[DEMO] Get the current weather for a city.
AI agents call weather_current to retrieve information from Paid MCP Server Template without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves weather information for a specified city, which is a read-only operation. It does not modify, delete, or execute any actions. Even though the server itself implements payment gating via Mainlayer, the weather_current tool itself performs only a lookup/fetch operation. The [DEMO] prefix suggests this is a template example.
From the tool's definition Tool name and description indicate data retrieval: 'Get the current weather for a city.' This is a query operation with no side effects.

[DEMO] Get the current weather for a city. It is categorised as a Read tool in the Paid MCP Server Template MCP Server, which means it retrieves data without modifying state.
Register the Paid MCP Server Template MCP server in PolicyLayer and add a rule for weather_current: 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 Paid MCP Server Template. Nothing to install.
weather_current 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_current 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_current. 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.
weather_current is provided by the Paid MCP Server Template MCP server (mainlayer/paid-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
