Test connectivity to a Kusto cluster using a saved connection.
AI agents call kusto_connection_test to retrieve information from Kusto MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Testing connectivity is a read-only operation that checks whether a connection can be established. It retrieves or probes status without creating, modifying, or deleting any data. Misuse potential is low as it only verifies reachability.

Attacks that exploit this kind of access
Test connectivity to a Kusto cluster using a saved connection. It is categorised as a Read tool in the Kusto MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Kusto MCP Server MCP server in PolicyLayer and add a rule for kusto_connection_test: 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 Kusto MCP Server. Nothing to install.
kusto_connection_test 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 kusto_connection_test 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 kusto_connection_test. 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.
kusto_connection_test is provided by the Kusto MCP Server MCP server (yeshsurya/kusto-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
