Get current air quality index (AQI) and pollutant levels for a city.
AI agents call get_air_quality to retrieve information from Weather MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves real-time air quality data from an external API (Open-Meteo). It performs no write operations, does not execute code, does not delete data, and involves no financial transactions. The verb 'Get' and the read-only nature of AQI/pollutant level queries classify this as a Read operation with minimal blast radius if misused by an AI agent.
From the tool's definition Tool name 'get_air_quality' and description 'Get current air quality index (AQI) and pollutant levels for a city' indicate retrieval of data with no modification or side effects.

Register the Weather MCP Server MCP server in PolicyLayer and add a rule for get_air_quality: 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 Weather MCP Server. Nothing to install.
get_air_quality 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_air_quality 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_air_quality. 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_air_quality is provided by the Weather MCP Server MCP server (shreyaschhabra/weather-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
