Retrieves service dependencies for the given host
AI agents call get_service_dependencies to retrieve information from Nagios without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves configuration/status information about service dependencies in Nagios. It performs no data modification, deletion, code execution, or financial operations. The verb 'retrieves' and the read-only nature of dependency queries place it clearly in the Read category. Severity is low because misuse would only expose monitoring metadata with no blast radius for system integrity or operations.
From the tool's definition Tool name 'get_service_dependencies' and description 'Retrieves service dependencies' indicate a query operation that returns monitoring data without modification.
Documented attack patterns abuse exactly the kind of access get_service_dependencies gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Nagios, and nothing reaches the server without passing your rules. This is the rule we recommend for get_service_dependencies:
{
"version": "1",
"default": "deny",
"tools": {
"get_service_dependencies": {}
}
}get_service_dependencies is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Retrieves service dependencies for the given host. It is categorised as a Read tool in the Nagios MCP Server, which means it retrieves data without modifying state.
Register the Nagios MCP server in PolicyLayer and add a rule for get_service_dependencies: 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 Nagios. Nothing to install.
get_service_dependencies 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 get_service_dependencies 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 get_service_dependencies. 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.
get_service_dependencies is provided by the Nagios MCP server (prospire-technology-services/nagios-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Nagios, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
