Search for server members by name, username, or nickname. Returns matching members with relevance.
AI agents call search_members 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 member data and returns results without creating, modifying, deleting, or executing any actions. It is a standard read operation similar to a search or lookup function. The low severity reflects that access to member information carries minimal risk compared to administrative actions like role assignment, banning, or message deletion that appear in sibling tools.
From the tool's definition Tool description states 'Search for server members by name, username, or nickname. Returns matching members with relevance.' This is a retrieval operation with no modification of data or side effects.
Documented attack patterns abuse exactly the kind of access search_members 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 search_members:
{
"version": "1",
"default": "deny",
"tools": {
"search_members": {}
}
}search_members is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for server members by name, username, or nickname. Returns matching members with relevance. 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 search_members: 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.
search_members 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 search_members 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 search_members. 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.
search_members 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.
Free to start. No card required.
