List all parameter groups (database configuration templates). Optionally filter by database vendor, version, or name. Returns a paginated list with name, vendor, version, description, and associated datastores.
AI agents call ccx_list_parameter_groups 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 is a read-only operation that queries and retrieves information about parameter groups. It has no side effects, makes no modifications to the database system, and merely returns existing configuration metadata. The filtering options (by vendor, version, name) are all read parameters that do not affect data integrity. Blast radius from misuse is minimal—an attacker could only learn about existing configurations.
From the tool's definition Tool name contains 'list' and description states it 'List all parameter groups' and 'Returns a paginated list'. The operation retrieves configuration templates without modifying, deleting, or executing changes.
Attacks that exploit this kind of access
List all parameter groups (database configuration templates). Optionally filter by database vendor, version, or name. Returns a paginated list with name, vendor, version, description, and associated datastores. 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_list_parameter_groups: 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_list_parameter_groups 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_list_parameter_groups 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_list_parameter_groups. 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_list_parameter_groups 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.
