AI agents call get_results_for_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 retrieves historical test execution results and metadata (comments, defects, tester information, timestamps) from a test run without modifying, deleting, or executing any operations. It is a pure read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool description states 'All result entries for a run — includes comments, defects, who tested when.' The verb 'get' combined with 'results for a run' indicates retrieval/querying of existing test data with no side effects.

All result entries for a run — includes comments, defects, who tested when. It is categorised as a Read tool in the Testrail MCP Server, which means it retrieves data without modifying state.
Register the Testrail MCP server in PolicyLayer and add a rule for get_results_for_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_results_for_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_results_for_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_results_for_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_results_for_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.
