Destructive tools (delete_ci_variable, delete_group, delete_pipeline_trigger) permanently delete resources. There is no undo. An agent calling these in a retry loop causes irreversible damage.
Write operations (create_ci_variable, create_group, create_pipeline_trigger) modify state. Without rate limits, an agent can make hundreds of changes in seconds — faster than any human can review or revert.

Yes. The GitLab Operations server exposes 6 destructive tools including delete_ci_variable, delete_group, delete_pipeline_trigger. These permanently remove resources with no undo. PolicyLayer blocks destructive tools by default so they never reach the upstream server.
The GitLab Operations server has 9 write tools including create_ci_variable, create_group, create_pipeline_trigger. Set a rate limit in your policy -- for example, 10 calls per hour prevents an agent from making more than 10 modifications per hour. PolicyLayer enforces this at the gateway, before calls reach GitLab Operations.
22 tools across 3 categories: Destructive, Read, Write. 7 are read-only. 15 can modify, create, or delete data.
Register the GitLab Operations MCP server in PolicyLayer, apply the suggested rules above (adjust the limits to your use case), and point your AI client at the PolicyLayer proxy URL instead of the server directly. Your agents keep the same tools; PolicyLayer evaluates every call against policy before it executes. Nothing to install, live in minutes.
Starter policies for each. Same risk classification, live on your fleet in minutes.
