FAQ

Questions about execute_announcement_subscription

What does the execute_announcement_subscription tool do? +

Create or remove one exact Discord announcement subscription after a fresh matching full-inventory plan, signed interactive approval, durable target and guild-inventory exclusion, a unique one-shot operation-key reservation, pending content-free records, one non-retried POST or DELETE, strict response validation when available, and exact target-inventory readback. Creation is a record-free no-op when the exact subscription already exists; uncertain outcomes block same-target continuation. It is categorised as a Write tool in the GuildControl MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on execute_announcement_subscription? +

Register the GuildControl MCP server in PolicyLayer and add a rule for execute_announcement_subscription: 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 GuildControl MCP. Nothing to install.

What risk level is execute_announcement_subscription? +

execute_announcement_subscription is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit execute_announcement_subscription? +

How do I block execute_announcement_subscription completely? +
