WHAT IT DOES

What update_task does on Motion MCP Server

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

WHY IT NEEDS A POLICY

Why update_task needs a policy

This tool modifies task data in the Motion workspace but does not delete or permanently remove information. Updates are typically reversible (data can be changed again), making it a Write action rather than Destructive. Medium severity reflects that misuse could corrupt or alter important project/task data, but changes can generally be undone or corrected.

From the tool's definition Tool name 'update_task' and description 'Update an existing task in Motion' indicate modification of existing data in a reversible manner.

update_task Rate-limited

update_task 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.
