What cancel_campaign does on Sequenzy Mcp
AI agents call cancel_campaign to permanently remove resources in Sequenzy Mcp, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Why cancel_campaign is rated Critical
cancel_campaign irreversibly terminates an active campaign, preventing further email sends and eliminating the ability to resume it. While not deleting data directly, it destroys the campaign's operational state in a way that cannot be reversed.

From the tool's definition Tool description states: 'Stops scheduled and sending campaigns', 'Remaining emails will not be sent and the campaign cannot be restarted - this cannot be undone.' The phrase 'cannot be undone' and the irreversible nature of halting a campaign workflow…

The rule that runs cancel_campaign safely
PolicyLayer is an MCP gateway: it sits between your AI agents and Sequenzy Mcp, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For cancel_campaign, this is the rule to start with:
cancel_campaign 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 Sequenzy Mcp, apply this rule, and every cancel_campaign call is checked against it from then on.
