Manage Kit email broadcasts — list with status filter, get details, create drafts or scheduled sends, update, delete, view performance stats, compare stats across all broadcasts, or analyze per-link click data. Actions: list, get, create, update, delete, stats, list_stats, get_clicks
AI agents use manage_broadcasts to create or update resources in Kit — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Kit environment.
While the tool supports destructive actions (delete), the primary purpose is managing broadcasts through reversible write operations (create drafts, update scheduling). Email broadcasts, once deleted, cannot be fully recovered from a user perspective, but the focus of the tool appears to be creation and modification.
From the tool's definition The tool description explicitly lists actions: 'create drafts or scheduled sends, update, delete' and includes 'list, get, create, update, delete, stats, list_stats, get_clicks'.
Attacks that exploit this kind of access
Manage Kit email broadcasts — list with status filter, get details, create drafts or scheduled sends, update, delete, view performance stats, compare stats across all broadcasts, or analyze per-link click data. Actions: list, get, create, update, delete, stats, list_stats, get_clicks. It is categorised as a Write tool in the Kit MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Kit MCP server in PolicyLayer and add a rule for manage_broadcasts: 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 Kit. Nothing to install.
manage_broadcasts is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the manage_broadcasts 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 manage_broadcasts. 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.
manage_broadcasts is provided by the Kit MCP server (@dancumberland/kit-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
