## 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 2026-09-28.

- **Endpoint Security**: 74/100
  - 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.
  - HSTS check failed: the Strict-Transport-Security header is absent.
  - DNSSEC check failed: this domain isn't protected by DNSSEC.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 68/100
  - AI-judged instruction clarity (good).
  - Context-footprint check failed: tool/resource definitions use about 503 tokens (~167/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params.
  - 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 (100% 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 current MCP spec version (2026-07-28).

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

Vertical Weather is a hosted endpoint at https://api.verticalweather.com/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_atmospheric_profile` (~283 tokens)

Get an atmospheric profile

Wind, temperature, pressure, humidity and air density at chosen heights above a point.

        Each level has wind_u_ms (towards east), wind_v_ms (towards north), wind_speed_ms,
        wind_direction_deg (where the wind comes FROM, clockwise from north; 0 at zero speed
        means calm), temperature_k, pressure_pa, specific_humidity_kg_kg, relative_humidity_pct
        and density_kg_m3. valid_time is the model time actually used; provenance names the
        GFS run and grid point. Heights outside the model column are refused with the range
        that is available.

Input parameters:

- `altitude_reference` (string, required): agl: heights above ground level. msl: heights above mean sea level.
- `altitudes_m` (array, required): 1 to 32 different heights in metres.
- `ground_elevation_m_msl`: Optional site elevation in metres above sea level, used for agl heights instead of the model's terrain.
- `latitude` (number, required): Decimal degrees, north positive.
- `longitude` (number, required): Decimal degrees, east positive.
- `time` (string, required): ISO 8601 timestamp with a timezone, e.g. 2026-10-03T18:00:00Z. Up to 14 days ahead or about ten days back.

### `get_capabilities` (~28 tokens)

Get capabilities

Current coverage (time range, heights, fields) and usage limits. No API key needed.

### `get_usage` (~25 tokens)

Get usage

Today's data-fetch count and remaining daily allowance for the caller's account (UTC day).

## Common questions

### What is the Vertical Weather MCP server?

Vertical Weather is an MCP server listed in the public MCP registry as com.verticalweather/vertical-weather. Wind, temperature, pressure, humidity and air density at chosen heights, from NOAA GFS. This page covers its hosted endpoint (https://api.verticalweather.com/mcp).

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

Vertical Weather scores 71 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 Vertical Weather MCP server expose?

Vertical Weather exposes 3 tools: get_atmospheric_profile, get_capabilities, get_usage. Their descriptions and schemas cost roughly 336 tokens of context every time the server is loaded.

### Does the Vertical Weather MCP server require authentication?

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

### Is the Vertical Weather MCP server still maintained?

Vertical Weather is still listed as active in the MCP registry. We last reached this channel on 28 September 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.
