Why gitlab_get_repository_file needs a policy

This tool retrieves file content from a repository, which is a read-only operation. It queries data without creating, modifying, deleting, or executing anything. The severity is low because reading repository files is a standard, non-destructive operation with minimal blast radius even if misused by an AI agent.

From the tool's definition Tool name 'gitlab_get_repository_file' and description 'Get content of a file in a repository' indicate retrieval of file content without modification or side effects.

POLICY

How to control gitlab_get_repository_file

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

policy.json

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

gitlab_get_repository_file 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 GitLab MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
