WHAT IT DOES

What bb_create_issue does on Bitbucket Cloud MCP Server

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

WHY IT NEEDS A POLICY

Why bb_create_issue needs a policy

Creating an issue is a Write operation: it adds new data to the repository but is fully reversible (the issue can be deleted or closed). It has low severity because issue creation alone does not modify code, delete data, execute operations, or commit financial obligations. The blast radius is minimal—an incorrectly created issue causes minor disruption and can be easily remediated.

From the tool's definition Tool name includes 'create' and description states 'Create a new issue in a Bitbucket repository', which creates data reversibly in the issue tracking system.
