get_results

Retrieve previously saved benchmark results from ~/.metrillm/results/. Optionally filter by model name. Returns an array of full benchmark result objects.

Part of the Metrillm server.

get_results is read-only, but an agent in a loop can still rack up calls and cost. PolicyLayer caps every call before it runs. Live in minutes.

AI agents call get_results to retrieve information from Metrillm without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though get_results only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access get_results gives an agent. Each links to the full case and the policy that stops it:

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so get_results only ever does what you allow.

What does the get_results tool do? +

Retrieve previously saved benchmark results from ~/.metrillm/results/. Optionally filter by model name. Returns an array of full benchmark result objects.. It is categorised as a Read tool in the Metrillm MCP Server, which means it retrieves data without modifying state.

How do I enforce a policy on get_results? +

Register the Metrillm MCP server in PolicyLayer and add a rule for get_results: 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 Metrillm. Nothing to install.

What risk level is get_results? +

get_results is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit get_results? +

Yes. Add a rate_limit block to the get_results 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.

How do I block get_results completely? +

Set action: deny in the PolicyLayer policy for get_results. 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.

What MCP server provides get_results? +

get_results is provided by the Metrillm MCP server (metrillm-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Metrillm tool call.
