AI agents call get_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 and queries data about a test run without creating, modifying, deleting, or executing any operations. It is a straightforward data retrieval operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name is 'get_run' and description states 'Fetch the full metadata of a single test run' — the verb 'fetch' and passive retrieval of metadata indicate a read-only operation with no side effects.
Attacks that exploit this kind of access
Fetch the full metadata of a single test run. 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_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_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_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_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_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.
get_run is one line of Testrail's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
