Simple connectivity check
AI agents call hello to retrieve information from CubeCobra MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
A connectivity check is a read-only diagnostic operation with no ability to access, modify, or affect cube data or any other resources. It poses minimal risk even if called by an AI agent, as it only validates server availability.
From the tool's definition Tool name 'hello' and description 'Simple connectivity check' indicate a non-operational probe that retrieves no sensitive data and performs no modifications, deletions, or side effects.
Attacks that exploit this kind of access
Simple connectivity check. It is categorised as a Read tool in the CubeCobra MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CubeCobra MCP Server MCP server in PolicyLayer and add a rule for hello: 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 CubeCobra MCP Server. Nothing to install.
hello 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 hello 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 hello. 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.
hello is provided by the CubeCobra MCP Server MCP server (plrdev/cubecobra-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
