Agent View of the PolicyLayer registry record for `weather`. HTML page: https://policylayer.com/tools/firebase-genkit/weather

## Facts

- Tool: `weather`
- Server: Genkit MCP (`genkit-ai/genkit`) — https://policylayer.com/tools/firebase-genkit.md
- Homepage: https://github.com/genkit-ai/genkit
- Risk category: Read (Low risk)
- Registry record: grade F, identity unverified
- Server rate-limited: no
- Parameters: 0
- Recommended policy verdict: Allowed

## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/call",
  "params": {
    "name": "weather",
    "arguments": {}
  }
}
```

## Why weather is rated Low

The tool retrieves weather information for a specified city. This is a read-only query that does not create, modify, delete, or execute any operations. The blast radius of misuse is minimal, as returning incorrect or fabricated weather data poses no direct risk to systems, finances, or data integrity. Severity is low because the worst outcome is providing inaccurate weather information.

From the tool's own definition: "Tool name is 'weather' and description states 'Get the weather for a city' — this is a data retrieval operation with no side effects."

## Use case

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

## Recommended policy (PolicyLayer)

Verdict: **Allowed**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Genkit MCP:

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

## For agents

This record is a snapshot. Live verdicts and the full registry:

- Check every server in your MCP config at once: `npx -y policylayer stack`
- Vet a server before you add it: install the mcp-precheck skill — `npx skills add https://policylayer.com` (skill text: https://policylayer.com/skill.md)
- Query the registry over MCP: endpoint `https://api.policylayer.com/mcp` — tools `check_mcp_server`, `check_mcp_stack`, `check_tool`, `search_registry`, `get_change_events`
