AI agents call list_selections to retrieve information from Mcp Csu without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves metadata about available data selections through pagination. It has no side effects—it only queries and returns information about what data tables exist in the system. The pagination mechanism is a standard read operation pattern. There is no capability to modify, delete, or execute arbitrary operations.
From the tool's definition Tool name 'list_selections' and description 'List all predefined data tables (selections) with pagination' indicate a read-only operation that retrieves and enumerates existing data structures without modifying, executing code, or deleting anything.
Attacks that exploit this kind of access
List all predefined data tables (selections) with pagination. It is categorised as a Read tool in the Mcp Csu MCP Server, which means it retrieves data without modifying state.
Register the Mcp Csu MCP server in PolicyLayer and add a rule for list_selections: 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 Mcp Csu. Nothing to install.
list_selections 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 list_selections 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 list_selections. 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.
list_selections is provided by the Mcp Csu MCP server (reloadcz/mcp-csu). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
list_selections is one line of Mcp Csu's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
