AI agents use create_alerter 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.
This tool creates a new monitoring/alerting entity in the DevOps platform. While it modifies state, it does not delete data, execute arbitrary commands, or involve financial transactions. It is reversible (delete_alerter exists), making it Write rather than Destructive. The blast radius is limited to alerts configuration.
From the tool's definition Tool name is 'create_alerter' and description states 'Create a new alerter.' This is a data creation operation that modifies the alerter configuration within the Komodo DevOps platform. It is reversible via delete_alerter (present as a sibling tool).
Documented attack patterns abuse exactly the kind of access create_alerter 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 create_alerter:
{
"version": "1",
"default": "deny",
"tools": {
"create_alerter": {
"limits": [
{
"counter": "create_alerter_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_alerter 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.

Create a new alerter. 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 create_alerter: 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.
create_alerter 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 create_alerter 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 create_alerter. 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.
create_alerter 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.
Free to start. No card required.
