Report versions, detected features, and server limits.
AI agents call list_capabilities to retrieve information from Artillery MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves informational data about server capabilities, versions, and limits. It has no side effects, does not create, modify, or delete data, and does not execute external operations or consume resources. It is a pure read operation similar to 'get' or 'list' operations.
From the tool's definition Tool name 'list_capabilities' and description 'Report versions, detected features, and server limits' indicate a query operation that retrieves and reports metadata about the Artillery server without modifying any state or executing load tests.
Attacks that exploit this kind of access
Report versions, detected features, and server limits. It is categorised as a Read tool in the Artillery MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Artillery MCP Server MCP server in PolicyLayer and add a rule for list_capabilities: 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 Artillery MCP Server. Nothing to install.
list_capabilities 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_capabilities 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_capabilities. 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_capabilities is provided by the Artillery MCP Server MCP server (jch1887/artillery-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
