Get air quality information for a specified city including PM2.5, PM10, ozone, nitrogen dioxide, carbon monoxide, and other pollutants. Provides health advisories based on current air quality levels.
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.
| Parameter | Type | Required | Description |
|---|---|---|---|
city | string | — | The name of the city to fetch air quality information for, PLEASE NOTE English name only, if the parameter city isn't English please translate to English before |
variables | array | — | Air quality variables to retrieve. If not specified, defaults to pm10, pm2_5, ozone, nitrogen_dioxide, and carbon_monoxide. |
Parameters from the server's own tool schema.
This tool retrieves and queries air quality data (PM2.5, PM10, ozone, nitrogen dioxide, carbon monoxide) for a specified city. It returns information and health advisories but does not create, modify, delete, or execute any external operations. This is a straightforward data retrieval operation with no side effects, fitting the Read category.
From the tool's definition Tool description explicitly states 'Get air quality information' and 'Provides health advisories' — purely informational operations with no data modification, deletion, or external side effects.
Documented attack patterns abuse exactly the kind of access get_air_quality gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Weather MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for get_air_quality:
{
"version": "1",
"default": "deny",
"tools": {
"get_air_quality": {}
}
}get_air_quality is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get air quality information for a specified city including PM2.5, PM10, ozone, nitrogen dioxide, carbon monoxide, and other pollutants. Provides health advisories based on current air quality levels. It is categorised as a Read tool in the Weather MCP Server MCP Server, which means it retrieves data without modifying state.
get_air_quality accepts 2 parameters: city, variables. The full parameter table on this page comes from the server's own tool schema.
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 (isdaniel/mcp_weather_server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Weather MCP Server, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
