Delete an access token from the current Storyblok space using the Management API.
AI agents call delete_access_token to permanently remove resources in Storyblok MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deleting an access token is a destructive action that permanently removes authentication credentials. While not a data deletion, it irreversibly removes a resource and could disrupt integrations or access for legitimate users if invoked inappropriately. This is more severe than a Write operation due to its irreversible nature, but less severe than Financial impact. Classified as Destructive per the rules hierarchy.
From the tool's definition The tool name explicitly states 'delete' and the description confirms it 'Delete an access token'. This is an irreversible removal of a credential that cannot be undone without manual intervention.
Documented attack patterns abuse exactly the kind of access delete_access_token gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Storyblok MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for delete_access_token:
{
"version": "1",
"default": "deny",
"hide": [
"delete_access_token"
]
}delete_access_token disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.
