US Drought Monitor severity for a county (5-digit FIPS) or state (2-letter). Weekly % of area in each category (None, D0 Abnormally Dry → D4 Exceptional), newest first, with the worst category per week. Keyless, public-domain (NDMC/USDA/NOAA). The official metric behind USDA disaster eligibility.
AI agents call agriculture.drought to retrieve information from Mcp without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This is a straightforward data retrieval tool that queries historical drought severity metrics. It has no side effects, does not modify data, and does not execute code or commands. While drought data may inform financial/agricultural decisions downstream, the tool itself only reads and returns public information.
From the tool's definition Tool retrieves and queries US Drought Monitor data ("Weekly % of area in each category", "newest first") for a specified county or state. No modification, deletion, or execution of external operations described. Keyless, public-domain data source.

US Drought Monitor severity for a county (5-digit FIPS) or state (2-letter). Weekly % of area in each category (None, D0 Abnormally Dry → D4 Exceptional), newest first, with the worst category per week. Keyless, public-domain (NDMC/USDA/NOAA). The official metric behind USDA disaster eligibility. It is categorised as a Read tool in the Mcp MCP Server, which means it retrieves data without modifying state.
Register the MCP server in PolicyLayer and add a rule for agriculture.drought: 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. Nothing to install.
agriculture.drought 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 agriculture.drought 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 agriculture.drought. 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.
agriculture.drought is provided by the MCP server (@2sio/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
