AI agents call invarium_list_test_runs to retrieve information from Invarium 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 invarium_list_test_runs 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.

List test runs for an agent or across all agents. Shows run status, pass rate, source, and date. Use this to see what test runs have been executed and their results. Args: agent_name: Optional — filter by agent name. If omitted, lists runs across all agents in your workspace. status: Optional — filter by status. Valid values: "completed", "failed", "running", "pending". limit: Maximum number of runs to return (default: 10). offset: Number of runs to skip for pagination (default: 0).. It is categorised as a Read tool in the Invarium MCP Server, which means it retrieves data without modifying state.
Register the Invarium MCP server in PolicyLayer and add a rule for invarium_list_test_runs: 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 Invarium. Nothing to install.
invarium_list_test_runs 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 invarium_list_test_runs 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 invarium_list_test_runs. 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.
invarium_list_test_runs is provided by the Invarium MCP server (invarium-ai/invarium). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
