What gitlab_revoke_personal_access_token does on Gitlab
AI agents call gitlab_revoke_personal_access_token to permanently remove resources in Gitlab, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why gitlab_revoke_personal_access_token is rated Critical
Revoking a personal access token destroys the token's validity permanently. This is a destructive operation because the token cannot be recovered once revoked—a new token must be created. While not data deletion in the traditional sense, credential revocation is irreversible and has significant blast radius if triggered unintentionally (service outages, broken integrations, disrupted CI/CD pipelines).
From the tool's definition Tool name 'gitlab_revoke_personal_access_token' indicates permanent revocation of authentication credentials. Revocation is an irreversible action that cannot be undone without manual intervention.
Attacks that exploit this kind of access
The rule that runs gitlab_revoke_personal_access_token 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_revoke_personal_access_token, this is the rule to start with:
gitlab_revoke_personal_access_token is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
The button opens the PolicyLayer dashboard: create your workspace, connect Gitlab, apply this rule, and every gitlab_revoke_personal_access_token call is checked against it from then on.
