Security note

MCP servers receive tool arguments from a conversation and may perform external actions. Review what a server can do before you enable it, and give it only the access it needs.

The registry verified that this server's namespace belongs to usefulapi.io, which also runs its endpoint. That identifies the publisher; it does not make the server's tools safe.

SourceWeft's checks cover whether the listing is complete and the endpoint answered; they do not review the server's code or what its tools do.

Overview

AI-generated overview

Hosted WeatherLink server that lets an assistant list your weather stations and sensors and read current, historic and evapotranspiration data.

What you can do: List stations, nodes and sensors with their metadata
Check sensor activity to find sensors that stopped reporting
Read the latest observation per sensor for a station (temperature, humidity, wind, rain)
Fetch historic records for a station within a 24-hour window
Get evapotranspiration reports for WeatherLink Live stations
Check usage, request a feature, upgrade or cancel a plan
When to use it: Useful when you want an assistant to answer questions about your own WeatherLink weather stations, such as which are online, current conditions at a site, or how much rain fell yesterday, without building your own integration.
Requirements: Remote MCP endpoint connected by URL; sign-in is via OAuth, and on first connect you supply a WeatherLink API Key and API Secret generated on weatherlink.com. No keys go in the client config. A free plan allows 50 tool calls per month; paid plans raise the limit.

Before you install

You hand your WeatherLink API Key and API Secret to a third-party hosted service, which stores them per user. Historic data and recency depend on your WeatherLink subscription level. The server includes paid plans (Pro and Pro+) with Stripe checkout links, and upgrading or cancelling changes billing; the current period is not refunded on cancel.

Installation

In SourceWeft

Open WeatherLink MCP by usefulapi in the dashboard and add it to a workspace.
Enable the server for the chats that should use its tools.

Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.

Use with an agent

Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.

Read https://sourceweft.com/mcp/io.usefulapi%2Fweatherlink/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.

Read the install guide the agent follows

README

WeatherLink MCP by usefulapi

Use your WeatherLink account from Claude, Cursor, or any MCP client. Read your stations, sensors, current conditions, historic records and evapotranspiration data. Hosted, no local install: connect with your own credentials.

Live endpoint: https://weatherlink.usefulapi.io/mcp · Homepage: https://usefulapi.io

Connect

Claude (claude.ai, Desktop): open Customize → Connectors, click + Add → Add custom connector, and paste https://weatherlink.usefulapi.io/mcp.
Claude Code: claude mcp add --transport http weatherlink https://weatherlink.usefulapi.io/mcp, then run /mcp to log in.
VS Code: Add to VS Code.
Cursor and other clients: add the URL as a remote MCP server:

json

{  "mcpServers": {    "weatherlink": {      "url": "https://weatherlink.usefulapi.io/mcp"    }  }}

{  "mcpServers": {    "weatherlink": {      "url": "https://weatherlink.usefulapi.io/mcp"    }  }}

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your WeatherLink credentials.

Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/weatherlink/

On first connect you provide a WeatherLink API Key and WeatherLink API Secret, created on weatherlink.com → Account → Generate v2 Key. The server validates them and stores them per user. No keys go in config files.

read tools are read-only; write tools mutate data (clients should confirm them); meta tools report usage, manage your subscription or send a feature request.

Pricing

Each paid plan covers this server only. Ask your AI to run weatherlink_upgrade and choose Pro or Pro+, billed monthly or yearly (it returns a Stripe Checkout link). If you already have Pro, ask to change it to Pro+. The change requires your confirmation, keeps your billing interval and charges the price difference for the rest of the period immediately. Cancel any time with weatherlink_cancel_subscription: your paid plan continues to the end of the paid period, with no refund for the current period, and asking to resume the same plan with weatherlink_upgrade before then undoes the cancel. Or write to [email protected].

Parametersstation_ids

weatherlink_list_nodes

List nodes

List the nodes your API Key can access, with their metadata. WeatherLink v2: GET /v2/nodes (or /v2/nodes/{node-ids}).

Parametersnode_ids

List sensors

List the sensors your API Key can access, with their metadata. WeatherLink v2: GET /v2/sensors (or /v2/sensors/{sensor-ids}).

Parameterssensor_ids

weatherlink_get_sensor_activity

Get sensor activity

Get the last reporting time of sensors, to find sensors that stopped reporting. Leave sensor_ids empty for every sensor. WeatherLink v2: GET /v2/sensor-activity (or /v2/sensor-activity/{sensor-ids}).

Parameterssensor_ids

weatherlink_get_current_conditions

Get current conditions

Get the latest weather observation for one station, per sensor (for example temperature, humidity, wind and rain). How recent the record is depends on the access level: Pro+ gives the most recent record, Pro the most recent 5-minute record. WeatherLink v2: GET /v2/current/{station-id}.

Parametersstation_idrequired

Get historic weather records for one station between two Unix times. The window can be at most 24 hours (86400 seconds). Each record's timestamp is the END of its recording interval. Access depends on the subscription level (Basic has no historic data). WeatherLink v2: GET /v2/historic/{station-id}.

Parametersstation_idrequiredend_timestamprequiredstart_timestamprequired

weatherlink_get_et_report

Get evapotranspiration report

Get the evapotranspiration (ET) data for one WeatherLink Live station. Only WeatherLink Live stations report ET. WeatherLink v2: GET /v2/report/et/{station-id}.
