update_task · Helios-9 MCP Server MCP: Risk & Policy

WHAT IT DOES

What update_task does on Helios-9 MCP Server

AI agents use update_task to create or update resources in Helios-9 MCP Server — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Helios-9 MCP Server environment.

WHY IT NEEDS A POLICY

Why update_task needs a policy

The update_task tool modifies task records reversibly without deleting data or executing arbitrary code. This is a Write operation—data is changed but not destroyed. The severity is medium because task updates in a project management system affect project status and team coordination, but the operation is reversible and confined to task metadata/properties.

From the tool's definition Tool description states 'Update an existing task with new information', which is explicitly a modification operation on existing data.

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.
