Fetch a PromQL range query with auto-chosen step, returns TimeSeries.
AI agents call get_metric_trend to retrieve information from Mcp Deploy Intel without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves Prometheus metrics (monitoring/observability data). It has no side effects, does not modify state, and does not execute code or trigger deployments. The auto-chosen step is a query parameter optimization, not a control flow or execution mechanism.
From the tool's definition "Fetch a PromQL range query" — retrieves time series data from Prometheus metrics with no modification or execution of arbitrary commands. Returns TimeSeries, a read-only data structure.
Attacks that exploit this kind of access
Fetch a PromQL range query with auto-chosen step, returns TimeSeries. It is categorised as a Read tool in the Mcp Deploy Intel MCP Server, which means it retrieves data without modifying state.
Register the Mcp Deploy Intel MCP server in PolicyLayer and add a rule for get_metric_trend: 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 Deploy Intel. Nothing to install.
get_metric_trend 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_metric_trend 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_metric_trend. 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_metric_trend is provided by the Mcp Deploy Intel MCP server (vellankikoti/mcp-deploy-intel). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
