Read all VITAL metric samples from a RAMP test run (time-series data).
AI agents call get_test_vitals 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 historical metric data from a completed test run without side effects. It queries and returns existing data (time-series samples) without creating, modifying, deleting, or executing any operations. The 'Read' category applies to data retrieval operations with no side effects.
From the tool's definition Tool name includes 'get_' and description explicitly states 'Read all VITAL metric samples' with no modification, deletion, or execution capability. Returns time-series data only.
Attacks that exploit this kind of access
Read all VITAL metric samples from a RAMP test run (time-series data). 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_test_vitals: 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_test_vitals 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_test_vitals 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_test_vitals. 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_test_vitals 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.
