WHAT IT DOES

What batch_create_versions does on MCP Atlassian + Bitbucket

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

WHY IT NEEDS A POLICY

Why batch_create_versions needs a policy

The tool creates or initializes new versions (probably release versions, project versions, or similar artifacts in Jira/Bitbucket). This is reversible (versions can be deleted or modified), making it Write rather than Destructive. The batch nature and lack of detail about what 'versions' entails prevents high confidence.

From the tool's definition Tool name 'batch_create_versions' indicates creation of multiple version objects, likely in Jira or Bitbucket. The 'batch' prefix and 'create' verb suggest bulk Write operations. Description is empty, which reduces confidence.
