AI agents call nebius_profiles to retrieve information from Nebius 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 configuration or profile information without side effects. It does not execute commands, modify data, delete resources, or perform financial operations. The action is read-only, making it a Read category risk with low severity since profile enumeration alone poses minimal risk to the system.
From the tool's definition Tool name 'nebius_profiles' and description 'Get the available Nebius CLI profiles' indicate a retrieval operation with no modification or execution of resources.
Documented attack patterns abuse exactly the kind of access nebius_profiles gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Nebius MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for nebius_profiles:
{
"version": "1",
"default": "deny",
"tools": {
"nebius_profiles": {}
}
}nebius_profiles is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the available Nebius CLI profiles. It is categorised as a Read tool in the Nebius MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Nebius MCP Server MCP server in PolicyLayer and add a rule for nebius_profiles: 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 Nebius MCP Server. Nothing to install.
nebius_profiles 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 nebius_profiles 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 nebius_profiles. 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.
nebius_profiles is provided by the Nebius MCP Server MCP server (nebius/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Nebius MCP Server, 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.
