add_worklog · Jira MCP: Risk & Policy

WHAT IT DOES

What add_worklog does on Jira

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

WHY IT NEEDS A POLICY

Why add_worklog needs a policy

This tool creates or appends worklog records to tickets, which is a reversible modification of data. It does not delete, execute code, move financial resources, or trigger external operations. It falls squarely into Write category as it records and potentially modifies time tracking data on a ticket.

From the tool's definition add_worklog adds time tracking information to a Jira ticket. This creates new data (worklog entry) and modifies the ticket's time tracking state. The tool description explicitly states it adds a worklog, which is a create/record action without deletion.

Verdict

add_worklog Rate-limited

add_worklog 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.
