Create a poll message in a Discord channel. Allows members to vote on a question with multiple options.
AI agents use send_poll 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.
This tool creates a new poll message, which is a reversible modification of channel data. It does not execute arbitrary code, delete data, or move financial resources. While it affects the Discord server state by adding a message, the action is non-destructive and can be managed through normal Discord moderation (message deletion).
From the tool's definition 'Create a poll message in a Discord channel' indicates the tool creates new content (a poll message) in a Discord channel, which is a write operation that modifies the channel's message history.
Documented attack patterns abuse exactly the kind of access send_poll gives an agent:
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 send_poll:
{
"version": "1",
"default": "deny",
"tools": {
"send_poll": {
"limits": [
{
"counter": "send_poll_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}send_poll 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.

Create a poll message in a Discord channel. Allows members to vote on a question with multiple options. It is categorised as a Write tool in the Discord MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Discord MCP server in PolicyLayer and add a rule for send_poll: 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.
send_poll is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the send_poll 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 send_poll. 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.
send_poll 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.
