AI agents call get_pool_summary to retrieve information from Ceph 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 query function that retrieves summary information about Ceph storage pools. It has no side effects, does not execute commands, and does not modify cluster state. The naming convention ('get_' prefix) and context among sibling tools (all queries: get_cluster_capacity, get_daemon_details, etc.) confirm it is a passive information retrieval tool.
From the tool's definition Tool name 'get_pool_summary' and description 'Get cluster pool summary' indicate a retrieval operation that queries pool metadata without modifying or executing operations.
Documented attack patterns abuse exactly the kind of access get_pool_summary gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Ceph MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_pool_summary:
{
"version": "1",
"default": "deny",
"tools": {
"get_pool_summary": {}
}
}get_pool_summary is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get cluster pool summary. It is categorised as a Read tool in the Ceph MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Ceph MCP Server MCP server in PolicyLayer and add a rule for get_pool_summary: 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 Ceph MCP Server. Nothing to install.
get_pool_summary 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_pool_summary 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_pool_summary. 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_pool_summary is provided by the Ceph MCP Server MCP server (rajmohanram/ceph-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Ceph MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
