List agent-readable XGR and XDaLa standards available in the MCP knowledge base.
AI agents call list_xgr_standards to retrieve information from XGR MCP Gateway without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and lists standards from a knowledge base. The verb 'list' and the read-only nature of querying available standards without modification, creation, or deletion means this is a Read operation. The severity is low because retrieving public standards information poses minimal risk even if misused by an AI agent.
From the tool's definition Tool name 'list_xgr_standards' and description 'List agent-readable XGR and XDaLa standards available in the MCP knowledge base' indicate a retrieval operation with no side effects.
Attacks that exploit this kind of access
List agent-readable XGR and XDaLa standards available in the MCP knowledge base. It is categorised as a Read tool in the XGR MCP Gateway MCP Server, which means it retrieves data without modifying state.
Register the XGR MCP Gateway MCP server in PolicyLayer and add a rule for list_xgr_standards: 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 XGR MCP Gateway. Nothing to install.
list_xgr_standards 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_xgr_standards 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_xgr_standards. 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_xgr_standards is provided by the XGR MCP Gateway MCP server (xgr-network/xgr-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
