Latest real-time surface weather observations from Environment Canada stations near a point (swob-realtime). Returns station name, observation time, air temp, dewpoint, humidity, wind, pressure, snow depth. Example: latitude 43.65, longitude -79.38 for Toronto. Keyless, official ECCC data.
AI agents call current_observations to retrieve information from Mcp Weather Gc Ca without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
| Parameter | Type | Required | Description |
|---|---|---|---|
limit | number | — | Max observations to return (default 5, max 20). |
latitude | number | Yes | Latitude in decimal degrees, e.g. 43.65 (Toronto). |
longitude | number | Yes | Longitude in decimal degrees, e.g. -79.38 (Toronto). |
Parameters from the server's own tool schema.
This tool queries publicly available weather data from Environment and Climate Change Canada with no side effects. It is a read-only operation that retrieves but does not modify, execute, or delete any data. The low severity reflects that misuse would only expose already-public weather information with no blast radius beyond information disclosure.
From the tool's definition Tool retrieves 'Latest real-time surface weather observations' and 'Returns station name, observation time, air temp, dewpoint, humidity, wind, pressure, snow depth.' No modification, deletion, or execution capabilities described.
Attacks that exploit this kind of access
Latest real-time surface weather observations from Environment Canada stations near a point (swob-realtime). Returns station name, observation time, air temp, dewpoint, humidity, wind, pressure, snow depth. Example: latitude 43.65, longitude -79.38 for Toronto. Keyless, official ECCC data. It is categorised as a Read tool in the Mcp Weather Gc Ca MCP Server, which means it retrieves data without modifying state.
current_observations accepts 3 parameters: limit, latitude, longitude. Required: latitude, longitude. The full parameter table on this page comes from the server's own tool schema.
Register the Mcp Weather Gc Ca MCP server in PolicyLayer and add a rule for current_observations: 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 Mcp Weather Gc Ca. Nothing to install.
current_observations 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 current_observations 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 current_observations. 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.
current_observations is provided by the Mcp Weather Gc Ca MCP server (https://gateway.pipeworx.io/weather-gc-ca/mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
