Retrieves current weather information and forecast for a specified location
AI agents call weather to retrieve information from Creating Your First without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves data (current weather and forecast) without modifying, deleting, or executing any external operations. It is a straightforward read operation with minimal security risk if misused, as the worst outcome would be retrieving weather data for unintended locations.
From the tool's definition Tool description states it 'Retrieves current weather information and forecast for a specified location' — a query operation with no side effects.

Retrieves current weather information and forecast for a specified location. It is categorised as a Read tool in the Creating Your First MCP Server, which means it retrieves data without modifying state.
Register the Creating Your First MCP server in PolicyLayer and add a rule for weather: 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 Creating Your First. Nothing to install.
weather 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 weather 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 weather. 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.
