THE RISK

Low Risk

Why getRepositoryBranchingModel needs a policy

This tool retrieves configuration information about a repository's branching model. 'Get' operations are read-only queries that do not create, modify, delete, or execute anything. The branching model is metadata about repository structure. Misuse carries minimal risk since it only exposes existing configuration data without enabling destructive or financial actions.

From the tool's definition Tool name 'getRepositoryBranchingModel' and description 'Get the branching model for a repository' indicate data retrieval with no modification or side effects.

POLICY

How to control getRepositoryBranchingModel

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "getRepositoryBranchingModel": {}
  }
}

getRepositoryBranchingModel is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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