AI agents call get_tests_in_run to retrieve information from Testrail without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves existing test information from a TestRail run. The verb 'get' combined with the description showing it returns status data confirms a read-only operation that does not create, modify, delete, or execute anything. It has minimal blast radius—an AI agent cannot cause harm by retrieving test run data.
From the tool's definition Tool name 'get_tests_in_run' and description 'Tests in a run with their current status (current = latest result)' indicate retrieval of test metadata and status information with no modification or side effects.

Register the Testrail MCP server in PolicyLayer and add a rule for get_tests_in_run: 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 Testrail. Nothing to install.
get_tests_in_run 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_tests_in_run 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_tests_in_run. 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_tests_in_run is provided by the Testrail MCP server (sergey-bl/testrail-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
