## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-10-23.

- **Endpoint Security**: 83/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - No authorisation is required to call this server. Every tool declares its destructiveHint and none is destructive, so open access doesn't expose one.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 71/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 324 tokens (~108/item across 3 items; 3 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 7/100
  - Stability observed for 2 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (67% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## Install

### How do I install the Weather MCP server?

Weather is a hosted endpoint at https://agent-evidence.thx93.dev/weather/mcp, so there is nothing to install locally. Ready-made configuration for Claude, Cursor, VS Code, Codex and 5 more is on this page, copied from each client's own documentation.

## MCP tools (3)

### `get-alerts` (~132 tokens)

Get Weather Alerts

Get active weather alerts for a US state. Give the two-letter state code (for example CA or NY) and get every active National Weather Service alert for it: the event type, the area it covers, its severity, what is happening, and the official instruction. US locations only. No API key and no account: discovery is free, a call costs $0.01 in USDC on Base via x402, and nothing is charged when the request returns no data. Free tools: health and tools/list.

Input parameters:

- `state` (string, required): Two-letter US state code (e.g. CA, NY)

Output parameters:

- `alerts` (array)

### `get-forecast` (~124 tokens)

Get Weather Forecast

Get the weather forecast for a point on the map. Give latitude and longitude and get the next five forecast periods for it: the period name, its temperature, wind speed and direction, and the plain-language forecast. US locations only. No API key and no account: discovery is free, a call costs $0.01 in USDC on Base via x402, and nothing is charged when the request returns no data. Free tools: health and tools/list.

Input parameters:

- `latitude` (number, required): Latitude of the location
- `longitude` (number, required): Longitude of the location

Output parameters:

- `latitude` (number)
- `longitude` (number)
- `periods` (array)

### `health` (~17 tokens)

Health

Check that the service is up. Costs nothing.

## Common questions

### What is the Weather MCP server?

Weather is an MCP server listed in the public MCP registry as io.github.Thx93/weather. US NWS weather alerts and 5-day forecasts for AI agents. $0.01 per call. This page covers its hosted endpoint (https://agent-evidence.thx93.dev/weather/mcp).

### Is the Weather MCP server safe to use?

Weather scores 75 out of 100 on VerifyMCP. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Weather MCP server expose?

Weather exposes 3 tools: get-alerts, get-forecast, health. Their descriptions and schemas cost roughly 273 tokens of context every time the server is loaded.

### Does the Weather MCP server require authentication?

No. We connected to Weather without credentials and it answered, so anything it exposes is reachable by anyone who knows the address.

### Is the Weather MCP server still maintained?

Weather is still listed as active in the MCP registry. We last reached this channel on 23 October 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
