WHAT IT DOES

What gitlab_create_ci_variable does on Gitlab

AI agents use gitlab_create_ci_variable to create or update resources in Gitlab, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Gitlab environment.

RISK

Why gitlab_create_ci_variable is rated Medium

Creating CI variables is a Write operation—it creates new configuration data that persists and affects pipeline behavior. However, severity is 'high' rather than 'medium' because CI variables frequently store sensitive credentials (API keys, tokens, passwords); an agent could maliciously inject secrets or misconfigure deployments.

From the tool's definition Tool name 'gitlab_create_ci_variable' indicates creation of CI/CD variables in GitLab. CI variables are configuration data that can include secrets, credentials, and environment-specific values.

RECOMMENDED RULE

The rule that runs gitlab_create_ci_variable safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Gitlab, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For gitlab_create_ci_variable, this is the rule to start with:

gitlab_create_ci_variable Rate-limited

gitlab_create_ci_variable stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

The button opens the PolicyLayer dashboard: create your workspace, connect Gitlab, apply this rule, and every gitlab_create_ci_variable call is checked against it from then on.
