THE RISK

Critical Risk

Why bb_delete_file needs a policy

File deletion is irreversible and destructive. Once deleted from a repository, recovering the file requires manual restoration from backups or version history, making this a destructive operation with potentially significant impact on codebase integrity. The high severity reflects that accidental or malicious file deletion could corrupt repository state and workflow.

From the tool's definition Tool name: bb_delete_file. Description: Delete a file from a Bitbucket repository. The verb 'delete' indicates an irreversible action that cannot be undone.

POLICY

How to control bb_delete_file

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Bitbucket Python, and nothing reaches the server without passing your rules. This is the rule we recommend for bb_delete_file:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "bb_delete_file"
  ]
}

bb_delete_file disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register MCP Bitbucket Python — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about bb_delete_file

What does the bb_delete_file tool do? +

Delete a file from a Bitbucket repository. It is categorised as a Destructive tool in the MCP Bitbucket Python MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.

How do I enforce a policy on bb_delete_file? +

Register the MCP Bitbucket Python MCP server in PolicyLayer and add a rule for bb_delete_file: 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 MCP Bitbucket Python. Nothing to install.

What risk level is bb_delete_file? +

bb_delete_file is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit bb_delete_file? +

Yes. Add a rate_limit block to the bb_delete_file 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.

How do I block bb_delete_file completely? +

Set action: deny in the PolicyLayer policy for bb_delete_file. 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.

What MCP server provides bb_delete_file? +

bb_delete_file is provided by the MCP Bitbucket Python MCP server (kallows/mcp-bitbucket). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every MCP Bitbucket Python tool call.

Start from MCP Bitbucket Python, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
