AI agents call list_queries to retrieve information from Grafana Mcp Analyzer without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool lists or enumerates existing Grafana query configurations to inform subsequent analysis. This is a read-only operation that retrieves metadata about available queries without modifying, executing, or deleting any data. The low severity reflects minimal blast radius—unauthorized listing of query configurations poses an information disclosure risk but no direct operational impact.
From the tool's definition Tool name is 'list_queries' and description indicates it 'views available Grafana query configurations' (查看可用的Grafana查询配置). This is a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access list_queries gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Grafana Mcp Analyzer, and nothing reaches the server without passing your rules. This is the rule we recommend for list_queries:
{
"version": "1",
"default": "deny",
"tools": {
"list_queries": {}
}
}list_queries is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Register the Grafana Mcp Analyzer MCP server in PolicyLayer and add a rule for list_queries: 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 Grafana Mcp Analyzer. Nothing to install.
list_queries 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_queries 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_queries. 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_queries is provided by the Grafana Mcp Analyzer MCP server (sailingcoder/grafana-mcp-analyzer). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
