What schedule_campaign does on Mailchimp MCP
AI agents invoke schedule_campaign to trigger actions in Mailchimp MCP. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.
Why schedule_campaign is rated High
Scheduling a campaign in Mailchimp triggers an external operation — it queues an email campaign for delivery to potentially large audiences. This is an Execute-category action (triggering an external operation). The description is empty, so confidence is reduced, but the name strongly implies scheduling/triggering a send action. Misuse could result in mass emails being sent to subscriber lists, hence high severity.
From the tool's definition Tool name 'schedule_campaign' on a Mailchimp MCP server; description is empty and uninformative.
Attacks that exploit this kind of access
The rule that runs schedule_campaign safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Mailchimp MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For schedule_campaign, this is the rule to start with:
schedule_campaign stays usable, but rate-capped: a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect Mailchimp MCP, apply this rule, and every schedule_campaign call is checked against it from then on.
