WHAT IT DOES

What update_work_item does on Plane

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

RISK

Why update_work_item is rated Medium

Updates are reversible modifications to data (Write category) rather than irreversible deletions (Destructive) or code execution (Execute). Medium severity reflects typical project management blast radius—unauthorized updates could corrupt work item state, assignments, or metadata, but are recoverable. Confidence slightly reduced due to missing tool-specific description.

From the tool's definition Tool name 'update_work_item' indicates modification of existing work items. Server description confirms 'full CRUD operations for issues' including updates.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs update_work_item safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Plane, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For update_work_item, this is the rule to start with:

update_work_item Rate-limited

update_work_item 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.
