update_section · Todoist MCP: Risk & Policy

WHAT IT DOES

What update_section does on Todoist

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

WHY IT NEEDS A POLICY

Why update_section needs a policy

The tool modifies a task management section reversibly, which is a Write operation. Changes to task organization can be undone or adjusted. The blast radius is minimal—misuse would affect only organizational metadata within Todoist, not financial data or sensitive external systems. Severity is low because task section modifications are low-impact and reversible.

From the tool's definition Tool name 'update_section' indicates modification of an existing section (not creation, not deletion). Server description confirms this is part of task management (Todoist). No destructive, financial, or code execution capability.

Verdict

update_section Rate-limited

update_section 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.
