WHAT IT DOES

What discord_pin_message does on Discord

AI agents use discord_pin_message to create or update resources in Discord, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Discord environment.

RISK

Why discord_pin_message is rated Medium

Pinning a message modifies channel state by changing message visibility/prominence, but is reversible (can be unpinned). This is a Write operation—it creates or modifies data without permanent deletion. The confirmation requirement (confirm=true) suggests the system acknowledges this as a state-changing action.

RECOMMENDED RULE

The rule that runs discord_pin_message safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Discord, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For discord_pin_message, this is the rule to start with:

discord_pin_message Rate-limited

discord_pin_message stays usable, but capped: an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
