Delete a branch from a Bitbucket repository (destructive action, requires confirmation)
AI agents call bb_delete_branch to permanently remove resources in Bitbucket Cloud MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Branch deletion is irreversible and can cause loss of code history and commits. While the tool includes a confirmation requirement (a safety control), the underlying action permanently removes a branch from the repository. This is a destructive operation that cannot be undone without access to git reflog or repository backups.
From the tool's definition Tool name 'bb_delete_branch' combined with description 'Delete a branch from a Bitbucket repository (destructive action, requires confirmation)' explicitly states this is a destructive action.

Register the Bitbucket Cloud MCP Server MCP server in PolicyLayer and add a rule for bb_delete_branch: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Bitbucket Cloud MCP Server. Nothing to install.
bb_delete_branch is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the bb_delete_branch rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for bb_delete_branch. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
bb_delete_branch is provided by the Bitbucket Cloud MCP Server MCP server (or2ooo/bitbucket-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
