query_loki_logs
Run LogQL queries for logs and metrics
Part of the Grafana MCP server. Enforce policies on this tool with Intercept, the open-source MCP proxy.
WHEN AI AGENTS USE THIS TOOL
AI agents call query_loki_logs to retrieve information from Grafana without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions — but you may still want rate limits to control API costs.
WHY ENFORCE A POLICY ON QUERY_LOKI_LOGS
Even though query_loki_logs only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.
RECOMMENDED POLICY
Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

FREQUENTLY ASKED QUESTIONS
What does the query_loki_logs tool do?
Run LogQL queries for logs and metrics. It is categorised as a Read tool in the Grafana MCP Server, which means it retrieves data without modifying state.
How do I enforce a policy on query_loki_logs?
Add a rule in your Intercept YAML policy under the tools section for query_loki_logs. You can allow, deny, rate-limit, or validate arguments. Then run Intercept as a proxy in front of the Grafana MCP server.
What risk level is query_loki_logs?
query_loki_logs is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Can I rate-limit query_loki_logs?
Yes. Add a rate_limit block to the query_loki_logs rule in your Intercept 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.
How do I block query_loki_logs completely?
Set action: deny in the Intercept policy for query_loki_logs. 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.
What MCP server provides query_loki_logs?
query_loki_logs is provided by the Grafana MCP server (grafana/mcp-grafana). Intercept sits as a proxy in front of this server to enforce policies before tool calls reach the server.
