AI agents call discord_get_channel to retrieve information from Sage MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves channel metadata from Discord. It performs a read-only query operation without creating, modifying, deleting, or executing any actions. The severity is low because exposure of channel metadata typically carries minimal risk unless the channel contains highly sensitive information, but the tool itself has no destructive or harmful capability.
From the tool's definition Tool name is 'discord_get_channel' and description states 'Get detailed information about a specific channel' — both indicate a retrieval operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access discord_get_channel gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Sage MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for discord_get_channel:
{
"version": "1",
"default": "deny",
"tools": {
"discord_get_channel": {}
}
}discord_get_channel is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get detailed information about a specific channel. It is categorised as a Read tool in the Sage MCP MCP Server, which means it retrieves data without modifying state.
Register the Sage MCP server in PolicyLayer and add a rule for discord_get_channel: 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 Sage MCP. Nothing to install.
discord_get_channel 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 discord_get_channel 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 discord_get_channel. 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.
discord_get_channel is provided by the Sage MCP server (sagemcp/sagemcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
