AI agents call list_test_cases to retrieve information from 3gpp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves and lists test case sections from 3GPP specification documents. It has no side effects, does not modify any data, and is purely a read/query operation. Misuse potential is minimal as it only returns structured document information.
From the tool's definition 'List structured 3GPP conformance test case sections for a specification' — purely retrieves/lists data with optional filtering
Attacks that exploit this kind of access
List structured 3GPP conformance test case sections for a specification, with optional section-prefix filtering. It is categorised as a Read tool in the 3gpp MCP Server, which means it retrieves data without modifying state.
Register the 3gpp MCP server in PolicyLayer and add a rule for list_test_cases: 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 3gpp. Nothing to install.
list_test_cases 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 list_test_cases 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 list_test_cases. 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.
list_test_cases is provided by the 3gpp MCP server (lee-sihyeon/mcp-server-3gpp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
