WHAT IT DOES

What bb_comment_issue does on Bitbucket Cloud MCP Server

AI agents use bb_comment_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_comment_issue needs a policy

Adding a comment creates new data in the issue tracking system but is reversible (comments can be edited or deleted). This does not retrieve data (Read), execute arbitrary code (Execute), permanently delete data (Destructive), or move money (Financial). It is a standard write operation that modifies issue state by appending a comment, consistent with the Write category for create/update operations.

From the tool's definition Tool name 'bb_comment_issue' and description 'Add a comment to an issue' indicate creation of new comment data. The verb 'Add' and action of commenting represent reversible modification of issue state.
