AI agents call get_lightweight_mode_info to retrieve information from Xugu without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves configuration or state information about a Chat2SQL mode setting. It performs a query operation with no side effects—it neither modifies data, executes code, deletes resources, nor commits financial transactions. The low severity reflects minimal risk even if misused by an agent, as it only surfaces existing metadata about the system's operational mode.
From the tool's definition Tool name 'get_lightweight_mode_info' and description 'Get information about lightweight Chat2SQL mode' indicate a retrieval/query operation.

Get information about lightweight Chat2SQL mode. It is categorised as a Read tool in the Xugu MCP Server, which means it retrieves data without modifying state.
Register the Xugu MCP server in PolicyLayer and add a rule for get_lightweight_mode_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 Xugu. Nothing to install.
get_lightweight_mode_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_lightweight_mode_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_lightweight_mode_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_lightweight_mode_info is provided by the Xugu MCP server (leokupo/xugu-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
