WHAT IT DOES

What gitlab_list_runners does on Gitlab

AI agents call gitlab_list_runners to retrieve information from Gitlab without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why gitlab_list_runners is rated Low

The 'list_' prefix is a common pattern for read-only operations that enumerate resources. Listing GitLab runners retrieves metadata about CI/CD execution resources but does not create, modify, delete, or execute anything. This is a standard Read operation with low blast radius if misused by an agent.

From the tool's definition Tool name 'gitlab_list_runners' indicates a listing operation. The 'list' verb denotes retrieval of information without modification.

RECOMMENDED RULE

The rule that runs gitlab_list_runners 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_list_runners, this is the rule to start with:

gitlab_list_runners Allowed

gitlab_list_runners is read-only, so it stays allowed. 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_list_runners call is checked against it from then on.
