Get river discharge and flood forecasts from GloFAS (Global Flood Awareness System).
AI agents call flood_forecast to retrieve information from Open Meteo without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves forecasted flood and river discharge data from an external API (GloFAS). It performs a read-only query with no side effects on data creation, modification, deletion, or external command execution. Misuse by an AI agent would result in retrieving potentially stale or irrelevant flood forecast data, a low-impact outcome with no destructive or financial consequences.
From the tool's definition Tool name 'flood_forecast' and description 'Get river discharge and flood forecasts' indicate data retrieval with no modification, deletion, or execution of external operations. The verb 'Get' explicitly denotes a query operation.
Attacks that exploit this kind of access
Get river discharge and flood forecasts from GloFAS (Global Flood Awareness System). It is categorised as a Read tool in the Open Meteo MCP Server, which means it retrieves data without modifying state.
Register the Open Meteo MCP server in PolicyLayer and add a rule for flood_forecast: 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 Open Meteo. Nothing to install.
flood_forecast 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 flood_forecast 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 flood_forecast. 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.
flood_forecast is provided by the Open Meteo MCP server (windsornguyen/open-meteo-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
