Get Prometheus metrics (not available).
AI agents call get_prometheus_metrics to retrieve information from Session Buddy without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Prometheus metrics retrieval is a read-only operation that queries monitoring data. The '(not available)' notation indicates the tool may not be implemented or accessible, which reduces both the real-world risk and our confidence slightly, but the intended function remains a benign read operation.
From the tool's definition Tool name and description indicate retrieval of Prometheus metrics. Description states '(not available)', suggesting this tool is non-functional or a stub.

Register the Session Buddy MCP server in PolicyLayer and add a rule for get_prometheus_metrics: 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 Session Buddy. Nothing to install.
get_prometheus_metrics 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_prometheus_metrics 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_prometheus_metrics. 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.
