View all permission overwrites on a channel, showing which roles/users have specific allows and denies.
AI agents call view_channel_permissions to retrieve information from Discord without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and displays permission configuration data without side effects. It retrieves information about channel access control settings, which is a read operation. No data is modified, deleted, or executed. The blast radius of misuse is minimal—an unauthorized user could only learn about existing permissions, not alter them.

PolicyLayer is an MCP gateway — it sits between your AI agents and Discord, and nothing reaches the server without passing your rules. This is the rule we recommend for view_channel_permissions:
{
"version": "1",
"default": "deny",
"tools": {
"view_channel_permissions": {}
}
}view_channel_permissions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

View all permission overwrites on a channel, showing which roles/users have specific allows and denies. It is categorised as a Read tool in the Discord MCP Server, which means it retrieves data without modifying state.
Register the Discord MCP server in PolicyLayer and add a rule for view_channel_permissions: 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 Discord. Nothing to install.
view_channel_permissions is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the view_channel_permissions 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 view_channel_permissions. 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.
view_channel_permissions is provided by the Discord MCP server (hardheadhackerhead/discord-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Discord, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
