Get the list of nodes for a specific CCX datastore, including their roles, status, and IP addresses
AI agents call ccx_get_nodes to retrieve information from Severalnines CCX 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 information about database cluster nodes (their roles, status, and IP addresses) without making any changes to the system or triggering external operations. It is a read-only query operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name is 'ccx_get_nodes' and description states it 'Get the list of nodes for a specific CCX datastore, including their roles, status, and IP addresses' — purely a retrieval operation with no modification or execution.
Attacks that exploit this kind of access
Get the list of nodes for a specific CCX datastore, including their roles, status, and IP addresses. It is categorised as a Read tool in the Severalnines CCX MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Severalnines CCX MCP Server MCP server in PolicyLayer and add a rule for ccx_get_nodes: 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 Severalnines CCX MCP Server. Nothing to install.
ccx_get_nodes 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 ccx_get_nodes 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 ccx_get_nodes. 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.
ccx_get_nodes is provided by the Severalnines CCX MCP Server MCP server (severalnines/ccx-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
