AI agents call list_shifts to retrieve information from Rootly without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The 'list_shifts' operation is a read-only query that retrieves shift information from the oncall management system. It has no side effects and does not create, modify, delete, or execute operations. Confidence is slightly reduced due to missing description, but the function name and context are sufficient to classify with high confidence.
From the tool's definition Tool name 'list_shifts' indicates a retrieval operation. No description provided, but naming convention and sibling tools (get_incident, get_alert_by_short_id, get_oncall_schedule_summary) suggest this queries oncall/shift data without modification.
Documented attack patterns abuse exactly the kind of access list_shifts gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Rootly, and nothing reaches the server without passing your rules. This is the rule we recommend for list_shifts:
{
"version": "1",
"default": "deny",
"tools": {
"list_shifts": {}
}
}list_shifts is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

list_shifts. It is categorised as a Read tool in the Rootly MCP Server, which means it retrieves data without modifying state.
Register the Rootly MCP server in PolicyLayer and add a rule for list_shifts: 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 Rootly. Nothing to install.
list_shifts 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_shifts 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_shifts. 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_shifts is provided by the Rootly MCP server (https://mcp.rootly.com/sse). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Rootly, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
