AI agents call list-all-tools to retrieve information from MCP Hub MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and returns information about available tools across connected MCP servers. It performs a read-only operation that retrieves metadata without creating, modifying, deleting, or executing any actions. The advisory note to use 'find-tools' for better performance further confirms this is a passive discovery/query tool.
From the tool's definition Tool name 'list-all-tools' and description 'List ALL available tools from all connected servers' indicate data retrieval with no side effects.
Risk signalsBulk/mass operation — affects multiple targets
Documented attack patterns abuse exactly the kind of access list-all-tools gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Hub MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list-all-tools:
{
"version": "1",
"default": "deny",
"tools": {
"list-all-tools": {}
}
}list-all-tools is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

It is categorised as a Read tool in the MCP Hub MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MCP Hub MCP Server MCP server in PolicyLayer and add a rule for list-all-tools: 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 MCP Hub MCP Server. Nothing to install.
list-all-tools 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 list-all-tools 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 list-all-tools. 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.
list-all-tools is provided by the MCP Hub MCP Server MCP server (warpdev/mcp-hub-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
