Get server mode and capabilities
AI agents call get_server_info to retrieve information from CERN ROOT MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only query of server information (mode, capabilities). It retrieves data with no side effects, state changes, or external operations. It is purely informational, making it a Read category tool with low severity since misuse cannot cause harm beyond information disclosure.
From the tool's definition Tool name and description indicate retrieval of metadata: 'Get server mode and capabilities' suggests querying status information about the server without modifying or executing operations.
Attacks that exploit this kind of access
Get server mode and capabilities. It is categorised as a Read tool in the CERN ROOT MCP Server MCP Server, which means it retrieves data without modifying state.
Register the CERN ROOT MCP Server MCP server in PolicyLayer and add a rule for get_server_info: 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 CERN ROOT MCP Server. Nothing to install.
get_server_info 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_server_info 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_server_info. 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_server_info is provided by the CERN ROOT MCP Server MCP server (mohamedelashri/root-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
