AI agents call list_servers to retrieve information from Komodo 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 existing servers without modifying, deleting, or executing any operations. It is a straightforward read operation that poses minimal risk if misused by an AI agent, as it only exposes infrastructure inventory information.
From the tool's definition Tool name 'list_servers' and description 'Lista todos los servidores disponibles en Komodo' (Lists all available servers in Komodo) indicate a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_servers gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Komodo MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list_servers:
{
"version": "1",
"default": "deny",
"tools": {
"list_servers": {}
}
}list_servers is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Lista todos los servidores disponibles en Komodo. It is categorised as a Read tool in the Komodo MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Komodo MCP Server MCP server in PolicyLayer and add a rule for list_servers: 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 Komodo MCP Server. Nothing to install.
list_servers 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_servers 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_servers. 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_servers is provided by the Komodo MCP Server MCP server (nonetss/komodo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Komodo 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.
