AI agents call my_tool as a supporting operation in FastMCP Multi-Tenancy workflows.
With no description and a generic name, there is insufficient evidence to classify this tool into any specific risk category. The server context (multi-tenancy, Redis session state) does not provide enough signal about this specific tool's behavior. Defaulting to 'Other' with very low confidence.
From the tool's definition Tool name is 'my_tool' with an empty description. No functional information is available to determine what this tool does.
Documented attack patterns abuse exactly the kind of access my_tool gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and FastMCP Multi-Tenancy, and nothing reaches the server without passing your rules. This is the rule we recommend for my_tool:
{
"version": "1",
"default": "deny",
"tools": {
"my_tool": {
"limits": [
{
"counter": "my_tool_rate",
"window": "minute",
"max": 60,
"scope": "grant"
}
]
}
}
}my_tool gets a rate cap, and everything else on the server is denied unless you say otherwise.

my_tool. It is categorised as a Other tool in the FastMCP Multi-Tenancy MCP Server, which means it performs auxiliary operations.
Register the FastMCP Multi-Tenancy MCP server in PolicyLayer and add a rule for my_tool: 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 FastMCP Multi-Tenancy. Nothing to install.
my_tool is a Other tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the my_tool 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 my_tool. 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.
my_tool is provided by the FastMCP Multi-Tenancy MCP server (timothywangdev/mcptoolkit). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from FastMCP Multi-Tenancy, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
