AI agents call list_updates 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 retrieves information about recent updates without modifying, executing, or deleting any data. It is a read-only operation that matches the 'Read' category definition of retrieving or querying data with no side effects.
From the tool's definition Tool name 'list_updates' and description 'Lista las actualizaciones recientes' (Lists recent updates) indicate a retrieval/query operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_updates 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_updates:
{
"version": "1",
"default": "deny",
"tools": {
"list_updates": {}
}
}list_updates is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Lista las actualizaciones recientes. 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_updates: 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_updates 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_updates 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_updates. 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_updates 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.
