AI agents call list-products to retrieve information from Novita MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The verb 'list' performs a simple enumeration of data with no side effects. While the description is empty, the tool name and server context strongly suggest this retrieves product information without creating, modifying, or deleting data. The severity is low because listing products has minimal blast radius even if misused by an AI agent.
From the tool's definition Tool name is 'list-products' which indicates a retrieval/query operation. The pattern 'list-*' is characteristic of Read operations that enumerate or query data without modification.
Documented attack patterns abuse exactly the kind of access list-products gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Novita MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list-products:
{
"version": "1",
"default": "deny",
"tools": {
"list-products": {}
}
}list-products is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list-products. It is categorised as a Read tool in the Novita MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Novita MCP Server MCP server in PolicyLayer and add a rule for list-products: 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 Novita MCP Server. Nothing to install.
list-products 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-products 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-products. 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-products is provided by the Novita MCP Server MCP server (novitalabs/novita-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Novita MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
