Why bb_search_repositories needs a policy

This tool retrieves information about repositories through a search query. It is a read-only operation that does not create, modify, delete, or execute anything. No AI agent misuse of a search function would cause irreversible damage or harmful side effects. Severity is low because the blast radius is minimal—search results contain only existing metadata that the authenticated user is authorized to access.

From the tool's definition Tool name 'bb_search_repositories' and description 'Search repositories in Bitbucket' indicate a query/retrieval operation with no side effects. Search operations retrieve data without modifying, deleting, or executing code.

POLICY

How to control bb_search_repositories

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_search_repositories:

policy.json

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

bb_search_repositories 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 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.
