list_loki_apps
AI agents call list_loki_apps to retrieve information from MCP Prometheus without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool name and its membership in a pattern of list/query operations on a monitoring system strongly suggest it retrieves or enumerates Loki applications without side effects. Although the description is empty (lowering confidence slightly), the naming convention and context within a Prometheus/Loki monitoring server make a Read classification appropriate with medium-high confidence.
From the tool's definition Tool name 'list_loki_apps' follows the 'list_*' pattern consistent with sibling tools 'list_checks', 'list_environments', 'list_loki_environments', 'list_loki_hosts', 'list_process_groups', and 'list_servers', all of which are read-only queries.

list_loki_apps. It is categorised as a Read tool in the MCP Prometheus MCP Server, which means it retrieves data without modifying state.
Register the MCP Prometheus MCP server in PolicyLayer and add a rule for list_loki_apps: 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 MCP Prometheus. Nothing to install.
list_loki_apps 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_loki_apps 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_loki_apps. 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_loki_apps is provided by the MCP Prometheus MCP server (yeonkyu-git/mcp-prometheus-loki). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
