WHAT IT DOES

What weather does on Marketplace

AI agents call weather to retrieve information from Marketplace without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

Parameter	Type	Required	Description
`lat`	number	Yes
`lon`	number	Yes

Parameters from the server's own tool schema.

RISK

Why weather is rated Low

Even though weather only reads data, uncontrolled read access leaks sensitive information and racks up API costs: an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.

Attacks that exploit this kind of access

RECOMMENDED RULE

The rule that runs weather safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Marketplace, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For weather, this is the rule to start with:

weather Allowed

weather is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.

View as policy code

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "weather": {}
  }
}

ALLOW ONLY THIS TOOL → Instant setup, no code required.

The button opens the PolicyLayer dashboard: create your workspace, connect Marketplace, apply this rule, and every weather call is checked against it from then on.
