AI agents use update_server to create or update resources in Komodo — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Komodo environment.
The tool modifies existing server resources in the Komodo DevOps platform, making it a Write operation. While the description is empty (lowering confidence slightly), the name and context indicate reversible modifications to server configuration rather than irreversible deletion or financial impact.
From the tool's definition Tool name 'update_server' indicates modification of server configuration. Sibling tools include destructive operations (delete_alerter, delete_build) and create operations (create_server, create_deployment), placing this in a DevOps infrastructure management…
Documented attack patterns abuse exactly the kind of access update_server gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Komodo, and nothing reaches the server without passing your rules. This is the rule we recommend for update_server:
{
"version": "1",
"default": "deny",
"tools": {
"update_server": {
"limits": [
{
"counter": "update_server_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}update_server stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

update_server. It is categorised as a Write tool in the Komodo MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
Register the Komodo MCP server in PolicyLayer and add a rule for update_server: 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. Nothing to install.
update_server is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the update_server 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 update_server. 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.
update_server is provided by the Komodo MCP server (myrikld/komodo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Komodo, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
