Vertical Weather MCP server
Which MCP servers are Vertical Weather's own, from the official registry and from asking its own domain, whether they answer, and what they offer. A program checked each of these, nobody copied them from a product page.

- Registry namecom.verticalweather/vertical-weatherverified in the MCP registry
The registry name sits under verticalweather.com. The registry only lets a publisher use that namespace after proving control of the domain through DNS or HTTP.

On 2026-11-01 the server answered initialize and tools/list without a sign-in. First answer in 151 ms.
- Its tools do every use case we checked: fetch wind speed and direction at set heights above ground; check air density aloft before drone or rocket flights; pull forecast profiles up to 10 km for balloon launches.
- Checked on 2 of the 7 days it takes to judge reliability.
Once connected
- For "fetch wind speed and direction at set heights above ground", the likely first call is get_atmospheric_profile.
- For "check air density aloft before drone or rocket flights", the likely first call is get_atmospheric_profile.
- For "pull forecast profiles up to 10 km for balloon launches", the likely first call is get_atmospheric_profile.
Said by rules from the measurements above. The likely first call is a model's pick from the tool list; read its description before relying on it.

Each of the product's use cases, put to Jev against this server's tool list: can an agent do it with these tools?
Worth a look
None of the five warning signs in these definitions.
A program checks the server once a day: initialize and tools/list, no model. Tokens are the definitions' length at about four characters a token. The grade averages six checks of every tool's name, description, schema and annotations; it says how well the tools are described, not whether they work. The score weighs what was measured and nothing else: answering (25%), doing the product's job (25%), definitions (20%), context (10%), use (10%) and how readily a client connects (10%). A part that was not measured is left out, and a hidden instruction caps the score at 40. The state of vendors' MCP servers: method and numbers →
get_atmospheric_profileWind, 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…
get_capabilitiesCurrent coverage (time range, heights, fields) and usage limits. No API key needed.
get_usageToday's data-fetch count and remaining daily allowance for the caller's account (UTC day).
How to connect
Add the server to your MCP client config. Claude Desktop, Cursor and most other clients read this shape:
{
"mcpServers": {
"vertical-weather": {
"type": "http",
"url": "https://api.verticalweather.com/mcp"
}
}
}Add it
Claude Code, in a terminal
claude mcp add --transport http verticalweather https://api.verticalweather.com/mcpclaude.ai, ChatGPT and other clients: add https://api.verticalweather.com/mcp as a custom connector in the settings.

Each line is something a program found when it went looking: the registry entry, the server's own answer, a spec that parses. A missing line means we did not find it, not that it does not exist.
