operation that modifies task properties in a reversible manner. It does not delete data (not Destructive), execute arbitrary code (not Execute), involve financial transactions (not Financial), or retrieve data without side effects (not Read). The impact is localized to task labeling and easily undone by removing the label, making it low severity.

From the tool's definition Tool name 'add-label' and description 'Add a label to a task in Todoist' indicate creating or modifying task metadata. This is a reversible operation that adds a label association to an existing task.

Verdict

add-label Rate-limited

add-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.
