Get detailed status of a specific PostgreSQL cluster.
AI agents call get_cluster_status to retrieve information from CloudNativePG 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 and queries status information about a PostgreSQL cluster without creating, modifying, or deleting any data. It is a read-only operation that returns observational data about cluster state, making it fall squarely into the Read category with low severity risk.
From the tool's definition Tool name 'get_cluster_status' and description 'Get detailed status of a specific PostgreSQL cluster' indicate a query/retrieval operation with no side effects.
Attacks that exploit this kind of access
Get detailed status of a specific PostgreSQL cluster. It is categorised as a Read tool in the CloudNativePG MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CloudNativePG MCP Server MCP server in PolicyLayer and add a rule for get_cluster_status: 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 CloudNativePG MCP Server. Nothing to install.
get_cluster_status 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 get_cluster_status 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 get_cluster_status. 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.
get_cluster_status is provided by the CloudNativePG MCP Server MCP server (wateim/cnpg-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
