The rule that runs catch_up_messages safely
PolicyLayer is an MCP gateway: it sits between your AI agents and GuildControl MCP, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For catch_up_messages, this is the rule to start with:
catch_up_messages is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect GuildControl MCP, apply this rule, and every catch_up_messages call is checked against it from then on.
Questions about catch_up_messages
Catch up across bounded exact Discord guild channels in one privacy-minimized read. Each selection starts from its caller-retained cursor or explicitly initializes from the newest bounded page. All channels, connector membership, Message Content intent, and complete read permissions are verified before message reads; results are chronological compact previews with honest coverage and safe next cursors. Bot and webhook messages are omitted by default while still advancing coverage. The connector never persists cursors, inbox state, profiles, raw payloads, or message content. It is categorised as a Read tool in the GuildControl MCP MCP Server, which means it retrieves data without modifying state.
