Get all metrics for a specific run with their latest values
AI agents call get_run_metrics to retrieve information from MLflow 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 metric data from a specific MLflow run. It performs a read-only query operation with no side effects, no code execution, no data modification, and no deletion. The action is informational and safe; misuse would only expose existing metrics data rather than cause harm through execution or destruction.
From the tool's definition Tool name 'get_run_metrics' and description 'Get all metrics for a specific run with their latest values' indicate a retrieval operation that queries and returns data without modifying or executing anything.
Documented attack patterns abuse exactly the kind of access get_run_metrics gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and MLflow MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_run_metrics:
{
"version": "1",
"default": "deny",
"tools": {
"get_run_metrics": {}
}
}get_run_metrics is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get all metrics for a specific run with their latest values. It is categorised as a Read tool in the MLflow MCP Server MCP Server, which means it retrieves data without modifying state.
Register the MLflow MCP Server MCP server in PolicyLayer and add a rule for get_run_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 MLflow MCP Server. Nothing to install.
get_run_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_run_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_run_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.
get_run_metrics is provided by the MLflow MCP Server MCP server (kkruglik/mlflow-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from MLflow MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
