Delete a token from a folder or program in Marketo.
AI agents call delete_token to permanently remove resources in Marketo MCP Server — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Deletion is irreversible and removes configured assets from the marketing automation system. This prevents recovery without manual restoration. The severity is high (not critical) because token deletion affects campaign configuration but is typically limited in scope to that specific token, unlike broader destructive operations that could affect multiple programs or lead data.
From the tool's definition Tool name 'delete_token' explicitly performs deletion. Description confirms irreversible action: 'Delete a token from a folder or program in Marketo.' Tokens are configuration assets used in Marketo programs and campaigns.
Attacks that exploit this kind of access
Delete a token from a folder or program in Marketo. It is categorised as a Destructive tool in the Marketo MCP Server MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Marketo MCP Server MCP server in PolicyLayer and add a rule for delete_token: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Marketo MCP Server. Nothing to install.
delete_token is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the delete_token rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for delete_token. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
delete_token is provided by the Marketo MCP Server MCP server (tyron-pretorius/marketo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
