Get statistics about ingestion and query performance from a Loki datasource
AI agents call get_loki_stats to retrieve information from Grafana MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves monitoring statistics (ingestion and query performance metrics) from Loki without side effects. It is a read-only query operation that does not create, modify, delete, or execute arbitrary code. The blast radius of misuse is minimal—an agent could retrieve internal performance data, which poses no operational risk.
From the tool's definition Tool name and description indicate 'Get statistics about ingestion and query performance' — purely retrieves/queries statistics from Loki datasource without modifying data or triggering external operations.
Attacks that exploit this kind of access
Get statistics about ingestion and query performance from a Loki datasource. It is categorised as a Read tool in the Grafana MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Grafana MCP Server MCP server in PolicyLayer and add a rule for get_loki_stats: 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 Server. Nothing to install.
get_loki_stats 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_loki_stats 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_loki_stats. 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_loki_stats is provided by the Grafana MCP Server MCP server (quanticsoul4772/grafana-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
