Get detailed information about a specific CephFS filesystem
AI agents call get_fs_details 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 tool retrieves filesystem metadata and status information from a Ceph cluster without performing any write, delete, or execution operations. It is a straightforward query operation consistent with other sibling tools (get_cluster_capacity, get_health_details, etc.). The read-only nature makes it low severity even in a misconfigured context.
From the tool's definition Tool name includes 'get_' prefix and description states 'Get detailed information about a specific CephFS filesystem' — a retrieval operation with no modification or deletion.
Documented attack patterns abuse exactly the kind of access get_fs_details 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_fs_details:
{
"version": "1",
"default": "deny",
"tools": {
"get_fs_details": {}
}
}get_fs_details is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get detailed information about a specific CephFS filesystem. 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_fs_details: 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_fs_details 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_fs_details 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_fs_details. 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_fs_details 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.
