Fetch a sub-test-plan (STP-*) under a parent plan (TP-*). Returns metadata and linked test runs.
AI agents call getSubTestPlan to retrieve information from BrowserStack without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves and queries test plan metadata and associated test runs. It performs a lookup/fetch operation with no side effects, no data modification, no code execution, and no financial impact. This is a straightforward data retrieval action typical of Read category tools.
From the tool's definition Tool description states 'Fetch a sub-test-plan' and 'Returns metadata and linked test runs' — these are read-only retrieval operations with no modification, deletion, or execution of external systems.
Attacks that exploit this kind of access
Fetch a sub-test-plan (STP-*) under a parent plan (TP-*). Returns metadata and linked test runs. It is categorised as a Read tool in the BrowserStack MCP Server, which means it retrieves data without modifying state.
Register the BrowserStack MCP server in PolicyLayer and add a rule for getSubTestPlan: 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 BrowserStack. Nothing to install.
getSubTestPlan 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 getSubTestPlan 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 getSubTestPlan. 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.
getSubTestPlan is provided by the BrowserStack MCP server (browserstack/mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
